Newswise INDIANAPOLIS -- Like a line of falling dominos, a cascade of molecular events in the bone marrow produces high levels of inflammation that disrupt normal blood formation and lead to potentially deadly disorders including leukemia, an Indiana University-led research team has reported.
The discovery, published by the journal Cell Stem Cell, points the way to potential new strategies to treat the blood disorders and further illuminates the relationship between inflammation and cancer, said lead investigator Nadia Carlesso, M.D., Ph.D., associate professor of pediatrics at the Indiana University School of Medicine.
Bone marrow includes the cells that produce the body's red and white blood system cells in a process called hematopoiesis. The marrow also provides a support system and "home" for the blood-producing cells called the hematopoietic microenvironment. The new research demonstrates the importance of the hematopoietic microenvironment in the development of a group of potentially deadly diseases called myeloproliferative disorders.
"It has been known for years that there are links between inflammation and cancer, but these studies have been challenged by the lack of genetic models, especially for blood-based malignancies," said Dr. Carlesso, a member of the hematologic malignancy and stem cell biology program within the Wells Center of Pediatric Research at IU.
The researchers focused on what happens when there are abnormally low levels of a molecule called Notch, which plays an important role in the process of blood cell production. Using a genetically modified mouse, they found that the loss of Notch function in the microenvironment causes a chain of molecular events that result in excess production of inflammatory factors.
The high levels of inflammation in the bone marrow were associated with the development of a myeloproliferative disorder in the mice. Myeloproliferative diseases in humans can result in several illnesses caused by overproduction of myeloid cells, which are normally are used to fight infections. These diseases can put patients at risk for heart attack or stroke, and frequently progress into acute leukemia and bone marrow failure, which have fatal outcomes. Unfortunately, there are no effective therapies for the majority of myeloproliferative diseases.
When Dr. Carlessos team blocked the activity of one of the molecules in this biochemical cascade, the myeloproliferative disorder in the mice was reversed. In addition, elevated levels of the blocked molecule were found in samples from human patients with myeloproliferative disease. These findings suggest that developing drugs that target this inflammatory reaction at different key points could be a promising strategy to limit the development of myeloproliferative disease in humans.
The molecular cascade leading to inflammation was not occurring directly in the bone marrow cells that produce blood cells, but in cells of the bone marrow microenvironment, especially in endothelial cells that line the capillaries -- tiny blood vessels -- inside the bone marrow. This was a key discovery, Dr. Carlesso said.

Charlotte Crosby helps young boy in need of bone marrow transplant
By LizaAVILA
Geordie Shore star Charlotte Crosby has become the latest person to sign up to the Anthony Nolan bone marrow register
Geordie Shore star Charlotte Crosby has spat out her support for a baby in need of a life-saving operation.
Charlotte has signed up with the Anthony Nolan Trust after reading about the plight of nine-month-old Joey Ziadi, who is suffering from a rare blood disorder that affects one in nine million people.
The tot from Northampton needs a lifesaving transplant but has not yet found a matching donor so Charlotte has enlisted her 1.89m twitter followers to join the cause.
After hearing about Joeys plight, Charlotte tweeted a selfie with her Anthony Nolan spit kit - the simple piece of equipment which allows people to leave a DNA sample and go on the bone marrow donor register.
She said: I saw the gorgeous Joey Ziadi in the news and I couldnt believe it when I heard how ill he was and that only one in nine million people have his condition I felt like crying. I knew I had to do something, but I didnt know how to help.
When I found out how simple it was to sign up to the Anthony Nolan register, I didnt have to think about it. I just thought Its so easy, why doesnt everyone do this?
Anthony Nolan saves lives by matching people willing to donate their bone marrow or blood stem cells to patients in need of a transplant.
The charity also needs more young men to sign up, as they are most likely to be chosen to donate but make up just 14% of the register. Charlotte said: I was quite shocked that young lads are so underrepresented on the register though. Come on lads, just sign up online and spit into a tube! Im doing it, and I just hope one day I have the chance to save a life.
Joey was diagnosed with an extremely rare blood disorder Diamond Blackfan Anaemia in February. His family have been campaigning to recruit more potential donors to the Anthony Nolan donor register after being told that his best hope of a cure is a bone marrow transplant from a stranger.

South Reno Veterinary Hospital is Prolonging Pet Quality of Life with Stem Cell Therapy and the Ability to Bank Cells …
By LizaAVILA
Poway, CA (PRWEB) June 27, 2014
South Reno Veterinary Hospital and Mathew Schmitt, VMD have recently discovered the secret to prolonging a pets quality of life with the use of stem cell therapy, and the ability to bank stem cells for the future care of a pet. Dr. Schmitt and South Reno Veterinary Hospital offer stem cell therapy and stem cell banking through Vet-Stem, Inc. for small animal osteoarthritis and partial ligament tears.
As many as 65% of dogs between the ages of 7 and 11 years old will be inflicted with some degree of arthritis. For certain specific breeds the percentage is as high as 70, such as Labrador Retrievers. Barley, a Labrador mix, was treated using cells from a sample of his own fat, and some stem cells are also stored (or banked) with Vet-Stem just in case he needs future treatment with Dr. Schmitt. Those banked stem cells do not have to be used for the same use as they were originally used for either. For example, if a pet has stem cell therapy initially for osteoarthritis pain and inflammation, the banked stem cells can be used years later for an acute injury.
After rupturing the canine cruciate ligaments in both of his stifles, or hind knees, Barleys pain was managed by medication but then medication was finally not enough and he was facing the possibility of surgery. Dr. Schmitt reported shifting lameness in Barleys hind end, which was a sign of severe discomfort. Barleys owner did not want to put him through surgery on both knees. Instead, Barleys owner elected for stem cell therapy.
I fully believe stem cell therapy has significantly prolonged Barleys quality of life and I am so glad I found out about the therapy when he was injured at six years old. He just turned 13 and his legs are still doing well. It truly is a miracle of science and I tell all my friends about it, said Barleys mom.
Vet-Stem, along with countless research and academic institutions, is working to support additional uses for stem cells which may include treatment for liver disease, kidney disease, auto-immune disorders, and inflammatory bowel disease in animals. These uses for stem cells are in the early stages of development and may provide additional value to the ability to bank stem cells to ensure a pets quality of life into the future.
About Vet-Stem, Inc. Vet-Stem, Inc. was formed in 2002 to bring regenerative medicine to the veterinary profession. The privately held company is working to develop therapies in veterinary medicine that apply regenerative technologies while utilizing the natural healing properties inherent in all animals. As the first company in the United States to provide an adipose-derived stem cell service to veterinarians for their patients, Vet-Stem, Inc. pioneered the use of regenerative stem cells in veterinary medicine. The company holds exclusive licenses to over 50 patents including world-wide veterinary rights for use of adipose derived stem cells. In the last decade over 10,000 animals have been treated using Vet-Stem, Inc.s services, and Vet-Stem is actively investigating stem cell therapy for immune-mediated and inflammatory disease, as well as organ disease and failure.

CP Help Center Adds New Information About Cerebral Palsy Cord Blood Research
By LizaAVILA
Dallas, TX (PRWEB) June 24, 2014
The birth injury patient advocates at CerebralPalsyHelp.org are alerting parents of children with cerebral palsy of new research information on the site. Duke University was recently awarded a research grant to explore the use of umbilical cord cells to treat brain damage causing cerebral palsy and other conditions*.
The CP Help Center is a national advocacy center providing the latest on cerebral palsy treatment, clinical trials, resources and litigation news. Parents can learn more about their childs condition and how it may have been caused, get information on available assistance, and decide if they should seek legal advice.
Cerebral palsy affects muscle movement, coordination and posture. It is the leading cause of functional and developmental disability in children in the United States**, occurring in approximately 3.3 out of every 1,000 births, and affecting approximately 500,000 children**.
While CP affects muscle function, it is actually a neurological disorder caused by brain damage to the parts that control muscle function***. This usually occurs before, during or after birth***.
Cerebral palsy may be caused by factors occurring to the fetus during pregnancy, or by trauma or asphyxiation during labor***. There is no cure at this time, however, researchers are working towards better treatments.
Now, the CP Help Center has learned that Duke Medical Center has received a $15 million grant from the Marcus Foundation to begin two years of umbilical cord stem cell research, in what is eventually expected to become a five-year, $41 million study*.
Duke researchers will study whether cord blood can help repair dysfunctional or damaged parts of the brain and hope to develop cell-based therapies that could help millions affected by cerebral palsy, stroke or autism*. The study will include approximately 100 children with cerebral palsy, in trials that inject donated cord blood to treat their brain damage*.
Anyone whose child has been diagnosed with cerebral palsy should learn more about how their condition was caused, or speak with a lawyer about their legal options. The CP Help Center only recommends lawyers who specialize in cerebral palsy lawsuits.
For more information on the research, treatment, causes and litigation news related to cerebral palsy, or to speak with a lawyer, visit http://www.cerebralpalsyhelp.org today.

CP Help Center Adds New Information About Cerebral Palsy Cord Blood Research
Pushing cells towards a higher pluripotency state
By LizaAVILA
Stem cells have the unique ability to become any type of cell in the body. Given this, the possibility that they can be cultured and engineered in the laboratory makes them an attractive option for regenerative medicine. However, some conditions that are commonly used for culturing human stem cells have the potential to introduce contaminants, thus rendering the cells unusable for clinical use. These conditions cannot be avoided, however, as they help maintain the pluripotency of the stem cells.
In a study published in Scientific Reports, a group from the RIKEN Center for Life Science Technologies in Japan has gained new insight into the role of CCL2, a chemokine known to be involved in the immune response, in the enhancement of stem cell pluripotency. In the study, the researchers replaced basic fibroblast growth factor (bFGF), a critical component of human stem cell culture, with CCL2 and studied its effect. The work showed that CCL2 used as a replacement for bFGF activated the JAK/STAT pathway, which is known to be involved in the immune response and maintenance of mouse pluripotent stem cells. In addition, the cells cultured with CCL2 demonstrated a higher tendency of colony attachment, high efficiency of cellular differentiation, and hints of X chromosome reactivation in female cells, all markers of pluripotency.
To understand the global effects of CCL2, the researchers compared the transcriptome of stem cells cultured with CCL2 and those with bFGF. They found that stem cells cultured with CCL2 had higher expression of genes related to the hypoxic response, such as HIF2A (EPAS1). The study opens up avenues for further exploring the relationship between cellular stress, such as hypoxia, and the enhancement of pluripotency in cells. Yuki Hasegawa of CLST, who led the study, says, "Among the differentially expressed genes, we found out that the most significantly differentially expressed ones were those related to hypoxic responses, and hypoxia is known to be important in the progression of tumors and the maintenance of pluripotency. These results could potentially contribute to greater consistency of human induced pluripotent stem cells (iPSCs), which are important both for regenerative medicine and for research into diseases processes."
As a way to apply CCL2 towards the culturing of human iPSCs with more consistent quality, the researchers developed dishes coated with CCL2 and LIF protein beads. This allowed stem cells to be cultured in a feeder-free condition, preventing the risk that viruses or other contaminants could be transmitted to the stem cells. While the exact mechanisms of how CCL2 enhances pluripotency has yet to be elucidated, this work highlights the usefulness of CCL2 in stem cell culture.

Umbilical cord blood helps to save lives
By LizaAVILA
SOUTH BEND, Ind.--- In the 1970's, researchers discovered that a newborn's umbilical cord blood contained special stem cells that could help fight certain diseases.
More than 30 years later doctors are still experimenting and learning more about the use of cord blood.
Amanda Canale doesn't take time with her daughter and niece for granted.
She's just happy to feel good.
"I've been in the hospital, and I've been sick my whole life," said Amanda.
Amanda was born with a rare blood disorder that required daily shots.
"Basically, I have no white blood cells. I have no immune system at all," said Amanda
At 23 she developed Leukemia and was given two weeks to live.
She desperately needed a Bone Marrow Transplant, but family members weren't matches.
Her doctor suggested an Umbilical Cord Blood Transplant.

Lesson learned at Hutch helping dogs with lymphoma

BELLINGHAM A decade ago, the San Juan Island owners of Comet brought their beloved golden retriever to Drs. Edmund Sullivan and Theresa Westfall at Bellingham Veterinary to see if Comets diagnosis of lymphoma could be treated as something other than a death sentence.
The odds werent good.
At the time, lymphoma was considered incurable, with chemotherapy treatment only a temporary solution because the cancer nearly always re-emerged and resulted in death within a year.
Sullivan and Westfall, who are married, were determined to help. After talking to Dr. Rainer Storb, an expert on human lymphoma at Fred Hutchinson Cancer Research Center in Seattle, they decided to attempt a bone-marrow transplant on Comet. They spent six months visiting the center to learn how.
After removing and preserving bone-marrow stem cells in a painless procedure, the cells are stored for re-injection after radiation therapy. Through DNA analysis, the patients cells are checked for the presence of tumor cells. Sometimes, blood transfusions are needed to provide platelets and red blood cells during recovery.
Its a common procedure in humans but hadnt been tried with dogs.
It worked. Comet survived.
Since Comets recovery, more than 100 dogs have been cured with the treatment through Bellingham Veterinary, and three more veterinary hospitals around the country have been trained in the procedure. The 50 percent cure rate is considered extraordinary.
I didnt invent the procedure, Sullivan says. The knowledge was already out there and we just applied it to dogs.

Growing Stem Cells in Space: Medicine's Next Big Thing?
By LizaAVILA
FRESNO, Calif. (KFSN) --
It's something Jon Galvan experienced five years ago after he almost died from a hemorrhagic stroke while atSubmit work.
"I was typing away and I felt a pop in my head," Galvan told Ivanhoe.
He was able to recover, but Abba Zubair, MD, PhD, Medical Director of Transfusion Medicine and Stem Cell Therapy at Mayo Clinic, Florida says not everyone is as fortunate.
"If it happens, you either recover completely or die," Dr. Zubair told Ivanhoe. "That's what killed my mother."
SubmitDr. Zubair wants to send bone marrow derived stem cells to the international space station.
"Based on our experience with bone marrow transplant you need about 200 to 500 million cells," Dr. Zubair said.
But conventionally grown stem cells take a month. Experiments on earth have shown that stem cells will grow faster in less gravity.
"Five to ten times faster, but it could be more," Dr. Zubair said.
Specifically he hopes to expand the number of stem cells that will help regeneration of neurons and blood vessels in hemorrhagic stroke patients.

Promising T cell therapy to protect from infections after transplant
By LizaAVILA
When patients have to undergo a bone marrow transplant, the procedure weakens their immune system. Viruses that are usually kept in check in a healthy immune system may then cause potentially fatal infections. Scientists at Technische Universitt Mnchen (TUM), together with colleagues from Frankfurt, Wrzburg and Gttingen, have now developed a method which could offer patients conservative protection against such infections after a transplant. The method has already been used to treat several patients successfully.
The cells of the human immune system are created from special stem cells in the bone marrow. In diseases affecting the bone marrow, such as leukemia, the degenerate cells must be destroyed using radiation or chemotherapy. Subsequently, the hematopoietic system has to be replaced with stem cells from the blood of a healthy donor. Because of the resulting temporary weakening of the immune system, patients are more exposed to viruses that would normally be warded off.
The cytomegalovirus (CMV), which can cause serious damage to lungs or liver in persons with a weakened defense, poses a major clinical problem. In healthy human beings, a CMV infection will usually not produce any symptoms, since the virus is kept at bay by specific immune cells. In their work, the scientists were able to demonstrate that the transfer of just a few specific immune cells is sufficient to protect the recipient with the weakened immune system against infections. To do this, they used T cells that can recognize and kill specific pathogens.
Tested in an animal model
Dr. Christian Stemberger, first author of the study, and his colleagues, first isolated T cells from the blood of healthy donor mice. These immune cells were directed against molecular elements of a bacterial species which normally causes severe infections in animals. The T cells were then transferred to recipient mice that, due to a genetic modification, could no longer produce immune cells of their own -- similarly to patients suffering from leukemia.
Following the T cell transfer, the researchers infected the treated recipient mice with the bacteria. The results showed that the animals now have effective immune protection against the pathogens, preventing them from becoming ill. "The most astonishing result was that the offspring cells of just one transferred donor cell were enough to completely protect the animals," Christian Stemberger explains.
Successfully used in patients
Finally, the scientists used virus-specific T cells to treat two critically ill patients. Due to a congenital immunodeficiency and leukemia, respectively, stem cell transplants had to be performed on the two patients. Weakened by the procedure, both patients developed CMV infections.
Using a new method, the scientists therefore isolated T cells specifically programmed to target the CMV virus from the blood of the donor and transferred small numbers of these cells to the patients. After only a few weeks, the virus-specific cells proliferated. At the same time, the number of viruses in the blood dropped. "It is a great advantage that even just a few cells can provide protection. This means that the cells can be used for preventive treatment in low doses that are gentler on the organism," Dr. Michael Neuenhahn, last author of the study, explains.
The potential of the identified T cells will now be examined in a clinical study. In addition to an innovative method for cell purification, scientists also have at their disposal a new TUM facility for the sterile manufacture of cell products. In TUMCells, cells can be produced in highly-pure conditions, in so-called clean rooms. In the future, the scientists want to use recent results and TUMCells to develop innovative cell therapies.

Children's Research Institute Finds Key to Identifying, Enriching Mesenchymal Stem Cells

Newswise DALLAS June 20, 2014 The Childrens Medical Center Research Institute at UTSouthwestern (CRI) has identified a biomarker that enables researchers to accurately characterize the properties and function of mesenchymal stem cells (MSCs) in the body. MSCs are the focus of nearly 200 active clinical trials registered with the National Institutes of Health, targeting conditions such as bone fractures, cartilage injury, degenerative disc disease, and osteoarthritis.
The finding, published in the journal Cell Stem Cell on June 19, significantly advances the field of MSC biology, and if the same biomarker identified in CRIs studies with mice works in humans, the outlook for clinical trials that use MSCs will be improved by the ability to better identify and characterize the relevant cells.
There has been an increasing amount of clinical interest in MSCs, but advances have been slow because researchers to date have been unable to identify MSCs and study their normal physiological function in the body, said Dr. Sean Morrison, Director of the Childrens Research Institute, Professor of Pediatrics at UTSouthwestern Medical Center, and a Howard Hughes Medical Institute Investigator. We found that a protein known as leptin receptor can serve as a biomarker to accurately identify MSCs in adult bone marrow in vivo, and that those MSCs are the primary source of new bone formation and bone repair after injury.
In the course of their investigation, the CRI researchers found that leptin receptor-positive MSCs are also the main source of factors that promote the maintenance of blood-forming stem cells in the bone marrow.
Unfortunately, many clinical trials that are testing potential therapies using MSCs have been hampered by the use of poorly characterized and impure collections of cultured cells, said Dr. Morrison, senior author of the study and holder of the Mary McDermott Cook Chair in Pediatric Genetics at UTSouthwestern. If this finding is duplicated in our studies with human MSCs, then it will improve the characterization of MSCs that are used clinically and could increase the probability of success for well-designed clinical trials using MSCs.
Dr. Bo Zhou, a postdoctoral research fellow in Dr. Morrisons laboratory, was first author of the paper. Other CRI researchers involved in the study were Drs. Rui Yue and Malea Murphy, both postdoctoral research fellows. The research was supported by the National Heart, Lung, and Blood Institute, the Cancer Prevention and Research Institute of Texas, and donors to the Childrens Medical Center Foundation.

StemGenex Announces New Stem Cell Clinical Study for Multiple Sclerosis
By LizaAVILA
La Jolla, CA (PRWEB) June 17, 2014
StemGenex, the leading resource for adult adipose stem cell therapy in the US aimed at improving the lives of patients dealing with degenerative diseases, today announced their newest clinical study for Multiple Sclerosis. StemGenex believes that a commitment to the safety and efficacy of stem cell therapy are paramount when providing care to patients with life threatening diseases.
This clinical study is bringing to the field a new, unique type of stem cell therapy that has the possibility of being more effective than other stem cell treatments currently available. Patients who receive stem cell treatment through StemGenex for Multiple Sclerosis will receive StemGenex multiple administration protocol. This consists of four targeted administration methods of the stem cells to deliver the necessary amount of stem cells past the blood brain barrier.
Principal Investigator Dr. Jeremiah McDole, Ph.D. stated, "Currently available drugs for multiple sclerosis do not halt disease progression or aid in the repair of established damage. We strive to provide regenerative medicine applications that address this critical, underlying issue. While patients experience positive clinical outcomes as a result of stem cell treatment, large, rigorously performed studies are desired in order to guide our best efforts for future development. The study we are conducting is designed to provide us with this essential data."
This study is registered through The National Institutes of Health which can be found at http://www.clinicaltrials.gov and is being conducted under IRB approval. According to StemGenex Director of Patient Advocacy, Joe Perricone, It is important patients have access to top-tier stem cell treatment. By providing access to registered clinical studies through The National Institutes of Health, we are providing patients with the ability to choose a stem cell treatment center with the highest standard of care.
Rita Alexander, founder and president of StemGenex, stated, This is the first of many stem cell clinical studies to come and a positive step for the more than 2 million people around the world suffering with Multiple Sclerosis. The average lifetime cost of current standard of care treatment per MS patient is $1.2 million. The human cost of the disease including pain and suffering endured by MS patients, the profound impact on families and the loss of their ability to contribute to society is without question immeasurable. Dr. McDoles research background in neuroimmunology is certainly an asset in our effort to change the course of neurological diseases.
Stem cell treatment studies are currently being offered by StemGenex to patients diagnosed with Multiple Sclerosis and other degenerative neurological diseases. StemGenex takes a unique approach of compassion and empowerment while providing access to the latest stem cell therapies for degenerative neurological diseases including Parkinsons and Alzheimers disease, stroke recovery and others.

BOSTON (CBS) Behaylu Barry is on the mend at home in Stratham, New Hampshire, after 34 days at Boston Childrens Hospital.
Behaylu, 13, received a bone marrow transplant in an effort to rebuild his immune system, compromised by a rare blood disorder.
I didnt feel like I had anything at all until I started doing something, said Behaylu of his aplastic anemia, diagnosed in February.
The star athlete scored seven goals in a January soccer game but a week later, felt exhausted and out of breath. Nose bleeds and infected cuts led his parents to believe something was seriously wrong. When doctors told Midori and Aidan Barry that Behaylu would need a bone marrow transplant, it was terrifying to hear.
The reality is we havent had time to think about it. Youre a parent. You go into campaign mode, said Aidan. That campaign lead the Barrys back to a village in Ethiopia where they first met Behaylu in 2007. Then 6-years-old, his biological parents couldnt afford to care for Behaylu so they put him up for adoption. Though the Barrys had three grown children of their own, they brought Behaylu home and eventually began assisting his other siblings still in Africa.
We thought we were helping them. We never thought theyd help us, said Aidan of the familys quick response to the Barrys request for cheek swabs, in an attempt to find a bone marrow donor for Behaylu. Two of his five siblings were perfect matches. Rediat, 16, and Eden, 10, quickly came to the United States.
The trio had two weeks to reconnect, even attending a New England Revolution game when the team was gracious enough to donate box seats. Behaylus compromised immune system makes it dangerous for him to be exposed to crowds.
During the visit, doctors decided Rediat should be the bone marrow donor. The two brothers underwent the painful procedure in May. Behaylu also received chemotherapy. Now his body is building a new immune system with the help of stem cells from Rediat.

Newswise San Antonio, June 10, 2014 Texas Biomedical Research Institute has recruited two new research scientists to its Southwest National Primate Research Center (SNPRC) who will focus on regenerative medicine, working with animal models to develop human stem cell therapies for medical conditions such as Parkinsons disease, degenerative diseases of the eye and muscular dystrophy.
Tiziano Barberi, PhD and Marcel M. Daadi, PhD join Texas Biomed as Associate Scientists in the SNPRC. Barberi comes from the Australian Regenerative Medicine Institute at Monash University in Melbourne, Australia and Daadi arrives from Palo Alto, CA where he was part of the Consulting Faculty of Stanford Universitys Department of Neurosurgery. He is also President and Chief Scientific Officer of NeoNeuron LLC.
Dr. Barberi and Dr. Daadi are significant additions to our regenerative medicine research program, Texas Biomed President and CEO Kenneth P. Trevett said. Both have focused on stem cell research, have published significant research results in peer review journals and received recognition for their leading roles within research teams and at institutions. Regenerative medicine is a major focus for Texas Biomed, where we have new facilities and financial resources dedicated for that purpose, he said. We also look to expand our work with other institutions and groups in San Antonio to promote progress in this field. Dr. Barberi and Dr. Daadi both have strong backgrounds in developing collaborative efforts, and we look forward to the contributions they will make in this important research arena.
Barberi, a native of Italy, had been one of 15 Chief Investigators of the Stem Cells Australia Consortium for stem cell research and Group Leader for the Australian Regenerative Medicine Institute. With a laboratory research focus on the directed differentiation of human pluripotent stem cells (hESC and iPSC) into specific developmental fates, his research aims are to provide tools for human development studies, in vitro disease modeling and a cell therapeutics approach to disease. He described in a seminal work a method to obtain all the clinically relevant neuronal subtypes from mESC, and was the first to have directed differentiation of hESC into mesenchymal precursors and into the progenitor cells forming the skeletal muscle system.
Prior to his work in Australia, Barberi was head of the Laboratory of Stem Cells and Development at the Beckman Research Institute of City of Hope in Duarte, CA. During the time spent at City of Hope, Barberi was awarded the prestigious New Faculty Award from the California Institute for Regenerative Medicine (CIRM). He is an invited reviewer for a number of stem cell-related research journals and is a grant reviewer/assessor for research programs in Canada, Australia, New Zealand and the European Union.
Daadi has unique academia and industry experiences bridging basic and translational research. He comes to Texas Biomed from the San Francisco bay area where he founded a biotechnology company, NeoNeuron, focused on developing therapies for treating neurological disorders. He served as Director of Stem Cell Research, CIRM Disease Team Stroke Neural Transplant Program at Stanford University School of Medicine and Director of the Parkinson's Disease Program at the Sanford Burnham Medical Research Institute, Layton Biosciences Inc and NeuroSpheres LLC.
At Stanford University, Daadi developed a novel technology to purify homogenous populations of neural stem cells from human pluripotent stem cells and coax them to specific types of neurons that can be used for brain repair. His research is paving the way for clinical trials to treat patients with devastating neurological disorders, such as Parkinsons disease, stroke and traumatic brain injury. He seeks to expand on the capabilities of the SNPRC and to build new collaborative programs and projects in stem cell research with colleagues at the University of Texas Health Science Center at San Antonio and the University of Texas at San Antonio.
Daadi serves as editor and reviewer for many peer review journals. He is a permanent member on the National Institutes of Health Grant Review Committee, The Maryland Stem Cell Research Fund and serves on many other national and international Grant Review Committees.

Texas Biomed Regenerative Medicine Program Expands With Two New Research Scientists
Stem cells edited to produce an HIV-resistant immune system
By LizaAVILA
A team of haematologists has engineered a particular white blood cell to be HIV resistant after hacking the genome of induced pluripotent stem cells (iPSCs).
The technique has been published in the Proceedings of the National Academy of Sciences and was devised by Yuet Wai Kan of the University of California, former President of the American Society of Haematology, and his peers.
The white blood cell the team had ideally wanted to engineer was CD+4 T, a cell that is responsible for sending signals to other cells in the immune system, and one that is heavily targeted by the HIV virus. When testing for the progress of HIV in a patient, doctors will take a CD4 cell count in a cubic millimetre of blood, with between 500 and 1,500 cells/mm3 being within the normal range. If it drops below around 250, it means HIV has taken hold -- the virus ravages these cells and uses them as an entry point.
HIV gains entry by attaching itself to a receptor protein on the CD+4 Tcell surface known as CCR5.If this protein could be altered, it could potentially stop HIV entering the immune system, however. A very small number of the population have this alteration naturally and are partially resistant to HIV as a result -- they have two copies of a mutation that prevents HIV from hooking on to CCR5 and thus the T cell.
In the past, researchers attempted to replicate the resistance by simply transplanting stem cells from those with the mutation to an individual suffering from HIV. The rarity of this working has been demonstrated by the fact that just one individual,Timothy Ray Brown(AKA the Berlin patient), has been publicly linked to the treatment and known to be HIV free today. The Californian team hoped to go right to the core of the problem instead, and artificially replicate the protective CCR5mutation.
Kan has been working for years on a precise process for cutting and sewing back together genetic information. His focus throughout much of his career has been sickle cell anaemia, and in recent years this has translated to researching mutations and how these can be removed at the iPSC stage, as they are differentiated into hematopoietic cells. He writes on his university web page: "The future goal to treatment is to take skin cells from patients, differentiate them into iPS cells, correct the mutations by homologous recombination, and differentiate into the hematopoietic cells and re-infuse them into the patients. Since the cells originate from the patients, there would not be immuno-rejection." No biggie.
This concept has now effectively been translated to the study of HIV and the CD+4 T cell.
Kan and his team used a system known as CRISPR-Cas9 to edit the genes of the iPSCs. It uses Cas9, a protein derived from bacteria, to introduce a double strand break somewhere at the genome, where part of the virus is then incorporated into the genome to act as a warning signal to other cells. An MIT team has already used the technique to correct a human disease-related mutation in mice.
When Kan and his team used the technique they ended up creating HIV resistant white blood cells, but they were not CD+4 T-cells. They are now speculating that rather than aiming to generate this particular white blood cell with inbuilt resistance, future research instead look at creating HIV resistant stem cells that will become all types of white blood cells in the body.
Of course, with this kind of therapy the risk is different and unexpected mutations could occur. In an ideal world, doctors will not want to be giving constant cell transplants, but generating an entirely new type of HIV resistant cells throughout the body carries its own risks and will need stringent evaluation if it comes at all close to being proven.

Dozens of men stepped forward to offer their cheek cells for testing in the hope of assisting patients in need of stem cell or bone marrow transplants.
On Saturday, the Village Brewery offered beer tastings and tours to those who took part in the swab-a-thon.
The event was created by Steve Carpenter, the operator of a local micro-brewery, whose brother Al was diagnosed with a rare form of leukemia in November. Al, married and the father of two, was in desperate need of stem cell treatment and Canadian Blood Services was unable to locate a suitable match through its stem cell and bone marrow donor program.
Steve and his friends organized a swab-a-thon in the hopes of locating a suitable donor, and Jim Button, a childhood friend of Als and the owner of Village Brewery, offered the use of his brewery.
Miraculously, in the days before the swab-a-thon was to be held, a suitable stem cell match was located for Al and he underwent treatment in an Ottawa hospital. Doctors say Al is responding well to the treatment.
Despite the fact a donor had been located for his brother, Steve made the decision to continue with his plans for Saturdays event.
We are here to tell people it is a very easy program, said Steve. We really appreciate anybody coming out to sign up on registry, be it for my brother or any other people in need.
Mike Carron was the first volunteer to step up to register and offer up a saliva sample. He says he wanted to help the cause after stem cell treatment extended the life of a close family member.
I thought it would be good to pay it forward, explains Carron. I had an uncle who needed stem cell treatment three years ago and it gave him an extra three years.

Stem Cells Treat Multiple Sclerosis in Mice
By LizaAVILA
Human embryonic stem cells the bodys powerful master cells might be useful for treating multiple sclerosis, researchers reported Thursday.
A team has used cells taken from frozen human embryos and transformed them into a type of cell that scientists have hoped might help treat patients with MS, a debilitating nerve disease.
Mice with an induced version of MS that paralyzed them were able to walk freely after the treatment, the teams at Advanced Cell Technology and ImStem Biotechnology in Farmington, Connecticut, reported.
The cells appeared to travel to the damaged tissues in the mice, toning down the mistaken immune system response that strips the fatty protective layer off of nerve calls. Its that damage that causes symptoms ranging from tremors and loss of balance to blurry vision and paralysis.
These embryonic stem cells were carefully nurtured to make them form a type of immature cell called a mesenchymal stem cell. These cells worked better to treat the mice than naturally developed mesenchymal stem cells taken directly from bone marrow, the team wrote in the journal Stem Cell Reports, published by the International Society for Stem Cell Research.
The top mouse is paralyzed, while the mouse on the bottom was treated with human embryonic stem cells and is able to run around.
The company released a video to show the benefits. Untreated mice were suffering. They are paralyzed. They on their backs. They are dragging their limbs. They are in really sad shape, ACTs chief scientific officer, Dr. Bob Lanza, told NBC News.
Treated animals, they are walking and jumping around just like normal mice.
Lanza says human trials are many months away, but he thinks it will not be necessary to use controversial cloning technology to make perfectly matched human embryonic stem cells to treat patients.
We can use an off-the-shelf source and itll work for everyone, he said. So you can use them and not worry about rejection.

Stem Cells Successfully Transplanted And Grown In Pigs

One of the biggest challenges for medical researchers studying the effectiveness of stem cell therapies is that transplants or grafts of cells are often rejected by the hosts. This rejection can render experiments useless, making research into potentially life-saving treatments a long and difficult process. Now, researchers at the University of Missouri have shown that a new line of genetically modified pigs will host transplanted cells without the risk of rejection.
The rejection of transplants and grafts by host bodies is a huge hurdle for medical researchers, said R. Michael Roberts, Curators Professor of Animal Science and Biochemistry and a researcher in the Bond Life Sciences Center. By establishing that these pigs will support transplants without the fear of rejection, we can move stem cell therapy research forward at a quicker pace.
In a published study, the team of researchers implanted human pluripotent stem cells in a special line of pigs developed by Randall Prather, an MU Curators Professor of reproductive physiology. Prather specifically created the pigs with immune systems that allow the pigs to accept all transplants or grafts without rejection. Once the scientists implanted the cells, the pigs did not reject the stem cells and the cells thrived. Prather says achieving this success with pigs is notable because pigs are much closer to humans than many other test animals.
Many medical researchers prefer conducting studies with pigs because they are more anatomically similar to humans than other animals, such as mice and rats, Prather said. Physically, pigs are much closer to the size and scale of humans than other animals, and they respond to health threats similarly. This means that research in pigs is more likely to have results similar to those in humans for many different tests and treatments.
Now that we know that human stem cells can thrive in these pigs, a door has been opened for new and exciting research by scientists around the world, Roberts said. Hopefully this means that we are one step closer to therapies and treatments for a number of debilitating human diseases.
Roberts and Prather published their study, Engraftment of human iPS cells and allogeneic porcine cells into pigs with inactivated RAG2 and accompanying severe combined immunodeficiency in the Proceedings of the National Academy of Sciences.

The Adult Stem Cell Technology Center, LLC Announces New Technology for Preventing Catastrophic Adult Stem Cell …
By LizaAVILA
Boston, MA (PRWEB) June 03, 2014
Today, Dr. James L. Sherley, the Director of Bostons Adult Stem Cell Technology Center, LLC (ASCTC) described a new technology for identification of new drug candidates that are toxic to adult stem cell cells in the human body. The new AlphaSTEM technology is the first of its kind to address a long-standing unmet need in the pharmaceutical industry.
Dr. Sherley presented the AlphaSTEM technology at the 7th Annual Massachusetts Life Sciences Innovation Day (MALSI Day 2014; http://www.mattcenter.org/malsi-day-2014/home.html) at the Harvard Club of Boston. ASCTC is one of a select number of start-up companies invited to present posters on their newest innovative biotechnologies at the all day event, which features the best and brightest life sciences innovations of the year.
Just as adult stem cells are crucial for life and normal organ function, their safety is crucial for successful treatment with new drugs. Even if a new drug has high activity against a disease or disorder; it will not be an effective treatment, if it is also too toxic to adult stem cells.
Adult stem cells are found in all renewing tissues and organs of the human body, like hair, skin, liver, and even the brain. They are responsible for replacing old mature tissue cells with new young cells. They are also essential cells for repairing injured tissues and wounds.
Some drugs are known to harm adult stem cells. Examples of these are many cancer drugs. Cancer drugs are often administered at the highest doses at which patients can tolerate the adverse effects of the drugs on adult stem cells. ASCTCs AlphaSTEM technology could accelerate discovery of better cancer drugs with less adult stem cell toxicity.
The major application proposed for the new AlphaSTEM technology is use by pharmaceutical companies to identify adult stem cell-toxic drugs before initiating clinical trials with them or entering the marketplace. Drug failure in clinical trials due to safety concerns is a major unrecovered cost of drug development. Chronic adult stem cell toxicity that now may go undetected until after marketing can result in tragic deaths for patients and catastrophic injury liabilities for the responsible drug companies. The Merck drug Vioxx is an example of such an unfortunate mishap.
The problem faced by the Food and Drug Administration (FDA) and the pharmaceutical industry is how to monitor drug effects on adult stem cells, when the cells are difficult to identify, isolate, produce, and count. The solution presented by ASCTC was a computer simulation approach based on the universal tissue cell production properties of adult stem cells.
ASCTC partnered with AlphaSTAR Corporation, a leading global provider of simulation technologies, to develop the AlphaSTEM software program that can simulate the culture multiplication of adult tissue stem cells found in any human tissue. AlphaSTEM technology not only has the power to detect drug toxicity against adult stem cells, but also against other specialized types of tissue cells specifically.
Director Sherley predicted that the introduction of AlphaSTEM technology into the pharmaceutical industry would have many immediate benefits. With relatively inexpensive detection of drugs destined to fail in expensive clinical trials, the new technology could save billions of currently wasted dollars, reducing overall drug development costs in the U.S. by as much as 20%. These savings could accelerate the rate of arrival of new effective drugs to patients by a comparable reduction in time. AlphaSTEM technology may also reduce the occurrence of drugs thought safe, but which actual have a lurking toxicity that emerges as lethal to some patients with wider and longer use.
