Can Stem Cell ‘Patch’ Help Heart Failure? – Everyday Health (blog)
By daniellenierenberg
Scientists report another step in the use of stem cells to help treat people with debilitating heart failure.
In an early study of 27 patients, Japanese researchers used patients' own muscle stem cells to create a "patch" that was placed on the heart.
Over the next year, the patients generally showed small improvements in their symptoms -- including the ability to walk without becoming breathless and fatigued.
However, experts cautioned that while the results are encouraging, there's a lot of work left ahead before stem cells can be used to treat heart failure.
"They've shown that this approach is feasible," said Dr. Eiran Gorodeski, a heart failure specialist at the Cleveland Clinic in Ohio.
But it's not clear whether the stem-cell tactic was actually effective, said Gorodeski, who was not involved in the study.
RELATED: Antidepressant No Help to Heart Failure Patients
That's because the study didn't include a comparison group that did not receive stem cells.
So it's possible, Gorodeski explained, that the "modest" symptom improvements would have happened anyway. All of the patients were on standard medications, and some had heart devices implanted.
Stem cells are primitive cells that mature into the various cells that make up the body's tissues. In the past 15 years or so, scientists have tried to use the cells to help repair some of the damage seen in heart failure.
Heart failure is a progressive disease where the heart muscle is too damaged to efficiently pump blood throughout the body. It often arises after a heart attack.
Symptoms of heart failure include fatigue, breathlessness and swelling in the limbs. The condition cannot be cured, although medications and implantable devices can treat the symptoms.
In the new study, the researchers used stem cells from the patients' own thigh muscle to create a patch they placed on the heart.
That's in contrast to many past studies, where researchers have injected stem cells -- often from patients' bone marrow -- into the heart.
The patch tactic could have some advantages, said senior researcher Dr. Yoshiki Sawa, of Osaka University.
He said animal research suggests that cells in sheet form survive for a longer period, compared to injections.
To test the safety of the approach, Sawa's team recruited 27 patients who had debilitating symptoms despite standard heart failure therapies. The scientists extracted stem cells from each patient's thigh muscle, then cultured the cells so that they formed a sheet.
The sheet was placed on each patient's heart.
The tactic appeared safe, the researchers said, and there were signs of symptom improvements over the next six months to a year.
Why would stem cells from the thigh muscle affect the heart? It's not clear, Sawa acknowledged.
The stem cells don't grow into new heart muscle cells. Instead, Sawa explained, they seem to produce chemicals called cytokines that can promote new blood vessel growth in damaged areas of the heart. The theory, he said, is that "hibernating" cells in the heart muscle can then function better.
Still, it's too soon to know what the new findings mean, said Gorodeski.
This type of trial, called phase 1, is designed to look at the safety and feasibility of a therapy, Gorodeski said. It takes later-phase trials -- where some patients receive the treatment, and others do not -- to prove that a therapy actually works.
Those trials are underway, Sawa said.
Other studies are further along. Last year, researchers reported on a trial testing infusions of stem cells taken from the bone marrow of patients with severe heart failure.
Patients who received the therapy were less likely to die or be hospitalized over the next year, versus those given standard treatment only. But the study was small, and the stem cells had only a minor impact on patients' heart function.
So it's not clear why the stem-cell patients fared better, Gorodeski said.
For now, he stressed, all stem-cell therapies for heart failure remain experimental.
"There's no cell therapy that we can offer patients right now," Gorodeski said.
The message for patients, he added, is that heart failure can be treated, and researchers are looking for "innovative" ways to improve that treatment.
The study was published April 5 in theJournal of the American Heart Association.

Lungs of mice found to produce blood – The Manitoban
By daniellenierenberg
Home Science & Tech
By Malak Abason April 5, 2017
Lungs are a crucial organ in many animals, including humans. While their function has always seemed pretty straightforward to take in oxygen, transfer it into blood, and exhale carbon dioxide scientists have found a previously unrecognized function of the lungs of mice: blood production.
The study, which was published in Nature by researchers at the University of California San Francisco, was performed by inserting fluorescent protein into the mouses genome.
The protein caused the platelets (small blood cells that bind together to help create blood clots when a blood vessel is damaged), in the mouse to glow, allowing scientists to trace the platalets paths. What they found was a massive number of megakaryocytes, a stem cell that produces in the lungs.
When researched further, scientists found that the lung was producing over 10 million blood-producing platelets per hour, and the platelets produced by the lung accounted for the majority of platelets in the mouses circulatory system. Researchers are theorizing that the megakaryocytes are created in the bone marrow, but then travel to the lung to produce platelets.
While it is known that human lungs produce platelets and produce blood, as small amounts of megakaryocytes have been found in lungs before, if these findings are reproduced in humans, it will prove that the sheer amount that lungs produce has been greatly underestimated.
The study also found a reservoir of stem cells with the ability to become blood cells in the lungs. Researchers implanted lungs with the fluorescent megakaryocyte cells into mice that had been engineered to have no blood stem cells in their bone marrow, and found that the fluorescent cells travelled from the lungs to the marrow, and helped to produce platelets and other ingredients in blood, including neutrophils. In cases where the bone marrow is dealing with platelet or stem cell deficiency, these stem cells were able to leave the lung and contribute to the refilling of platelets in the marrow.
If further research indicates that these findings also apply to humans which they very well may, considering the genetic and biological similarities between mice and humans it will not only disprove the current theory that states the bone marrow accounts for most of the human bodys platelet production, but it will also affect how scientists approach treating blood diseases in humans, particularly ones that result in a platelet deficiency, such as thrombocytopenia.
New technique helps researchers determine how stem cells differentiate – Phys.Org
By daniellenierenberg
April 5, 2017
Stem cell differentiation can now be seen thanks to a combination of machine learning and microfabrication techniques developed by scientists at the RIKEN Quantitative Biology Center in Japan. The results, published in PLOS One, followed the differentiation of human mesenchymal stem cells (MSC) which are easily obtained from adult bone marrow.
MSCs have proven to be important for regenerative medicine and stem cell therapy because they can potentially repair many different types of organ damage, as they have the ability to differentiate into various cell types including bone, muscle and fat. Depending on the way the cells are grown the results can be quite different and so controlling differentiation is an important goal.
Observing MSC differentiation under different conditions is an essential step in understanding how to control the process. However, this has proved challenging on two fronts. First, the physical space in which the cells are grown has a dramatic impact on the results, causing significant variation in the types of cells into which they differentiate. Studying this effect requires consistent and long lasting spatial confinement. Second, classifying the cell types which have developed through manual observation is time consuming.
Previous studies have confined cell growth with fibronectin on a glass slide. The cells can only adhere and differentiate where the fibronectin is present and are thus chemically confined. However, this procedure requires high technical skill to maintain the confinement for an extended period of time. To overcome this, the first author of the study, Nobuyuki Tanaka, decided to look for a new way to confine them. Using a simple agarose gel physical confinement system, he found that he could maintain them for up to 15 days. Tanaka says, "It was wonderful to be able to do this, because agarose gel is a commonly used material in biology laboratories and can be easily formed into a micro-cast in a PDMS silicone mold."
He continues, "The advantage of this system is that once the PDMS molds are obtained the user only needs agarose gel and a vacuum desiccator to create highly reproducible micro-casts." The vacuum pump pulls the agarose gel into the mold. He explains, "We provided the protocol to our coauthors at ETH Zurich and they performed the agarose micro-casting and conducted the stem cell differentiation study. Stem cells were captured in the micro-structures and their differentiation was controlled under the captured condition."
Tanaka's paper also describes an automated cell type classification system, using machine learning, which reduces the time and labor needed to analyze cells. "Combined together, these tools give us a powerful way to understand how stem cells differentiate in given conditions."
According to Yo Tanaka, leader of the Laboratory for Integrated Biodevice, where the research was conducted, "We hope this will break down the barriers that have hindered research in this area so far and help to establish harmony between biologists and engineers. The focus of engineers has traditionally been to develop new technologies, but scientists prefer to use well established technologies. However, if our newly developed technology is simple enough it can spread rapidly, this is our goal."

Stem Cells Show Promise For Treating Autism – Disability Scoop
By daniellenierenberg
A small, but promising study suggests that stem cells from a childs own cord blood may offer an effective treatment for autism symptoms.
Most children on the spectrum who received an infusion from their own umbilical cord blood showed improvements in behavior, communication and socialization, among other measures, while experiencing no significant downsides from the treatment.
The findings come from a study of 25 kids with autism ages 2 to 5 published Wednesday in the journal Stem Cells Translational Medicine.

All of the children who participated in the research had their cord blood banked at birth. For the trial, the kids were given a series of behavioral and functional assessments before receiving a one-time cord blood infusion. Follow-up assessments were conducted at six and 12 months after the infusion.
Not only did the researchers find that the treatment was safe, but parent reports as well as clinical assessments indicated that more than two-thirds of the children saw improvements in autism symptoms.
Most of the behavioral gains were seen in the first six months after the infusion, the study found, but they were sustained over the following six months.
We are pleased that this study demonstrated the safety of treating children with ASD with their own cord blood, said Joanne Kurtzberg, a pediatric bone marrow transplant specialist at Duke Health who worked on the study. Were also encouraged that, while small and non-randomized, there were observed improvements in a majority of the children reported by clinicians and parents.
While the findings are encouraging, researchers said that further study involving more participants is needed before any firm conclusions can be reached about the effectiveness of cord blood infusions.
We are now hoping to replicate these preliminary results in a Phase II randomized clinical trial for which enrollment is nearly complete, Kurtzberg said.

I’m a woman of color with cancer. Here’s why I can’t find a bone … – KUOW News and Information
By daniellenierenberg
Alexes Harris tells KUOW's Katherine Banwell her story.
When ProfessorAlexes Harris learned she had a rare form of leukemia, she knew she was in a fight for her life. But she didn't realize how difficult it would be to find a bone marrow match as a woman of color. This is her story.
I have a rare blood cancer called myelodysplastic syndrome.
I was diagnosed in May 2016 after a year of various tests.Prior to being diagnosed, my only health complaints were a random onset of what felt like asthma attacks during my cycling classes (the only reason I went to the doctor), feeling very tired, and not always thinking clearly. I was told that if I did not begin treatment right away I would have two years to live.
Im a 41-year-old mother of a 9 year old and 5 year old (and wife to an amazing husband), so my only true option was to begin treatment.
After being presented with treatment options, we opted for an intensive round of in-patient chemotherapy, which I underwent in June 2016 and managed symptoms in July, 2016.During my initial diagnosis I learned that I would eventually need a bone marrow or stem cell transplant. This would be my only hope of a cure.
We immediately started research to learn about how matches were found and I discovered that because I am a person with a mixed race and ethnic background (African American, Filipino and white) I would have a difficult time finding a full donor match.
While whites have a 75 percent chance of finding a full match in the existing bone marrow registry, African Americans only have a 19 percent likelihood of finding a match. African Americans comprise only 7 percent of the United States registry.
And, it is projected that by 2017 our likelihood of finding a match will only raise to 21 percent. Within the United States registry, the likelihood for finding a full match is higher for people of Mexican (37 percent), Chinese (41 percent), South Asian (33 percent), Hispanic Caribbean (40 percent) and Native American (52 percent) ancestry than for African Americans, but still significantly lower than the likelihood for whites.
Finding a non-related full match is difficult if you are a person of color, especially people of mixed race origin. Having a 100 percent match is crucial in predicting positive outcomes post-transplant. While the Seattle Cancer Care Alliance has been searching for a match, today, I still do not have a full bone marrow donor match and am moving forward with an alternative stem cell transplant using donated umbilical cord blood. My transplant for using cord blood was in September.
This is why we are organizing a national bone marrow donation registry campaign.I want to make my cancer matter, so my great friends stepped in to make this happen. Our goal is to have 4,000 new people registered by this effort. We need people of all backgrounds to become potential matches to help people like me live.
I am a professor of sociology and teach about social stratification, inequality and racial outcomes in institutional processing.I research class and racial differences in criminal justice processing and outcomes. I am the daughter of a black and Filipino man, wife to a black man, sister to black men, and mother of a black son and daughter.I live in the United States and, as many of us know, understand the racial inequalities in our broader society.Many times I feel overwhelmed about the lack of ability to make institutional differences, be it in our systems of education, criminal justice and health care.
Yet, when it comes to bone marrow donation, and other blood products and organ donation, we can make a difference. We can, for ourselves, save ourselves. Becoming involved in donation empowers us in a way like no other to alleviate health care disparities.
You can learn a lot about my story and this campaignatteamalexes.com. We had bone marrow registries in five cities last fall Seattle, Los Angeles, Houston, Washington, D.C., and New York.
Please consider signing up for the bone marrow registry. You can literally be a superhero and save someones life.
Dr. Alexes Harris is a professor of sociology at the University of Washington. This essay was originally published on her personal website.

How Adult Stem Cell Therapy Is Breaking Glass Ceiling Of Modern Medicine – Leadership Newspapers
By daniellenierenberg
It offers hope for sufferers of diseases hitherto thought incurable
Adult Stem Cell Therapy has gained popularity in developed countries as an alternative to the conventional treatment of many diseases. There are several studies and clinical trials conducted in the United States to support this.
Some current line of treatments are not typically effective, and some can cause detrimental side effects. Medicine is evolving to a more natural and more effective means with the use of stem cells. Due to the numerous religious and ethical issues that comes with the use of embryonic stem cells, todays medicine is moving towards the application of Adult Stem Cell Therapy. This article highlights some new applications of adult stem cells in conditions and diseases that has posed a problem in our society for far too long.
Sickle Cell Anemia
Tissue-based treatments is already evident in the United States of America. In 2012, a patient was successfully cured of sickle cell disease after receiving achemotherapy-free stem cell transplant for sickle cell disease. Additional patients have been successfully treated since then. Two studies conducted in 2014 and 2015 have shown that the use of adult stem cell therapy can greatly reduce complications or even stop the progression of the diseases by providing stem cells to the needed areas. This reduces the need for surgeries for many of these patients.
Diabetes
According to International Diabetes Federation (IDF), there were over 40,000 deaths due to diabetes documented in Nigeria in 2015. Treatment for diabetes has been a focal point for medical research for many years. Consequently, some studies and clinical trials conducted have shown that Adult Adipose (fat) Stem Cell Transplantation can lower and regulate sugar levels resulting in reducing or eliminating the amount of medication or insulin that patients need to take.
In a recently conducted clinical trial, some of the patients achieved insulin independence that remained stable for a median time of 29 months, and another patient for 43 months ongoing. In fact, all the patients studied showed substantial improvement in their dependence on insulin and overall diabetic condition.
Sexual Dysfunction
The emergence of Regenerative Medicine (which includes Adult Stem Cell and Platelet Rich Plasma therapy) has positively impacted the sexual life of both women (O-Shot) and men (P-Shot), and the treatment is also being used for urinary incontinence, etc. There is now ample evidence to show that O-Shot helps women increase their sexual responses, the ability to have Vaginal Orgasm, arousal from clitoral stimulation, sexual desire and natural lubrication, arousal from G-spot stimulation, as well as decrease pain during intercourse and tighten vaginal opening.
Furthermore, P-Shotin men regenerates damaged penile tissues faster and stronger than most traditional treatments. In most cases, treated men see increase in length up to 1 inch or more and girth up to 3/4 inch or more while also increasing their sexual stamina.
Arthritis
Adult stem cells transplantationhas also been studied in arthritis, and there has been some positive reports about its efficacy. In 2014, the effects of stem cells for articular cartilage regeneration was studied.They studied the effect of stem cells injection in treating osteoarthritis of the knee, and the results showed significant improvement.
Neurological Disorders (e.g. Spinal Cord Injury)
The usefulness of stem cell therapy in neurological disorders like Multiple Sclerosis, Cerebral Palsy, Spinal Cord Injury, etc. has been shown in different studies and clinical trials. The prognosis for spinal cord injuries is generally believed to be poor. However, recent researches and case studies are changing this ideology as the value of adult stem cell therapy for patients with spinal cord injuries is emerging.
An example of this can be seen in a case study published in 2015. In this case study, a patient with functional loss below the lesion level due to a motor vehicle accident failed standard therapy but saw clinically meaningful improvements after multiple adult stem cell treatments. Stem cell transplantations over a period of months led to the restoration of the patients ability to move lower extremities against gravity, control the body trunk, and the ability to control the bladder. The patient was also able to stand as well as walk with the aid of hip and knee ortheses. The sensation level also increased.
Conclusion
Regenerative medicine involving adult stem cells is continually being studied and researched to gather more evidence to enable harnessing its clinical potentials. The use of adult stem cells for clinical therapy is now a reality for many patients who were not able to shed the yoke of many diseases that conventional medicine provided very little hope of permanent relief for.
One new innovation is the Umbilical Cord Stem Cells transplantation that is now done without the need for HLA matching. This allows anyone to be treated for conditions or diseases where applicable. In case of sickle cell disease, case studies have been published on the use of Umbilical Cord Stem Cells from HLA matching donors to remedy sickle cell disease; however, case studies are yet to be published on the efficacy of the Umbilical Cord Stem Cells not requiring HLA matching for the treatment of sickle cell disease. I am cautious to note that the results may differ from case to case, so not every sickle cell patient will be a good candidate for the treatment.
Currently, Adult Stem Cell Therapy is now seen as a viable therapeutic alternative for joint and back pain, sexual dysfunction, diabetes, End Stage Renal Disease on hemodialysis, arthritis, etc. The treatments are gaining popularity among patients and doctors because it is natural and can help repair and regenerate most parts of the human tissues.

VistaGen Therapeutics Receives European Patent Office Notice of Intention to Grant European Patent for AV-101 – Yahoo Finance
By daniellenierenberg
SOUTH SAN FRANCISCO, CA--(Marketwired - March 29, 2017) - VistaGen Therapeutics Inc. (VTGN), a clinical-stage biopharmaceutical company focused on developing new generation medicines for depression and other central nervous system (CNS) disorders, announced today that the European Patent Office (EPO) has issued a Notice of Intention to Grant the Company's European Patent Application for AV-101, its oral CNS prodrug candidate in Phase 2 development for major depressive disorder (MDD). The granted claims covering multiple dosage forms of AV-101, treatment of depression and reduction of dyskinesias associated with L-DOPA treatment of Parkinson's disease will be in effect until at least January 2034.
"We are extremely pleased to receive the EPO's notice of intention to grant significant CNS-related patent claims for AV-101, another substantial step forward in our plan to secure a broad spectrum of intellectual property protection for AV-101 covering multiple CNS indications," stated Shawn Singh, Chief Executive Officer of VistaGen.
About AV-101
AV-101 (4-CI-KYN) is an oral CNS prodrug candidate in Phase 2 development in the U.S. as a new generation treatment for major depressive disorder (MDD). AV-101 also has broad potential utility in several other CNS disorders, including chronic neuropathic pain and epilepsy, as well as neurodegenerative diseases, such as Parkinson's disease and Huntington's disease.
AV-101 is currently being evaluated in a Phase 2 monotherapy study in MDD, a study being fully funded by the U.S. National Institute of Mental Health (NIMH) and conducted by Dr. Carlos Zarate Jr., Chief, Section on the Neurobiology and Treatment of Mood Disorders and Chief of Experimental Therapeutics and Pathophysiology Branch at the NIMH, as Principal Investigator.
VistaGen is preparing to advance AV-101 into a 180-patient, U.S. multi-center, Phase 2 adjunctive treatment study in MDD patients with an inadequate response to standard FDA-approved antidepressants, with Dr. Maurizio Fava of Harvard University as Principal Investigator.
About VistaGen
VistaGen Therapeutics, Inc. (VTGN), is a clinical-stage biopharmaceutical company focused on developing new generation medicines for depression and other central nervous system (CNS) disorders. VistaGen's lead CNS product candidate, AV-101, is a new generation oral antidepressant drug candidate in Phase 2 development for major depressive disorder (MDD). AV-101's mechanism of action is fundamentally differentiated from all FDA-approved antidepressants and atypical antipsychotics used adjunctively to treat MDD, with potential to drive a paradigm shift towards a new generation of safer and faster-acting antidepressants. AV-101 is currently being evaluated by the U.S. National Institute of Mental Health (NIMH) in a Phase 2 monotherapy study in MDD being fully funded by the NIMH and conducted by Dr. Carlos Zarate Jr., Chief, Section on the Neurobiology and Treatment of Mood Disorders and Chief of Experimental Therapeutics and Pathophysiology Branch at the NIMH. VistaGen is preparing to launch a 180-patient Phase 2 study of AV-101 as an adjunctive treatment for MDD patients with inadequate response to standard, FDA-approved antidepressants. Dr. Maurizio Fava of Harvard University will be the Principal Investigator of the Company's Phase 2 adjunctive treatment study. AV-101 may also have the potential to treat multiple CNS disorders and neurodegenerative diseases in addition to MDD, including chronic neuropathic pain, epilepsy, Parkinson's disease and Huntington's disease, where modulation of the NMDAR, AMPA pathway and/or key active metabolites of AV-101 may achieve therapeutic benefit.
VistaStem Therapeutics is VistaGen's wholly owned subsidiary focused on applying human pluripotent stem cell technology, internally and with collaborators, to discover, rescue, develop and commercialize proprietary new chemical entities (NCEs), including small molecule NCEs with regenerative potential, for CNS and other diseases, and cellular therapies involving stem cell-derived blood, cartilage, heart and liver cells. In December 2016, VistaGen exclusively sublicensed to BlueRock Therapeutics LP, a next generation regenerative medicine company established by Bayer AG and Versant Ventures, rights to certain proprietary technologies relating to the production of cardiac stem cells for the treatment of heart disease.

A Japanese Man Has Become the First Recipient of Donated … – Futurism
By daniellenierenberg
In Brief A Japanese man has become the first recipient of donated, reprogrammed stem cells as a treatment for macular degeneration. If the treatment proves effective against the age-related eye condition, it could halt or prevent the vision loss of the 10 million people in the U.S. who have macular degeneration. A New Treatment for Macular Degeneration
Macular degeneration is the leading cause of progressive vision loss with almost 10million Americans affected by the disease. Currently, there are no known cures for the conditionalthough stem cells might change that entirely.
Macular degeneration occurs when the central portion, the macula, of the retina is deteriorated. This is where our eyes record images and send them to the brain through the optic nerve. The macula is known for focusing our vision, controlling our ability to read, recognize faces, and see objects clearly.
A Japaneseman in his sixties is the worlds first person to receive induced pluripotent stem (iPS) cells donated by a different individual. Rather than tip-toeing around the ethics of embryonic stem cells, scientists were able to remove mature cells from a donor and reprogram them into an embryonic state, which then could be developed into a specific cell-type to treat the disease. Physicians cultivated donated skin cells that were transplanted onto the mans retina to halt the progression of his age-related macular degeneration.
While the mans first surgery was a success, the doctors have said they will make no more announcements about his progress until they have completed all five of the planned procedures. While the effectiveness of this technique cannot be evaluated until the fate of the donated cells and the progression of the patientsmacular degenerationhave been fully monitored, there is increasing interest inusing iPScells for theraputic purposes.
A similar therapy was performed at the Kobe City Medical Center General Hospital in Japan in September 2014, but with a slight difference. In this case, the patient received her own skin cells reprogrammed into retinal cells. As hoped, a year after the surgery her vision had no decline, seemingly halting the macular degeneration. Four more patients in the clinical trial are expected to receive donor cells as well.
The donor-cell procedure, if successful, could help pave the way for the iPS cell bank thatShinya Yamanaka is establishing. An iPS cell bank would allow physicians find theperfect iPS donor per each patients biological signatures. Yamanaka is a Nobel-prizewinning scientist at Kyoto University who pioneered the iPS cells.
Yamanakas idea of a iPS cell bank has the potential torevolutionize modern medicine. It would provide patients with ready-made cells immediately, givinga widespread population access to more treatment options bylower all-around costs. While the risk of genetic defects or a poor donor match still remains, the new procedurecould offer enormous advantagescompared toother alternatives.

Lifesaving donor needed for TV debt collector Delroy – The Voice Online
By daniellenierenberg

APPEAL: Delroy Anglin, star of TV's 'Cant' Pay? We'll Take it Away!' (photo credit: DCBL)
DELROY ANGLIN, a star bailiff of the TV series, 'Cant Pay? Well Take it Away!' has launched an appeal to encourage more African and Caribbean people living in the UK to join the Stem Cell Register.
The #Match4Delroy appeal which is to be led by blood cancer charity, the African Caribbean Leukaemia Trust (ACLT) is hoping to find an unmatched donor for Delroy who requires a lifesaving stem cell, specifically, a bone marrow transplant if he is to beat his battle with leukaemia.
Delroy, aged 56, was diagnosed with Acute Myeloid Leukaemia (AML) last November. Since his diagnosis, Delroy has managed with drugs and receiving two rounds of chemotherapy, but tests show the leukaemia remains. Doctors have confirmed Delroy will need an urgent stem cell transplant to beat the illness.
With siblings having a one in four chance of being a match, it was no surprise out of Delroys five siblings, none were found to be a match to help their brother.
The pain and anguish of dealing with a loved one being diagnosed with blood cancer is something Delroy and his family are all too familiar with, as it was 40 years ago, Delroys brother lost his battle against leukaemia which makes Delroys illness that much more painful for his loved ones to deal with.
Delroys sister Janet Hills, who is Chair at the Met Black Police Association (MBPS) and President at National Black Police Association, or NBPA, said:
When I tell people that Delroy from Cant Pay? Well Take it Away! is my brother, there is an immediate outpouring of warmth and love. I'm praying this appeal turns that love into action. FAMILY: Janet Hills of the Met Black Police Association and Delroy Anglin's sister (photo credit: David Sillitoe/The Guardian) ACLT is the preferred charity for the MBPS and the NBPA. Our members continually engage with the charity and organise community events to raise awareness and funds. If you love Del on the show as much as I love him as my brother, then please, please, please make that commitment today to join the stem cells (bone marrow) register.
Delroy is being supported by his loving family which includes his children and mother. His daughter Domenique Anglin said:
Dad is an active, charismatic person, he loves socialising with his family and friends. He is a fantastic father to my siblings and a wonderful grandfather too. I am appealing on his behalf to all Caribbean and African people in the UK and abroad to join the register, in the hope they might be the match that saves his life.
Anglin said:
Its going to be difficult to find me a perfect matched donor unless we have a lot more Caribbean and African people on the register. It takes 15 minutes to register and is almost painless to donate. I want to beat this illness, but I will only be able to do so, with the help of the Caribbean and African community.

Cellects technology, ApoGraft, aims to become a game changerin stem cells transplantations for cancer treatments
Company gets green light from DSMB Board for enrolling additional 2 cancer patients for ApoGraft transplantation treatments
TEL AVIV, Israel, March 27, 2017 (GLOBE NEWSWIRE) -- Cellect Biotechnology Ltd. (Nasdaq:APOP) (TASE:APOP), a developer of stem cell selection technology, announced today that the first stem cell transplant procedure has been successfully performed using its ApoGraft technology in the Companys Phase I/II clinical trial in a blood cancer patient.
Up to 50 percent of stem cell transplant procedures, such as bone marrow transplants, result in life-threatening rejection disease, known as Graft-versus-Host-Disease (GvHD). Cellects ApoGraft technology is aiming to turn stem cell transplants into a simple, safe and cost effective process, reducing the associated severe side effects, such as rejection and many other risks.
Dr. Shai Yarkoni, Cellects CEO said, After 15 years of research, this is the first time we have used our technology on a cancer patient suffering from life-threatening conditions. It is a first good step on a road that we hope will lead to stem cell based regenerative medicine becoming a safe commodity treatment at every hospital in the world.
Based on the successful transplantation results, the independent Data and Safety Monitoring Board (DSMB) approved the enrollment of 2 additional patients for ApoGraft treatment to complete the first study cohort as planned.
About GvHD
Despite improved prophylactic regimens, acute GvHD disease still occurs in 25% to 50% of recipients of allogeneic stem cell transplantation. The incidence of GvHD in recipients of allogeneic stem cells transplantation is increasing due to the increased number of allogeneic transplantations survivors, older recipient age, use of alternative donor grafts and use of peripheral blood stem cells. GvHD accounts for 15% of deaths after allogeneic stem cell transplantation and is considered the leading cause of non-relapse mortality after allogeneic stem cell transplantation.
About ApoGraft01 study
The ApoGraft01 study (Clinicaltrails.gov identifier: NCT02828878), is an open label, staggered four-cohort, Phase I/II, safety and proof-of-concept study of ApoGraft process in the prevention of acute GvHD. The study, which will enroll 12 patients, aims to evaluate the safety, tolerability and efficacy of the ApoGraft process in patients suffering from hematological malignancies undergoing allogeneic stem cell transplantation from a matched related donor.

Stem cell centre coming to Kamloops? – CFJC Today Kamloops
By daniellenierenberg
KAMLOOPS My curiosity was sparked when I read that a stem cell centre was opening in Kamloops (Kamloops This Week, March 21, 2017).
So I went to the location of the centre at 470 Columbia St only to find a parking lot. Thinking that the address might be wrong, I searched the directory of the medical building next door and found that no stem cell centre was listed.
The Stem Cell Centers website lists Kamloops as the only one in Canada. Dr. Richard Brownlee is named as the surgeon with more information coming soon.
Stem cell therapy, says the website, can help with orthopedic or pain management, ophthalmological conditions, cardiac or pulmonary conditions, neurological conditions, and auto-immune diseases, among many other conditions and disease that results in damaged tissue.
One of the ophthalmological conditions they treat is macular degeneration. If your vision is fading due to macular degeneration, you know its time to seek help. Our non-invasive Stem Cell Therapy treatment might be the solution for you.
I wanted get Dr. Brownlees reaction to news that an unproven stem cell treatment had resulted in blindness according to the New England Journal of Medicine as reported in the Globe and Mail, March 20, 2017.
This week, the New England Journal of Medicine (NEJM) reported on three individuals who went blind after receiving an unproven stem cell treatment at a Florida clinic. The patients paid thousands of dollars for what they thought was a clinical trial on the use of stem cells to treat macular degeneration.
The writer of the Globe and Mail article, Timothy Caulfield, Research Chair of the in Health Law and Policy at the University of Alberta, doesnt name the Florida clinic.
The Stem Cell Centers website refers optimistically to treatment for macular degeneration at a Florida clinic, although apparently not theirs since no Florida clinic appears on their list. It tells of how Doug Oliver suffered from macular degeneration before stem cells were extracted from his hip bone and injected them into his eyes. Almost immediately, Olivers eyesight started to improve. I began weeping, he said.
Caulfield encourages caution. Health science gets a lot of attention in the popular press. People love hearing about breakthroughs, paradigm shifts and emerging cures. The problem is, these stories are almost always misleading. It can also help to legitimize the marketing of unproven therapies.
Reports from the Stem Cell Centers own website are cautionary as well. It quotes an abstract from a study done by the Southern California College of Optometry on how stem cells might ultimately be used to restore the entire visual pathway.
The promise of stem cell research is phenomenal. Scientific American (Jan., 2017) reports that brains can be grown in a lab dish from stem cells taken from skin. These samples can be used to research brain disorders ranging from schizophrenia to Alzheimer's disease, and to explore why only some babies develop brain-shrinking microcephaly after exposure to the Zika virus.
However, Dr. George Daley, dean of Harvard Medical School, concludes that there are only a handful of clinical applications available and they are for skin and blood-related ailments.
Practice, it seems, has not yet matched the promise of stem cell research.

By daniellenierenberg
Stem cells are undifferentiated biological cells that can differentiate into specialized cells and can divide (through mitosis) to produce more stem cells. They are found in multicellular organisms. In mammals, there are two broad types of stem cells: embryonic stem cells, which are isolated from the inner cell mass of blastocysts, and adult stem cells, which are found in various tissues. In adult organisms, stem cells and progenitor cells act as a repair system for the body, replenishing adult tissues. In a developing embryo, stem cells can differentiate into all the specialized cellsectoderm, endoderm and mesoderm (see induced pluripotent stem cells)but also maintain the normal turnover of regenerative organs, such as blood, skin, or intestinal tissues.
There are three known accessible sources of autologous adult stem cells in humans:
Stem cells can also be taken from umbilical cord blood just after birth. Of all stem cell types, autologous harvesting involves the least risk. By definition, autologous cells are obtained from ones own body, just as one may bank his or her own blood for elective surgical procedures.
Adult stem cells are frequently used in medical therapies, for example in bone marrow transplantation. Stem cells can now be artificially grown and transformed (differentiated) into specialized cell types with characteristics consistent with cells of various tissues such as muscles or nerves. Embryonic cell lines and autologous embryonic stem cells generated through Somatic-cell nuclear transfer or dedifferentiation have also been proposed as promising candidates for future therapies.[1] Research into stem cells grew out of findings by Ernest A. McCulloch and James E. Till at the University of Toronto in the 1960s.[2][3]
The classical definition of a stem cell requires that it possess two properties:
Two mechanisms exist to ensure that a stem cell population is maintained:
Potency specifies the differentiation potential (the potential to differentiate into different cell types) of the stem cell.[4]
In practice, stem cells are identified by whether they can regenerate tissue. For example, the defining test for bone marrow or hematopoietic stem cells (HSCs) is the ability to transplant the cells and save an individual without HSCs. This demonstrates that the cells can produce new blood cells over a long term. It should also be possible to isolate stem cells from the transplanted individual, which can themselves be transplanted into another individual without HSCs, demonstrating that the stem cell was able to self-renew.
Properties of stem cells can be illustrated in vitro, using methods such as clonogenic assays, in which single cells are assessed for their ability to differentiate and self-renew.[7][8] Stem cells can also be isolated by their possession of a distinctive set of cell surface markers. However, in vitro culture conditions can alter the behavior of cells, making it unclear whether the cells will behave in a similar manner in vivo. There is considerable debate as to whether some proposed adult cell populations are truly stem cells.
Embryonic stem (ES) cells are stem cells derived from the inner cell mass of a blastocyst, an early-stage embryo.[9] Human embryos reach the blastocyst stage 45 days post fertilization, at which time they consist of 50150 cells. ES cells are pluripotent and give rise during development to all derivatives of the three primary germ layers: ectoderm, endoderm and mesoderm. In other words, they can develop into each of the more than 200 cell types of the adult body when given sufficient and necessary stimulation for a specific cell type. They do not contribute to the extra-embryonic membranes or the placenta.
Nearly all research to date has made use of mouse embryonic stem cells (mES) or human embryonic stem cells (hES). Both have the essential stem cell characteristics, yet they require very different environments in order to maintain an undifferentiated state. Mouse ES cells are grown on a layer of gelatin as an extracellular matrix (for support) and require the presence of leukemia inhibitory factor (LIF). Human ES cells are grown on a feeder layer of mouse embryonic fibroblasts (MEFs) and require the presence of basic fibroblast growth factor (bFGF or FGF-2).[10] Without optimal culture conditions or genetic manipulation,[11] embryonic stem cells will rapidly differentiate.
A human embryonic stem cell is also defined by the expression of several transcription factors and cell surface proteins. The transcription factors Oct-4, Nanog, and Sox2 form the core regulatory network that ensures the suppression of genes that lead to differentiation and the maintenance of pluripotency.[12] The cell surface antigens most commonly used to identify hES cells are the glycolipids stage specific embryonic antigen 3 and 4 and the keratan sulfate antigens Tra-1-60 and Tra-1-81. The molecular definition of a stem cell includes many more proteins and continues to be a topic of research.[13]
There are currently no approved treatments using embryonic stem cells. The first human trial was approved by the US Food and Drug Administration in January 2009.[14] However, the human trial was not initiated until October 13, 2010 in Atlanta for spinal injury victims. On November 14, 2011 the company conducting the trial announced that it will discontinue further development of its stem cell programs.[15] ES cells, being pluripotent cells, require specific signals for correct differentiationif injected directly into another body, ES cells will differentiate into many different types of cells, causing a teratoma. Differentiating ES cells into usable cells while avoiding transplant rejection are just a few of the hurdles that embryonic stem cell researchers still face.[16] Many nations currently have moratoria on either ES cell research or the production of new ES cell lines. Because of their combined abilities of unlimited expansion and pluripotency, embryonic stem cells remain a theoretically potential source for regenerative medicine and tissue replacement after injury or disease.

The primitive stem cells located in the organs of fetuses are referred to as fetal stem cells.[17] There are two types of fetal stem cells:
Adult stem cells, also called somatic (from Greek , of the body) stem cells, are stem cells which maintain and repair the tissue in which they are found.[19] They can be found in children, as well as adults.[20]
Pluripotent adult stem cells are rare and generally small in number, but they can be found in umbilical cord blood and other tissues.[21] Bone marrow is a rich source of adult stem cells,[22] which have been used in treating several conditions including spinal cord injury,[23] liver cirrhosis,[24] chronic limb ischemia [25] and endstage heart failure.[26] The quantity of bone marrow stem cells declines with age and is greater in males than females during reproductive years.[27] Much adult stem cell research to date has aimed to characterize their potency and self-renewal capabilities.[28] DNA damage accumulates with age in both stem cells and the cells that comprise the stem cell environment. This accumulation is considered to be responsible, at least in part, for increasing stem cell dysfunction with aging (see DNA damage theory of aging).[29]
Most adult stem cells are lineage-restricted (multipotent) and are generally referred to by their tissue origin (mesenchymal stem cell, adipose-derived stem cell, endothelial stem cell, dental pulp stem cell, etc.).[30][31]
Adult stem cell treatments have been successfully used for many years to treat leukemia and related bone/blood cancers through bone marrow transplants.[32] Adult stem cells are also used in veterinary medicine to treat tendon and ligament injuries in horses.[33]
The use of adult stem cells in research and therapy is not as controversial as the use of embryonic stem cells, because the production of adult stem cells does not require the destruction of an embryo. Additionally, in instances where adult stem cells are obtained from the intended recipient (an autograft), the risk of rejection is essentially non-existent. Consequently, more US government funding is being provided for adult stem cell research.[34]
Multipotent stem cells are also found in amniotic fluid. These stem cells are very active, expand extensively without feeders and are not tumorigenic. Amniotic stem cells are multipotent and can differentiate in cells of adipogenic, osteogenic, myogenic, endothelial, hepatic and also neuronal lines.[35] Amniotic stem cells are a topic of active research.
Use of stem cells from amniotic fluid overcomes the ethical objections to using human embryos as a source of cells. Roman Catholic teaching forbids the use of embryonic stem cells in experimentation; accordingly, the Vatican newspaper Osservatore Romano called amniotic stem cells the future of medicine.[36]
It is possible to collect amniotic stem cells for donors or for autologuous use: the first US amniotic stem cells bank [37][38] was opened in 2009 in Medford, MA, by Biocell Center Corporation[39][40][41] and collaborates with various hospitals and universities all over the world.[42]
These are not adult stem cells, but rather adult cells (e.g. epithelial cells) reprogrammed to give rise to pluripotent capabilities. Using genetic reprogramming with protein transcription factors, pluripotent stem cells equivalent to embryonic stem cells have been derived from human adult skin tissue.[43][44][45]Shinya Yamanaka and his colleagues at Kyoto University used the transcription factors Oct3/4, Sox2, c-Myc, and Klf4[43] in their experiments on cells from human faces. Junying Yu, James Thomson, and their colleagues at the University of WisconsinMadison used a different set of factors, Oct4, Sox2, Nanog and Lin28,[43] and carried out their experiments using cells from human foreskin.
As a result of the success of these experiments, Ian Wilmut, who helped create the first cloned animal Dolly the Sheep, has announced that he will abandon somatic cell nuclear transfer as an avenue of research.[46]
Frozen blood samples can be used as a source of induced pluripotent stem cells, opening a new avenue for obtaining the valued cells.[47]
To ensure self-renewal, stem cells undergo two types of cell division (see Stem cell division and differentiation diagram). Symmetric division gives rise to two identical daughter cells both endowed with stem cell properties. Asymmetric division, on the other hand, produces only one stem cell and a progenitor cell with limited self-renewal potential. Progenitors can go through several rounds of cell division before terminally differentiating into a mature cell. It is possible that the molecular distinction between symmetric and asymmetric divisions lies in differential segregation of cell membrane proteins (such as receptors) between the daughter cells.[48]
An alternative theory is that stem cells remain undifferentiated due to environmental cues in their particular niche. Stem cells differentiate when they leave that niche or no longer receive those signals. Studies in Drosophila germarium have identified the signals decapentaplegic and adherens junctions that prevent germarium stem cells from differentiating.[49][50]
Diseases and conditions where stem cell treatment is being investigated include:
Stem cell therapy is the use of stem cells to treat or prevent a disease or condition. Bone marrow transplant is a crude form of stem cell therapy that has been used clinically for many years without controversy. No stem cell therapies other than bone marrow transplant are widely used.[64][65]
Research is underway to develop various sources for stem cells, and to apply stem cell treatments for neurodegenerative diseases and conditions, diabetes, heart disease, and other conditions.[66]
In more recent years, with the ability of scientists to isolate and culture embryonic stem cells, and with scientists growing ability to create stem cells using somatic cell nuclear transfer and techniques to created induced pluripotent stem cells, controversy has crept in, both related to abortion politics and to human cloning.
Stem cell treatments may require immunosuppression because of a requirement for radiation before the transplant to remove the patients previous cells, or because the patients immune system may target the stem cells. One approach to avoid the second possibility is to use stem cells from the same patient who is being treated.
Pluripotency in certain stem cells could also make it difficult to obtain a specific cell type. It is also difficult to obtain the exact cell type needed, because not all cells in a population differentiate uniformly. Undifferentiated cells can create tissues other than desired types.[67]
Some stem cells form tumors after transplantation; pluripotency is linked to tumor formation especially in embryonic stem cells, fetal proper stem cells, induced pluripotent stem cells. Fetal proper stem cells form tumors despite multipotency.[citation needed]
Hepatotoxicity and drug-induced liver injury account for a substantial number of failures of new drugs in development and market withdrawal, highlighting the need for screening assays such as stem cell-derived hepatocyte-like cells, that are capable of detecting toxicity early in the drug development process.[68]
Some of the fundamental patents covering human embryonic stem cells are owned by the Wisconsin Alumni Research Foundation (WARF) they are patents 5,843,780, 6,200,806, and 7,029,913 invented by James A. Thomson. WARF does not enforce these patents against academic scientists, but does enforce them against companies.[69]
In 2006, a request for the US Patent and Trademark Office (USPTO) to re-examine the three patents was filed by the Public Patent Foundation on behalf of its client, the non-profit patent-watchdog group Consumer Watchdog (formerly the Foundation for Taxpayer and Consumer Rights).[69] In the re-examination process, which involves several rounds of discussion between the USTPO and the parties, the USPTO initially agreed with Consumer Watchdog and rejected all the claims in all three patents,[70] however in response, WARF amended the claims of all three patents to make them more narrow, and in 2008 the USPTO found the amended claims in all three patents to be patentable. The decision on one of the patents (7,029,913) was appealable, while the decisions on the other two were not.[71][72] Consumer Watchdog appealed the granting of the 913 patent to the USTPOs Board of Patent Appeals and Interferences (BPAI) which granted the appeal, and in 2010 the BPAI decided that the amended claims of the 913 patent were not patentable.[73] However, WARF was able to re-open prosecution of the case and did so, amending the claims of the 913 patent again to make them more narrow, and in January 2013 the amended claims were allowed.[74]
In July 2013, Consumer Watchdog announced that it would appeal the decision to allow the claims of the 913 patent to the US Court of Appeals for the Federal Circuit (CAFC), the federal appeals court that hears patent cases.[75] At a hearing in December 2013, the CAFC raised the question of whether Consumer Watchdog had legal standing to appeal; the case could not proceed until that issue was resolved.[76]

$50 million gift to Packard Children’s Hospital will advance care … – Stanford Medical Center Report
By daniellenierenberg
Next wave of innovation and discovery
Over the past 70 years, new surgical techniques and medical therapies, some of which were developed at the Stanford School of Medicine and Packard Childrens, have evolved and greatly improved outcomes for children with almost every type ofcongenital heart disease.
Heart defects that were once universally fatal can now be surgically improved. As patients born with heart disease survive longer, there are now more adults than children in the United States with congenital heart disease. However, further advancements are still needed to ensure a healthier future for patients, many of whom continue to face a compromised quality of life and require subsequent surgeries.
Surgical intervention can repair, but it rarely can truly cure, said pediatric heart surgeonFrank Hanley, MD, who is also the Lawrence Crowley, MD, Endowed Professor in Child Health at the School of Medicine and executive director of the Betty Irene Moore Childrens Heart Center. Children who have received complex surgical intervention to repair a cardiac abnormality require careful monitoring and specialized care throughout their life span. We imagine a day when a child born with a poorly working aortic valve, rather than undergoing multiple open-heart operations throughout his lifetime, instead receives a replacement valve engineered from his own stem cells. Dr. and Mrs. Moores gift comes at a critical juncture enabling us to advance beyond surgical repair to the discovery of transformational treatments and interventions and, ultimately, to true cures.
The center has an overall survival rate of 98 percent. Beyond survival alone, the goal is now to ensure an excellent overall outcome from normal brain function for even the most fragile patients, to the ability for children to perform well in school and to exercise and enjoy an active life into adulthood.
We are committed to providingbabies and children with heart disease and their families with the happiest, healthiest lives possible, from the early identification of problems, to expert intervention, and finally to a lifetime of care and support, saidStephen Roth, MD, MPH, chief of pediatriccardiologyand director of the Betty Irene Moore Childrens Heart Center.
Dr. and Mrs. Moores incredible gift will not only bolster our clinical capabilities for children and families receiving care now in the Betty Irene Moore Childrens Heart Center, it will also accelerate basic and translational research by Stanford Medicine faculty and scientists to develop more precise techniques to predict, prevent and cure, said Lloyd Minor, MD, dean of the School of Medicine. When it comes to achieving precision health, we must think as big as we can not just about treating disease, but about making and keeping people healthy and nowhere is this more true than in children.
In 2017, Packard Childrens will complete its major expansion, becoming the most technologically advanced, family-friendly and environmentally sustainable childrens hospital in the nation. The Moores gift will enable the Childrens Heart Center to expand its state-of-the-art clinical and research facilities, train the future leaders of cardiovascular medicine and surgery, and improve the field of pediatric cardiology and pediatric cardiovascular surgery through innovative research. In addition, the center will expand its clinical facilities, including a newly designed outpatient center.
Packard Childrens established the Childrens Heart Center in 2001 to focus more expertise and resources on congenital heart disease, the most common type of birth defect worldwide. Each year, approximately 40,000 children in the United States are born with heart defects, and an additional 25,000 children develop some kind of acquired heart disease.
The center has gained recognition as a national and international destination program for several highly specialized surgical procedures, and is also a full-service cardiology program that cares for patients with all forms of cardiovascular conditions. Under the leadership of Hanley and Roth, the center receives more than 25,000 patient visits annually and performs 80 to 90 percent of all cardiac surgical care for children in northern and central California.

Pioneering stem cell gene therapy cures infants with bubble baby disease – UCLA Newsroom
By daniellenierenberg
FINDINGS
UCLA researchers have developed a stem cell gene therapy cure for babies born with adenosine deaminase-deficient severe combined immunodeficiency, a rare and life-threatening condition that can be fatal within the first year of life if left untreated.
In a phase 2 clinical trial led by Dr. Donald Kohn of theEli and Edythe Broad Center of Regenerative Medicine and Stem Cell Researchat UCLA, all nine babies were cured. A 10th trial participant was a teenager at the time of treatment and showed no signs of immune system recovery. Kohns treatment method, a stem cell gene therapy that safely restores immune systems in babies with the immunodeficiency using the childs own cells, has cured 30 out of 30 babies during the course of several clinical trials.
Adenosine deaminase-deficient severe combined immunodeficiency, also known as ADA-SCID or bubble baby disease, is caused by a genetic mutation that results in the lack of the adenosine deaminase enzyme, which is an important component of the immune system. Without the enzyme, immune cells are not able to fight infections. Children with the disease must remain isolated in clean and germ-free environments to avoid exposure to viruses and bacteria; even a minor cold could prove fatal.
Currently, there are two commonly used treatment options for children with ADA-SCID. They can be injected twice a week with the adenosine deaminase enzyme a lifelong process that is very expensive and often does not return the immune system to optimal levels. Some children can receive a bone marrow transplant from a matched donor, such as a sibling, but bone marrow matches are rare and can result in the recipients body rejecting the transplanted cells.
The researchers used a strategy that corrects the ADA-SCID mutation by genetically modifying each patients own blood-forming stem cells, which can create all blood cell types. In the trial, blood stem cells removed from each childs bone marrow were corrected in the lab through insertion of the gene responsible for making the adenosine deaminase enzyme. Each child then received a transplant of their own corrected blood stem cells.
The clinical trial ran from 2009 to 2012 and treated 10 children with ADA-SCID and no available matched bone marrow donor. Three children were treated at the National Institutes of Health and seven were treated at UCLA. No children in the trial experienced complications from the treatment. Nine out of ten were babies and they all now have good immune system function and no longer need to be isolated. They are able to live normal lives, play outside, go to school, receive immunizations and, most importantly, heal from common sicknesses such as the cold or an ear infection. The teenager, who was not cured, continues to receive enzyme therapy.
The fact that the nine babies were cured and the teenager was not indicates that the gene therapy for ADA-SCID works best in the youngest patients, before their bodies lose the ability to restore the immune system.
The next step is to seek approval from the Food and Drug Administration for the gene therapy in the hopes that all children with ADA-SCID will be able to benefit from the treatment. Kohn and colleagues have also adapted the stem cell gene therapy approach to treat sickle cell disease and X-linked chronic granulomatous disease, an immunodeficiency disorder commonly referred to as X-linked CGD. Clinical trials providing stem cell gene therapy treatments for both diseases are currently ongoing.
Kohn is a professor of pediatrics and microbiology, immunology and molecular genetics at the David Geffen School of Medicine at UCLA and member of the UCLAChildrens Discovery and Innovation Institute at Mattel Childrens Hospital. The first author of the study is Kit Shaw, director of gene therapy clinical trials at UCLA.
The research was published in the Journal of Clinical Investigation.
The research was funded by grants from the U.S. Food and Drug Administrations Orphan Products Clinical Trials Grants Program (RO1 FD003005), the National Heart, Lung and Blood Institute(PO1 HL73104 and Z01 HG000122), the California Institute for Regenerative Medicine (CL1-00505-1.2 and FA1-00613-1), the UCLA Clinical and Translational Science Institute (UL1RR033176 and UL1TR000124) and the UCLA Broad Stem Cell Research Center.

Neural Crest Stem Cells From Skin Without Genetic Modifications … – UB School of Medicine and Biomedical Sciences News
By daniellenierenberg
Stelios Andreadis, PhD, is leading a team of researchers who have discovered how to convert adult skin cells into stem cells without modifying their genetics.
UB researchers have found that adult skin cells can be converted into neural crest cells without any genetic modification.
The discovery, which was several years in the making, proves that these stem cells can yield other cells that are present in the spinal cord and brain.
The applications could be very significant, ranging from studying genetic diseases in a dish to generating possible regenerative cures from a patients own cells.
Its actually quite remarkable that it happens, says Stelios Andreadis, PhD, professor of biomedical engineering, who recently published a paper on the results, titled Reprogramming Postnatal Human Epidermal Keratinocytes Toward Functional Neural Crest Fates, in the journal Stem Cells.
The identity of the cells was further confirmed by lineage tracing experiments, where the reprogrammed cells were implanted in chicken embryos and acted just as neural crest cells do.
This image shows Keratinocyte-derived neural crest stem cells turning into neurons as shown by typical neuronal morphology.
Stem cells have been derived from adult cells before, but not without adding genes to alter the cells. The new process yields neural crest cells without addition of foreign genetic material. The reprogrammed neural crest cells can become smooth muscle cells, melanocytes, Schwann cells or neurons.
In medical applications this has tremendous potential because you can always get a skin biopsy, says Andreadis, who is also professor and chair of the Department of Chemical and Biological Engineering in the School of Engineering and Applied Sciences.
We can grow the cells to large numbers and reprogram them without genetic modification. So, autologous cells derived from the patient can be used to treat devastating neurogenic diseases that are currently hampered by the lack of easily accessible cell sources, he says.
The process can also be used to model disease. Skin cells from a person with a genetic disease of the nervous system can be reprogrammed into neural crest cells. These cells will have the disease-causing mutation in their chromosomes, but the genes that cause the mutation are not expressed in the skin.
The genes are likely to be expressed when cells differentiate into neural crest lineages, such as neurons or Schwann cells, thereby enabling researchers to study the disease in a dish. This is similar to induced pluripotent stem cells, but without genetic modification or reprogramming to the pluripotent state.
The discovery was a gradual process, taking almost five years, Andreadis says, as successive experiments kept leading to something new.
It was one step at a time. It was a very challenging task that involved a wide range of expertise and collaborators to bring it to fruition, he says.
Collaborators include:
Andreadis credits the persistence of his then-doctoral student, Vivek K. Bajpai, for sticking with it.
He is an excellent and persistent student, Andreadis says. Most students would have given up.
The research was supported by grants from the National Institutes of Health (NIH).
Andreadis also credits a seed grant from UBs Office of the Vice President for Research and Economic Developments IMPACT program that enabled part of the work.
The work recently received a $1.7 million NIH grant to delve into the mechanisms that occur as the cells reprogram, and to employ the cells for treating the Parkinsons-like symptoms in a mouse model of hypomyelinating disease.
This work has the potential to provide a novel source of abundant, easily accessible and autologous cells for treatment of devastating neurodegenerative diseases, Andreadis says. We are excited about this discovery and its potential impact and are grateful to NIH for the opportunity to pursue it further.

Hadassah is winning the battle with MS – Heritage Florida Jewish News
By daniellenierenberg
Malia
March is Multiple Sclerosis Month and Hadassah leads the world in the stunning success and implementation of the research at Hadassah Hospital in Jerusalem. Malia is just one of the many stories of triumph in Prof. Dimitrios Karussis program.
Malia was a top Dallas trial attorney-a senior partner in a law firm and the mother of three children, the youngest, age five. Her energy level was high and her life was full. And then, 18 years ago, she was diagnosed with multiple sclerosis (MS).
In the beginning, her symptoms were mild. For example, she was a little unsteady in her walking. She began taking a weekly injection of Avonex because, as her doctor told her, "You wouldn't want me to treat you for high blood pressure only after you had a heart attack."
Malia took Avonex for about 10 years. Still, her life became a journey of declining energy and mobility. Her biggest fear was that she would lose her vision and not be able to drive her children around. Fortunately, she didn't experience any problems with her vision, but her gait did get worse, as did the fatigue.
Ultimately, she could only walk a very short distance with a walker. Her balance became more unsteady. Her speech was harder to understand. And the fatigue got so bad that even taking a shower was so exhausting that she needed a nap afterward.
Malia tried four or five different medicines, but none seemed to help. As she explained, however, the promise of these medicines is only to slow the progression of the disease, not to improve upon one's symptoms.
At one point on this odyssey of decline, Malia fell and broke her leg and found herself in a wheelchair for six weeks. She began to research other treatment options, surfing the Internet extensively. It was how she came upon the innovative stem-cell work of Prof. Dimitrios Karussis, senior neurologist at Hadassah Hospital Ein Kerem and head of its Multiple Sclerosis Center. She learned that Prof. Karussis was conducting a unique MS clinical trial involving the injection of a patient's own bone marrow-derived stem cells directly into the spinal cord.
When she met Prof. Karussis for the first time, she was walking with a walker, but couldn't walk any real distance. It was December 2014. In the spring of 2015, Malia, who was accepted into one of Prof. Karussis' clinical trials, traveled back to Hadassah to have a bone marrow extraction, which would be the basis for her stem-cell transplant. As she explains, just a syringe of cells is extracted, but then these cells are enhanced in culture for six months. In the fall of 2016, Malia received her first infusion. The actual infusion, itself, Malia relates, took only five minutes!
"I got the infusion at 2 p.m.," Malia recalled, "and eight hours later, I did something I had not done in two to three years." She explained that before the infusion, whenever she got out of bed, to get back in, she would have to lift her right leg with her hands. This time, post infusion, after she got up to go to the bathroom, she was able to get back into bed by just lifting her right leg onto the bedwithout holding it! She called the kids; her husband, David, made a video of her new ability. When her doctors came in that next morning to see how she was doing, she showed them her new skill. "Everyone was sobbing," she recalled; "we were all so excited by how amazing it was."
Malia said: "The most important thing of all was that the level of my fatigue was so improved."
Taking herself back to the night she returned home from that first infusion, Malia recalled: "We arrived back home at midnight. The next morning at 8, I was up writing my blog. Then I unpacked, did laundry, and made a five-course dinner for my husband, after which he went to bed, exhausted from the jet lag. I, however, stayed up to crochet a new blanket until midnight."
That renewed energy has never disappeared since Malia started getting stem-cell infusions at Hadassah. She received two more in 2016 and the most recent in February 2017. The kind of improvements varied with each infusion-sometimes the improvement in her gait was most noticeable; other times, it was the clarity of her speech. With the 2017 infusion, it was her balance. A year or so ago, she could only balance herself on a "whole body vibration machine" for about a minute and a half. Then she worked this up to five minutes. After this fourth infusion, she could stay on the machine for 12 minutes and even let go of the bar with one hand.
In addition, before every infusion, a baseline measurement of her abilities is taken. The most recent baseline, Malia reported, was higher than ever before. By the same token, her overall physical improvements are the best they've been.
Malia's recovery is not without its setbacks. As the stem-cell treatment wears off, she does experience some backsliding in her improvements-perhaps in her speech or the way she walks. Nevertheless, after she has a treatment, the improvements return or surpass the previous ones.
"I had forgotten what it was like to feel like a regular person, like someone with a normal level of energy; I had forgotten what it was like to feel good," Malia said.
When she is out and about with her walker, she sees people looking at her with sympathy. But she doesn't feel sorry for herself, she notes, because she has gotten her life back. Malia feels blessed that she has come this far. "Until you've been there, you can't really understand just how important it is to feel like a regular person."
Malia had stopped practicing law when she was diagnosed with MS. But just recently she reactivated her law license. She took on a case, with a colleague. And in the beginning of April, she will be going to trial.
"When you feel like you can do things you used to do, life is as it should be," Malia said.
Malia no longer takes any medication for MS and being an MS patient is no longer a central focus of her life. But, she is now a stem-cell activist and fundraiser on behalf of Hadassah because "I feel I have been given a gift and I want to ensure that more people with MS can be helped."
While she doesn't know the other participants in the clinical trial, she did meet one man from London last time she was at the hospital for her infusion. As she relates, this man was "giddy with excitement, lifting his cane in the air with one hand." They began to talk and he explained that he just had his first stem-cell infusion and, overnight, he was able to lift his cane up in the air with his right hand when for 15 years he had been unable to even hold anything in that hand.
"What I would like Hadassah supporters around the world to understand," Malia related, "is that yes, I get the wonderful benefits of Prof. Karussis' stem-cell treatments (and, of course, she does not minimize his trailblazing hard work and miraculous success), "but I also was surprised to learn that I have this large Hadassah cheering squad that gives me hope and supports me-making me believe in possibilities for improvement. As Malia recalled, when she sits with a visitor from Hadassah and sees the look of awe on the face of this Hadassah supporter because of the leap in her improvement, it gives her renewed strength. "There are many things I want to do with the rest of my life," Malia said, "and raising money for Hadassah is at the top of the list."

Stem cell transplant reduces Culver woman’s MS symptoms – Bend Bulletin
By daniellenierenberg
Lacey Miller will probably never forget her sons first birthday, at least not for the usual reasons. She threw him a party at a park near their home in Culver. Throughout the whole thing, she couldnt walk and could barely see, merely moving was a challenge.
I just kind of sat there and everyone cleaned up and they got me back to the house, she said.
Miller has a form of multiple sclerosis, a disease that disrupts communication between the brain and the rest of the body. The symptoms numbness, difficulty concentrating, blurred vision and fatigue come in cycles and tend to worsen over time.
When she was diagnosed in 2012 at age 27, Millers symptoms werent so bad: little things like numbness in her legs and blurry vision. It wasnt until three years later, when she became pregnant with her son, that things went downhill fast. She had to be induced into labor early because she had so much trouble walking. After that, there was vertigo, vision loss and walking became more difficult. Her worsening symptoms culminated in an emergency room trip following her sons first birthday party.
I was going to be in a wheelchair in probably a year, she said.
Internet exploration brought her to a study at Northwestern University in Chicago that is further exploring the idea of, in a sense, resetting the immune systems of multiple sclerosis patients. Multiple sclerosis develops when a persons immune system attacks the protective covering of nerve fibers in the central nervous system, making it difficult for the brain to communicate with the rest of the body.
Miller applied to join the study in June 2016 and was approved in September. She started her testing and treatment in early January, embarking on what would be months of grueling treatments and travel.
Through it all, Miller thought about her now-18-month-old son, Emmerick.
Even on the days when it was like, This sucks. This is really hard, it was like, Im doing this for him so he can have a mom who can run down to the park with him and do things with him, she said.
Thats a win
A handful of prominent studies in recent years have raised hope that a procedure called hematopoietic stem cell transplantation can prevent further disability among patients with multiple sclerosis.
A study on 25 multiple sclerosis patients published last month gave further hope. Three years after undergoing stem cell transplants, disability symptoms in nearly 80 percent of the patients had not worsened, according to the study, published in the in the Journal of the American Medical Association Neurology. At five years, nearly 70 percent of the patients symptoms still had not worsened.
Dr. Linda Griffith, an author on the study and a medical officer at the National Institute of Allergy and Infectious Diseases, which sponsored the study, said being able to halt existing symptoms is a big advance.
To us, thats a win if they dont get worse, she said. We have no notion of being able to cure MS here and make it go away. Its not going to go away. Its a bad disease. But medical investigators are really thrilled and excited when they can find that the disease isnt getting worse.
Dr. Richard Burt, a professor of medicine and chief of immunotherapy at Northwesterns Feinberg School of Medicine, found similar results in a 2015 study he and his team published in the Journal of the American Medical Association. Five years after undergoing stem cell transplants, only 10 percent of multiple sclerosis patients had worsened symptoms.
The majority got better and stayed better, he said. Thats a paradigm change.
Creating hope
The stem cell transplant procedure involves extracting a patients bone marrow stem cells using a long needle and using chemotherapy and other toxic medications to clear out the rest of the cells. In multiple sclerosis patients, the patients own stem cells are then put back into the body.
It is now immature, just like if you were a child again and your immune system was learning all over again whats its supposed to be reacting against versus not, Griffith said.
While it sounds exciting, Griffith cautions the research is far from conclusive. She hearkens back to the hype around early studies that showed the procedure could be helpful for breast cancer patients. It ultimately wasnt.
What needs to happen next, she said, is a randomized study that compares groups of multiple sclerosis patients who either receive the transplant or the medications typically used to treat the condition, following them over time.
Not for everyone
Burt, the first doctor to perform these stem cell transplants for multiple sclerosis patients in the U.S., performed the procedure on Miller.
He cautions that only a specific subset of multiple sclerosis patients will benefit from the procedure. They must have a common form of the condition called relapse-remitting, meaning symptoms come in waves that recur over time. He doesnt perform the procedure on people who have progressed to a later stage, as it would be too late to help them, he said. Imaging on their brain and spine must show new lesions, indicating the disease is active.
Its frustrating because people learn about this on Facebook and want to get it, she said. Theyre upset when we decline them.
Burt is confident, however, that he knows who his procedure can help and who it cant help.
We developed this over many decades, he said.
When Miller, who is now 32, went in for testing with Burt, it was in the middle of an attack. She could barely walk into the office at Northwestern; her dad had to hold her arm for balance.
Although she was accepted into the study, getting her health insurance carrier on board proved to be a struggle and logistical issues delayed her ability to officially participate. Burt is still treating her under the study protocols, however, on whats referred to as a compassionate basis.
Millers first trip to Chicago was a short one for pre-study testing: imaging to check the progression of her multiple sclerosis, among other evaluations. She flew back to Chicago on Jan. 21 for what would be a two-week trip. First, they gave her chemotherapy to kill her stem cells and suppress her immune system. That meant she lost her hair.
Then they put a long needle into her neck to remove the remaining stem cells. She still has a tiny, round scar where the needle went in.
On Feb. 12, she flew back to Chicago again to have her stem cells put back into her body. She was discharged on March 1.
Sometimes, Burt said his patients notice right away the so-called MS fog, the fatigue and inability to think clearly, is lifted once they finish the procedure.
Miller said that was the case for her. She noticed other things right away, too. Walking around downtown Chicago was much easier after the surgery than before. She no longer had to use a cane or wall to guide her and she no longer had to stop and rest.
The other day, her fiance, Chris, asked her what the score of the basketball game was. She told him.
He was like, Can you see that? she said. I was like, Yeah! I didnt realize things are just so crisp and clear.
The near-constant numbness in her legs also isnt as bad as it used to be.
We were kind of joking the other day because my fiance touched my foot, she said. I was like Oh my god, I can feel that! I hadnt been able to feel my feet.
No more drugs
Burt theorizes that in addition to helping peoples quality of life, stem cell transplants could also help them financially, a point he hopes to flesh out in his current research.
A 2015 study in the journal Neurology found multiple sclerosis drugs cost patients roughly $60,000 per year. The price of the drugs increased annually between 1993 and 2013 at rates of five to seven times higher than the rate of prescription drug inflation, according to the study.
Miller, who works as a juvenile parole officer in Jefferson County, estimates she was spending about $500 a month on the drugs after her insurance paid its portion. She had to quit one medication a shot she gave herself three times per week because it gave her flu-like symptoms. Not having to take medications anymore was one of the main reasons Miller said she wanted to enroll in Burts study.
Im kind of one of those people that I dont even like taking Tylenol, she said. Id rather just not take anything.
Miller isnt currently on any multiple sclerosis medications. She said she hasnt felt this good in years. She returned to work part time this week.
Burt routinely travels to medical centers around the world explaining the procedure in hopes other neurologists will perform the stem cell transplants on multiple sclerosis patients. The older ones tend to be more set in their ways, but he believes the technique will catch on among younger doctors.
The procedure is currently being performed in England, Sweden and Brazil, Burt said. A hospital in India recently expressed interest, too.
At the end of the day, we want to help people throughout the world, Burt said, and in fact this is spreading throughout the world.

Strong Progress for Paralyzed Patients After Stem Cell Therapy, Company Says – KQED
By daniellenierenberg
A small stem cell trial in which patients with severe spinal injuriesappeared to make remarkable progress is still showing excellent results, according to the company conductingthe research.
One of the patients in the trial is 21-year-old Kris Boesen, from Bakersfield, California, whose story we reported on last year.A car crash had left theBakersfield, California native with three crushed vertebrae, almost no feeling below his neck, and a grimprognosis. Doctors believed he would live the rest of his life as a paraplegic.
Enter stem cell therapy. Most treatments for serious spinal injuries concentrate on physical therapy to expand the range of the patients remainingmotor skills and to limit further injury, not to reverse the actual damage. But last April, as part of an experimental phase 2 clinical trial called SCiStar, researchers injected Boesen with 10 million stem cells. By July, hehad recovered use of his hands to the point where he could use a wheelchair, a computer and a cellphone, and could take care of most of his daily living needs.In recent months his progress has continued, says his father.
Boesen is not the only patient to have improved in the trial, according toAsterias Biotherapeutics, which is conducting the research. Boesen is part of a cohort of six patients who were experiencing various levels of paralysis and were injected with the 10 million stem cell dose. In a Jan. 24update, the company saidfive of those patientshad improved either one or twolevels on a widely used scale to measuremotor function in spinal injury patients.
On Tuesday, Asterias issued a newupdate, announcingthat the sixth patient in the cohort has experienced a similar improvement.
While spontaneous recovery for spinal injury patients does occur,the likelihood of all six patients recovering to the degree they haveis less likely, researchers say.
This is as good as you could hope at this point, said Charles Liu, Boesens neurosurgeon and director of the USC Neurorestoration Center. So far all the evidence is pointing in the right direction.
To measure improvement in spinal injury patients, researchers use two yardsticks: the Upper Extremity Motor Scale, or UEMS, and the International Standards for Neurological Classification of Spinal Cord Injury, or ISNCSCI. On the UEMS scale,patients are scored from 0 to 5 on theirability to use five key muscles in the wrists, elbows and fingers. The ISNCSCI scale assesses where damage has occurred along the different levels of the cervical vertebrae, which generally determines the scope of impairment to the body and the level of care needed.
For instance, if a patient has sustained damage at the fourth cervical vertebra down, known as C-4, at the base of the neck, it generally means that person is paralyzed from the neck down, requiring round-the-clock care and a ventilator to breathe.A patient with a C-5 injury may not be able to move her arms or hands, requiring about 6 to 12 hours per day of assisted care; and at the C-6 level, better motor function mayallow a patient to take care of most of herdaily living needs on her own.
Which is all to say that even one level of recovery could substantially improve the daily life ofa spinal injury patient.
According to Asterias, all six patients in the 10million-cell cohort have improved their general UEMS scores, and jumped at least one motor level on the ISNCSCI scale on one or both sides of their body.
Two patients have improvedtwo motor levels on one side; and one patient,Boesen, has improved two motor levels on both sides.
Steve Cartt, president and CEO of Asterias, said anotherpatient, Jake Javier of Danville, California, has gonefrom partial paralysis to being able to use his hands well enough to considerpursuing a computer science career.
Throws Like a Regular Throw
In September, Boesens father, Rod Boesen, told us how excited he wasthat his son had regained some feeling in one of his feet. Last week, at11 months post-injection, the elder Boesensaid Kris has continued to improve.
Now he can move his toe and his knee together at the same time, Boesen said. Theyre about to give him a manual wheelchair now [instead of a motorized one]. He can grip with his hands enough to use a manual one.
Boesen said the movement in his sons arms and hands has greatlyimproved since September.Kris, a formerhigh school pitcher, had beenflinging a ball to his dog like people throw hand grenades, Boesen said. They kind of cradle them and thats how Kris would do it. But now he throws like a regular throw, tosses that ball down the hall, has that release point down, and just wings it.
Asterias is currently recruiting patients for a trial in which theyll receive 20 million stem cells, the optimal dose, according to company researchers. Two patients have already started the 20 million stem cell therapy, and six-month results from those patients will be released in the fall, Cartt said.
Patients who received 2 million stem cells in an earlier phase of the study have not shown much change in their condition, according to the Jan. 24 update.
Guarded Optimism
While Boesens father is impressed with the results, the optimism of researchers inside and outside the studyhas been guarded.The trial is still in its early stages, and the sample size is small, said Paul Knoepfler, a cell biology professor and stem cell researcher at UC Davis, who is not involved in the SCiStar study.
As a scientist, I still would want to wait for more data, Knoepfler said. Its certainly interesting, but its still early. Its a phase 2 trial.
To address the issue of small sample size, Asterias islooking at historical data to determinethe level of improvement for patients in similar circumstances who did not receive stem cell therapy. The company has said it found a meaningful difference in the recovery of its study patients compared to the norm.
Liu said one of the most importantresults is the lack of significant side effects or other negative outcomes resulting from the treatment to date.
Thats very significant to me, Liu said. Thats the first thing you look for, is anyone hurt from this therapy.
There was also a concern, he said, that some patients might regress over time, once the initial injection of stem cells wore off. Thathasyet to occur.
No one has lost anything theyve gained, Liu said. We were very happy to see that. This is all very promising.
The next step for the SCiStartrial will be to establish a control group, Cartt said.
