Cedars-Sinai investigators have identified a stem cell-regulating gene that affects tumor growth in patients with brain cancer and can strongly influence survival rates of patients. The findings, published in the online edition of Scientific Reports, could move physicians closer to their goal of better predicting the prognosis of patients with brain tumors and developing more personalized treatments for them.

To enhance understanding of how glioma cancer stem cells (GCSCs) reproduce and how they affect patient survival, investigators spent three years analyzing the genetic makeup of more than 4,000 brain tumors. During their investigation, they identified the gene, called ZEB1, that regulates tumor growth. The investigators' analysis suggests that brain cancer patients who don't have the gene tend to have lower survival rates.

"Patients without the gene in their tumors have more aggressive cancers that act like stem cells by developing into an uncontrollable number of cell types," said John Yu, MD, vice chair of neurosurgical oncology in the Department of Neurosurgery and senior author of the study. "This new information could help us to measure the mutation in these patients so that we are able to provide a more accurate prognosis and treatment plan."

Brain cancer occurs when cancer cells -- also called malignant cells -- arise in the brain tissue. This year, more than 23,000 people will develop primary cancerous tumors of the brain. Approximately 16,000 of those patients will die, according to the National Cancer Institute and the American Cancer Society.

Yu and fellow researchers noted that while some brain cancer patients are born without the gene, others have it but over time, the gene has become less powerful -- which could have had a role in causing the disease.

"We found an 8 -month shorter survival rate in lower grade glioma patients with the ZEB1 gene mutation compared to those individuals who have the gene," said Yu, who also serves as director of Surgical Neuro-Oncology at Cedars-Sinai. "We are learning that some chemotherapies are not effective in the population of individuals who have the gene deletion so we have to treat them with different medications."

The study was funded by FasterCures, a center of the Milken Institute, and the National Institutes of Health, grant #NS048959.

Cedars-Sinai investigators who collaborated on the study included Keith L. Black, MD; Lincoln A. Edwards, PhD; Dror Berel; Mecca Madany; Nam-Ho Kim, PhD; Minzhi Liu; Mitch Hymowitz; Benjamin Uy; Rachel Jung; Minlin Xu; Altan Rentsendorj, PhD; and Xuemo Fan, MD, PhD.

Also contributing were researchers from Neuro-Oncology Branch, National Cancer Institute.

The Yu Laboratory focuses on immune and stem cell therapy for brain tumors, cancer stem cells and their microenvironment in brain tumors. Led by Yu, investigators have developed vaccine-based immunotherapy for brain tumors that led to multi-institutional, randomized placebo-controlled clinical trials, as well as bone marrow-derived neural stem cells for the treatment of cancer and neurodegenerative diseases.

Yu said future studies will explore specific drug regimens and their efficacy in patients with gene mutations of the stem cell gene.

TiGenix has receivedpositive feedback from the FDA on an improved global phase III trial protocol for its lead candidateCx601 for Crohns disease. This is expected tospeed up US approval.

TiGenix is a Belgian companydevelopingstem cell therapies. The biotech is currently pushing its lead candidateCx601to the market for the treatment ofcomplex perianal fistulas in Crohns disease patients. Cx601 recently revealedpositive resultsin a European phase III study.

Following these results, the company submitted a number of technical adjustments for itspivotal phase III study for Biologics License Application (BLA) in the US, which were now approved by the FDA and are expected to acceleratethe process to US marketing authorization.

TiGenix is wellknown for its productChondroCellect, which was the first cell therapyto reach approval on the European market for the repair of knee cartilage.After the companyrecently withdrew its market authorization for this product, due to a lack of reimbursement, the biotech is focusing on its new leadCx601.

Thisproduct, currently awaiting EMA approval, consists ofallogeneic expanded adipose-derived stem cells (eASC), which are indicated for the treatment ofperianal fistulas in Crohns disease. The therapeuticeffects of eASCs are based on immunomodulatory abilities of these stem cells, which canrestore immune balance by suppressing a variety of immune cell subsets and inducing the generation of regulatory T cells.

Areas of the colon commonly affected duringCrohns disease

The current approval from the FDA will allow TiGenix to file the BLAbased on the efficacy and safety follow-up of patients at week 24, instead of week 52.The FDA has also agreed to accept fewer patients than originally planned in the study and endorsed a broader target population that will ultimately facilitate the recruitment process.

We believe that this revised protocol will allow us to file for approval one year earlier than we had originally plannedconcludedMaria Pascual, VP Regulatory Affairs & Corporate Quality of TiGenix

The current amendments will allow TiGenix to push its therapyto the US market even faster, which might pivotal for the company in light of its financial situation. After its shares had reached a low of22 cents back in 2013, the share price is currently still under 1. Withits low 34M IPO on Nasdaq in the end of last year, its market cap is stillonly at 191M. A low sum for a late stage clinical company.

As the EMAapproval forCx601 is expected soon, which will then be commercialized by Takeda, the company may actually be underestimated. The biotech recently started a new Phase Ib/IIa trial to testCx611 as a treatment for sepsis in patients with pneumonia.

Asecond platform consisting of transplanted allogeneic cardiac stem cells (AlloCSC)is currently in Phase II for acute myocardial infarction. It seems like TiGenix is definitely clinging toits position as one of the pioneers in stem cell-based therapies.

People with a certain gene have an adverse reaction to the antiretroviral efavirenz

Liz HighleymanCorrespondent An HIV-positive bone marrow transplant recipient at the Mayo Clinic experienced prolonged viral remission lasting nearly 10 months longer than the so-called Boston patients after interrupting antiretroviral therapy (ART), according to a report at the Conference on Retroviruses and Opportunistic Infections (CROI 2017) last month in Seattle.

Although his viral load eventually rebounded, his HIV reservoirs appeared to be reduced.

The only person known to be cured of HIV Timothy Ray Brown, known as the Berlin Patient stopped ART when he received a bone marrow transplant to treat leukaemia and has not had detectable virus for 10 years. Brown received a transplant from a donor with a double CCR5-delta-32 mutation, meaning they lack the CCR5 co-receptors most types of HIV use to enter T-cells.

It is unclear whether his sustained remission is attributable to the donors CCR5 mutation, the strong chemotherapy conditioning regimen used to kill off cancerous blood cells, a graft-versus-host reaction or multiple factors.

Bone marrow transplantation is apparently not sufficient to eradicate HIV.

A few years ago, Timothy Henrich reported on two HIV-positive bone marrow transplant patients in Boston who got stem cells from wild-type donors without the CCR5-delta-32 mutation, received a milder conditioning regimen and experienced acute graft-versus-host disease (GVHD). Both men maintained undetectable viral load longer than expected after interrupting ART, but eventually they experienced viral rebound at three and eight months after stopping HIV treatment.

The latest case, presented by Nathan Cummins of the Mayo Clinic in Rochester, Minnesota, and colleagues, involved a 55-year-old man who was diagnosed with HIV in 1990 and started combination ART in 1999 with a CD4 T-cell count of 300 cells/mm3. He stopped treatment between 2004 and 2009 for unexplained reasons, then restarted ART consisting of ritonavir-boosted atazanavir (Prezista) plus tenofovir disoproxil fumarate (DF) and emtricitabine (the drugs in Truvada).

In April 2013 the man was diagnosed with B-cell acute lymphoblastic leukaemia.

In anticipation of chemotherapy, his ART regimen was switched to raltegravir (Isentress), etravirine (Intelence), and tenofovir DF/emtricitabine. In October 2013 he underwent reduced intensity conditioning followed by an allogeneic stem cell transplant from a CCR5 wild-type donor.

At the time of transplantation the man had an HIV viral load of 25 copies/ml and a CD4 count of 288 cells/mm3, and he stayed on ART without interruption. After the transplant he developed opportunistic infections (E. coli septicaemia and pneumocystis pneumonia) and experienced GVHD at four months post-transplant.

The man continued on ART for more than two years after transplantation, mostly with detectable plasma viral load levels. HIV RNA was also undetectable in gut biopsy samples. HIV DNA in his peripheral blood cells became undetectable by day 56, and repeated leukapheresis procedures showed significant reductions in HIV RNA and DNA reservoir size.

In addition, that mans HIV antibody levels decreased, as indicated by weaker Western blot bands. However, single genome sequencing and phylogenetic analysis identified identical HIV clones at day 142, possibly due to homoeostatic proliferation, or replication of latently infected cells, while he had GVHD.

After having such low HIV levels for a prolonged period, the man underwent an analytic treatment interruption, or carefully monitored discontinuation of ART. His plasma HIV RNA levels were tested every two weeks for the first 12 weeks of ART interruption, then every four weeks.

At day 288 9,6 months after stopping ART he was found to have low-level viral rebound to 60 copies/ml. This rose to 1640 copies/ml by day 293, requiring that he restart HIV treatment.

The man had no evidence of drug resistance and his viral load was re-suppressed within a month.

Allogeneic peripheral blood stem cell transplantation in the setting of HIV is associated with significant reductions in HIV reservoir size by multiple measures, including prolonged combination ART-free remission, the researchers concluded.

They added that stem cell transplantation in the setting of suppressed viral replication may be associated with loss of HIV-specific immunity, and hypothesised that immune activation in the setting of GVHD without anti-HIV specific immunity may cause homoeostatic proliferation of latently infected cells, decreasing the chance of HIV eradication. http://www.aidsmap.com.

Dr. Kenneth Pettine, a board certified retired Orthopedic Surgeon and one of the Top 50 Spine Surgeons and Specialist to Know according to Becker's Spine Review, is offering to educate the public about mesenchymal stem cell therapy in Northern Colorado. Mesenchymal stem cells are being studied by Dr. Pettine for their ability to treat orthopedic conditions such as osteoarthritis and other joint and disc related chronic neck and back pain.

(PRWEB) March 07, 2017

Dr. Kenneth Pettine, a Northern Colorado board-certified retired orthopedic surgeon, is currently researching the use of the mesenchymal stem cell and their potential in treating orthopedic conditions such as osteoarthritis or other joint and disc related issues. He's now releasing more information about what these incredible stem cells are and the exciting therapeutic opportunities of mesenchymal stem cell therapy for the interested public in Northern Colorado.

Stem cells are rare, unique cells in our body that can duplicate themselves over and over again and can continue to regenerate throughout our lives. Each particular stem cell can only become either one type or a very limited number of cell types. As we get older, we have fewer stem cells in our body, which is why we have a decreased ability to heal and avoid diseases like cancer. Introducing new stem cells to the body could help counteract the effects of degenerated joints and chronic neck and back pain.

Mesenchymal stem cell are one type of stem cell, and the one that Dr. Pettine is using to focus his clinical research on stem cell therapy. This particular type of stem cell modulates your immune system, is extremely anti-inflammatory and has many positive effects in helping your body treat autoimmune conditions. The mesenchymal stem cell is the main cell helping your body heal from orthopedic and spine injuries and helping treat degenerative conditions such as arthritis.

Almost all of this research involves mesenchymal stem cells obtained from bone marrow. Most all these studies involved obtaining the mesenchymal stem cell from a donor's bone marrow and then expanding these cells in a laboratory. The number of mesenchymal stem cells in a petri dish can be increased to result in several hundred million cells. These cells are then put into recipient animals and humans to study their ability to treat numerous autoimmune diseases such as Parkinson's, multiple sclerosis, crohn's disease, asthma, lupus, to name just a few. These cells are also being studied to treat and regrow damaged heart muscle after a heart attack. Extensive research is being conducted to evaluate the safety and efficacy of utilizing mesenchymal stem cells to treat orthopedic conditions such as osteoarthritis of your joints and disc related chronic back and neck pain.

This has exciting implications for chronic neck and back pain sufferers. These Mesenchymal stem cells could help regenerate tissue in the spine, reversing issues like degenerative disc disease. The stem cells could also decrease pain-causing inflammation and help patients recover from accidents and injuries faster.

If you are a chronic neck or back pain sufferer and would like to learn more about Dr. Pettine's research on Mesenchymal stem cell therapy, visit his website at http://www.KennethPettine.com for more information.

About Dr. Kenneth Pettine Dr. Pettine is currently the principal investigator for 18 FDA studies evaluating non-fusion spine surgery implants and stem cells for their uses in treating spine pathology. He is considered a pioneer in the field of biologics to treat orthopedic and spine pathology. He founded The Rocky Mountain Associates in Orthopedic Medicine in 1991 to offer patients a non-fusion surgical option for their neck and back pain. He co-invented the FDA-approved Prestige cervical artificial disc and the Maverick Artificial Disc. He is currently focused on educating anyone interested in learning about the use of Mesenchymal stem cell therapy.

Rich Garton, CTV Windsor Published Tuesday, March 7, 2017 9:15AM EST Last Updated Tuesday, March 7, 2017 3:50PM EST

A Windsor infant with a rare genetic disorder has found a bone marrow match.

CTV Windsor first brought you Madalayna Ducharme's story a few months ago -- when her parents, Tamara and Charles made a plea for people to become bone marrow and stem cell donors.

It was on the heels of them learning Madalayna suffers from a rare genetic disorder called malignant infantile osteopetrosis. The side effects cause progressive vision and hearing loss, bone density and could potentially be fatal.

Doctors contacted the family this week and Ducharme is already undergoing treatment and is being prepped for the bone marrow transplant.

CTV News spoke with the family -- and they are elated with the news, but the Ducharme's excitement is tempered by a fear of what lies ahead.

We're a little scared at the same time because of the stuff she has to go through, says Tamara Ducharme. She has a regiment she has to go through before she can get this transplant.

That includes heavy doses of chemotherapy, with potential side effects, before a bone marrow transplant can take place.

Chemo is not going to be pretty, says Tamara Ducharme. She's a happy little girl, she cries once in a while like a regular child, she's going to be very ill and I don't know if I'm ready for that."

For now, they will borrow strength from their warrior princess.

Tamara Ducharme took to Facebook this morning to provide the good news. "We are sending big THANKS to all who have supported us, got swabbed, volunteered and donated blood," she posted.

Almost 30 years ago, the federal government helped make it easier for patients with leukemia and lymphoma to receive lifesaving stem cell transplants. Now, we need the federal governments help again to ensure that Medicare patients with these cancers and other serious blood disorders can access the care they need.

In 1987, Congress approved funding for a national database of patients willing to donate bone marrow or peripheral blood stem cells. That database is now known as the Be The Match Registry, operated by the National Marrow Donor Program/Be The Match. According to the NMDP/Be The Match, patients searching the registry have access to 27 million potential volunteer bone marrow and peripheral blood stem cell donors worldwide, along with more than 680,000 units of cord blood donated by mothers after giving birth.

Having access to such a large registry has made it easier for patients to find a match if they dont have a fully matched sibling donor, which is the case for about 70 percent of patients who receive a stem cell transplant. The registry has helped 80,000 patients receive bone marrow transplants, peripheral blood stem cell transplants, or cord blood transplants from an unrelated donor.

While the federal governments foresight and financial support have helped make adult stem cell and cord blood transplants the only cure available for these diseases possible for thousands of patients, Medicare coverage policies have not kept pace with this breakthrough treatment.

Medicare is more restrictive than private insurance companies in deciding for what indications stem cell transplants and cord blood transplants will be covered. With private insurance companies, we have the opportunity to talk with a medical director about the indication and provide literature to support the decision for a transplant. This opportunity is not available for our Medicare patients.

In most cases, Medicare doesnt decide whether to cover a stem cell or cord blood transplant until after the procedure is completed. This leaves most Medicare patients an impossible choice: Turn down their only chance at a cure or potentially face paying the significant cost of a transplant themselves. Even when Medicare does decide to reimburse for these transplants, according to the NMDP/Be The Match, it covers less than half the cost of the transplant.

Addressing this issue is especially important because seniors make up a large portion of the patients with the cancers and blood diseases that can be cured by a stem cell or cord blood transplant. For example, 24 of the 65 patients who received stem cell or cord blood transplants at University of Virginia Health System in 2016 had Medicare coverage.

So I am asking the Centers for Medicare & Medicaid Services to expand Medicare coverage for stem cell and cord blood transplants, along with paying for the search and procurement costs as they already do for solid organ transplants.

The federal government has helped save the lives of tens of thousands of patients through better access to stem cell and cord blood transplants. I hope now they will act to make sure all Medicare patients who need one of these transplants can receive it.

Tamila L. Kindwall-Keller, DO, MS is the associate clinical director of the Stem Cell Transplant Program at the University of Virginia Health System.

Recent advancements in stem cells research have given hope for successfully treating diabetic heart disease (DHD), renowned New Zealand-based researcher in cardiovascular diseases Dr Rajesh Katare said on Tuesday.

DHD affected the muscular tissues of the heart leading to complications and it had been demonstrated that resident stem cells of myocardium can be stimulated to repair and replace e degenerated cardiac myocytes resulting in a novel therapeutic effect and ultimately cardiac regeneration, he said.

Katare, Director of Cardiovascular Research Division in the University of Otago, New Zealand, was delivering the keynote address at the continuing medical education programme on "Role of Micro-RNAs and stem cells in cardiac regeneration in diabetic heart disease" at the Karaikal campus of premier health institute JIPMER.

Presenting clinical evidences, Katare said stem cell therapy certainly presented a new hope for successfully treating DHD.

Jawaharlal Institute of Post Graduate Medical Education (JIPMER) Director Dr Subash Chandra Parija pointed out that it was the first such programme on the role of stem cells in cardiac regeneration in the whole of the country.

He said as diabetes was highly prevalent in the country, providing treatment for DHD had become a big challenge. Patients suffering from the condition have to undergo lifelong treatment and medications. "In this backdrop, advancements in stem cell therapy assume significance," he said. (REOPENS MES10)

Parija also said the government general hospital in

Karaikal being currently used by JIPMER for clinical teaching of students would have upgraded facilities.

He said a new building for the college would be constructed at a cost of Rs 497.10 crore soon.

The proposed up-gradation of the GH having 506 beds would help in imparting advanced clinical teaching and effective exposure of the medicos to various nuances of the diagnosis.

The Director also said JIPMER (Karaikal) had drawn up special post-graduate and fellowship programmes including on family medicine, tropical medicine, trauma care and cancer management.

NBC-5 news anchor Rob Stafford has been diagnosed with a rare blood disorder and will take a leave of absence from the station for several months as he undergoes a bone marrow transplant and chemotherapy.

Stafford credited his wife, Lisa, for pushing him to get an early diagnosis that doctors say greatly improved his prognosis. He is scheduled to begin treatment Friday at the Mayo Clinic in Rochester, Minn.

"I spent my whole life asking questions, but I asked very few questions about my own health because all I wanted to hear is I'm OK," Stafford said in an interview at his Hinsdale home Tuesday. "You have to ask questions."

Stafford told colleagues at WMAQ-Ch. 5 about his illness in an email Wednesday morning and planned to announce the news publicly Wednesday at the end of the 10 p.m. newscast.

He expects to be away from his desk anchoring the 5, 6 and 10 p.m. weekday news for four to six months while at the Mayo Clinic. Doctors there say Stafford is in the early stages, Stage 2, of the disease, which can lead to heart failure and death if undetected.

Stafford's disorder, called amyloidosis, occurs when an abnormal protein called amyloid is produced in bone marrow that can be deposited in tissues and organs. There are more than 40 types of the disorder that affects the heart, kidneys, liver, spleen, nervous system and digestive tract. Stafford's type known as light chain amyloidosis is rare, with fewer than 2,000 or so cases diagnosed in the U.S. each year, according to Dr. Ronald Go, Stafford's hematologist at the Mayo Clinic. Doctors are optimistic he will go into remission after treatment.

Before his diagnosis in January, Stafford had noticed lower energy levels while biking the Cal-Sag trail and hiking through the Rocky Mountains while on vacation. But the 58-year-old award-winning investigative reporter and father of three adult children dismissed the episodes as signs of getting older, he said.

After a physical detected slightly high cholesterol levels and more than usual amounts of protein in his urine, both indicators that his kidney had been damaged as a result of the blood disease, Stafford's wife insisted that he take the symptoms seriously.

"I believe there's a reason that this happened, and I think there's a calling that is to let people know the importance of early detection," said Lisa Stafford, his wife of 30 years who owns a medical marketing and communications company. She plans to stay with Stafford in temporary housing near the Mayo Clinic as he undergoes treatment, lives in a sterile environment and rebuilds his immune system while recovering from the effects of chemotherapy.

In his email to fellow staffers, Stafford joked that he did not wait for the end of sweeps to schedule treatment, but that Friday was the first opening on the Mayo schedule after Stafford completed all the required medical tests.

"I consider this early diagnosis a gift that left to my own devices I would not have received," Stafford wrote. "I'm going to take full advantage of my good fortune and hit this head on with the most aggressive and proven treatment available."

Stafford joined NBC-5 in 2009 after working as a Chicago-based correspondent for Dateline NBC for 11 years. Prior to that, he was a general assignment reporter at CBS2 Chicago. He has won two national and seven local Emmy awards, and an Edward R. Murrow award for a Dateline investigation into racial profiling.

Stafford said his experience meeting and interviewing people in the news, often "on their worst days," has allowed him to keep his health issues in perspective.

"This thing pales in comparison to 95 percent of the stories I do on a daily basis," said Stafford, who added that his work as a journalist also has helped him to seek out the best support, medical opinions and advice about the disorder.

During treatment, doctors will remove, or "harvest," stem cells from Stafford's own bone marrow and freeze millions of healthy ones. Chemotherapy then will be used to wipe out all of his bone marrow, including the unhealthy cells. As the final part of the treatment, doctors will transplant the healthy stem cells back into Stafford's bone marrow, and they will reproduce themselves, Go said.

"You're rescuing your bone marrow by the stem cells that you stored," Go said.

Although Stafford's parents were both treated for cancers in their 50s, doctors do not know the exact cause of Stafford's illness and do not believe it was is hereditary. Risk factors for amyloidosis include exposure to chemicals, radiation and aging, Go said.

Stafford confided in his NBC-5 co-anchor, Allison Rosati, and meteorologist Brant Miller about his illness shortly after his diagnosis in January. As medical tests forced him to travel, he alerted NBC-5 managers, who encouraged Stafford to do whatever it took to get the medical attention needed, he said.

"Rob is loved by his colleagues in the newsroom. We are encouraged by the news that his illness was detected early, and that he is in the excellent hands of the top doctors at the Mayo Clinic. We all wish Rob the best of luck in the weeks ahead, and we can't wait for his return to the newsroom," station manager and vice president of news Frank Whitaker said in an email.

NBC-5 weekend anchor Dick Johnson will be filling in for Stafford during his absence.

Stafford is expected to lose his hair as a result of the chemotherapy and has experienced weight loss. Doctors have encouraged him to pack on a few pounds in anticipation of further weight loss. He's obliged by indulging on Girl Scout cookies, deep dish pizza, cheeseburgers and milk, he said.

Stafford said he is trying to take emotion out of his upcoming battle, which he is approaching as a fight that he plans to win.

"I am not freaking out because I really am confident I am going to get through this," he said.

Lisa Stafford will be posting updates about her husband's condition on a blog: staffordrecovery.com. Rob Stafford also will offer updates on his Facebook Fan page.

Stafford's announcement came less than 24 hours after Hosea Sanders, veteran news anchor at WLS-Ch. 7, announced on his Facebook page he will undergo surgery for prostate cancer and that he was "very optimistic about the outcome."

Sanders told social media friends Tuesday night that he had been diagnosed several weeks ago and would be taking some time off from the ABC-owned station, for which he anchors the 7 p.m. newscast each weeknight.

The California stem cell agency this week approved nearly $33 million for clinical stage research projects testing treatments for type 1 diabetes, arthritis of the knee, ALS and an immunodeficiency affliction.

The awards were quickly approved with little discussion during a meeting at the Oakland headquarters of the California Institute for Regenerative Medicine or CIRM, as the agency is formally known.

The goal of the research is to regenerate knee cartilage through the use of a mesenchymal progenitor cell treatment, according to the agencys application review summary

The award likely to have an impact on the most people if it is successful is a relatively small, $2.3 million award to the Cellular Biomedicine Group, a Chinese firm with operations in Cupertino, Calif. The stem cell agency by law only finances work in Clifornia. The research would also be supported by $572,993 in co-funding.

The project is aimed at treating osteoarthritis of the knee. More than 51 million people in the United States suffer from arthritis, which is particularly common in the knee.

The goal of the research is to regenerate knee cartilage through the use of a mesenchymal progenitor cell treatment, according to the agencys application review summary. The funding would go to manufacture the product and complete work to secure Food and Drug Administration approval for a phase one safety trial. A treatment for the public would likely be years in the future.

Here are the other winners today of California stem cell cash with links to the summaries of the reviews.

Caladrius Biosciences of New Jersey won $12.2 million for a clinical trial for young people ages 12-17 for newly diagnosed type 1 diabetes. The firm plans to use regulatory T cells from the patients themselves to treat the disease. Caladrius has a California location in Mountain View. (Caladrius press release can be found here.)

St. Judes Research Hospital in Memphis, Tenn., was awarded $11.9 million for a phase one/two trial to treat infants with X-linked severe combined immunodeficiency. The trial would aim at enrolling at least six patients suffering from the catastrophic affliction. The treatment would use the patients own bone marrow stem cells after the cells were specially handled. The agency said in a press release that St. Judes is working with UC San Francisco. (St. Judes press release can be found here.)

The awards were previously approved behind closed doors by the agencys out-of-state reviewers, who do not disclose publicly their economic or professional interests.

Cedars-Sinai Medical Center in Los Angeles was awarded $6.2 million for a phase 1/2A trial to test a treatment for ALS, which has no treatment or cure. The CIRM review summary said a huge unmet need existed. About 20,000 persons in the United States suffer from the affliction.

CIRMs press release did not identify the researchers involved in any of the awards.

The agency is on a push to support more clinical trials, which are the last and most expensive research prior to the possibility of winning federal approval for widespread use of a therapy.

Currently the agency is participating in 27 trials and is planning on adding 37 more in the next 40 months. The agency is expected to run out of funds for new awards in June 2020 and has no source of future financing.

The awards were previously approved behind closed doors by the agencys out-of-state reviewers, who do not disclose publicly their economic or professional interests. The agencys directors rarely overturn a positive decision by the reviewers.

All of the winners have links to two or more members of the 29-member CIRM governing board. Those members are not allowed to vote on applications where they have conflicts of interest.

About 90 percent of the funds awarded by the board since 2005 have gone to institutions that have ties to members of the board, past or present, according to calculations by the California Stem Cell Report. Eds Note: David Jensen is a retired newsman who has followed the affairs of the $3 billion California stem cell agency since 2005 via his blog, the California Stem Cell Report, where this story first appeared. He has published more than 4,000 items on California stem cell matters in the past 11 years.

Stem cell: Knee arthritis in new $33 million research plan - Capitol Weekly

The mystery of what controls the range of developmental clocks in mammals -- from 22 months for an elephant to 12 days for a opossum -- may lie in the strict time-keeping of pluripotent stem cells for each unique species.

Developmental clocks are of high importance to regenerative medicine, since many cells types take long periods to grow to maturity, limiting their usefulness to human therapies. The regenerative biology team at the Morgridge Institute for Research, led by stem cell pioneer and UW-Madison professor James Thomson, is studying whether stem cell differentiation rates can be accelerated in the lab and made available to patients faster.

In a study published in February online editions of the journal Developmental Biology, Morgridge scientists tested the stringency of the developmental clock in human stem cells during neural differentiation. First, they closely compared the differentiation rates of the cells growing in dishes compared to the known growth rates of human cells in utero. Second, they grew the human stem cells within a mouse host, surrounded by factors -- such as blood, growth hormones and signaling molecules -- endemic to a species that grows much more rapidly than humans.

In both cases -- lab dish or different species -- the cells did not waver from their innate timetable for development, without regard to environmental changes.

"What we found remarkable was this very intrinsic process within cells," said lead author Chris Barry, a Morgridge assistant scientist. "They have self-coding clocks that do not require outside stimulus from the mother or the uterus or even neighboring cells to know their pace of development."

While the study suggests that cellular timing is a stubborn process, the Thomson lab is exploring a variety of follow-up studies on potential factors that could help cells alter their pace, Barry said.

One aspect of the study that's immediately valuable across biology is the realization that how stem cells behave in the dish aligns almost precisely with what happens in nature.

"The promising thing is that we can take species of stem cells, put them in tissue culture, and more confidently believe that events we're seeing are probably happening in the wild as well," Barry said. "That is potentially great news for studying embryology in general, understanding what's going on in the womb and disease modeling for when things can go wrong."

It also opens up potential avenues in embryology that would have been inconceivable otherwise -- for example, using stem cells to accurately study the embryology of whales and other species with much longer (or shorter) gestation rates than humans.

In order to accurately compare development timing across species with wildly different gestation rates -- nine months compared to three weeks -- the team used an algorithm called Dynamic Time Warping, originally developed for speech pattern recognition. This algorithm will stretch or compress the time frame of one species to match up with similar gene expression patterns in the other. Using this process, they identified more than 3,000 genes that regulate more rapidly in mice and found none that regulate faster in human cells.

The impact of solving the cell timing puzzle could be enormous, Barry said. For example, cells of the central nervous system take months to develop to a functional state, far too long to make them therapeutically practical. If scientists can shorten that timing to weeks, cells could potentially be grown from individual patients that could counteract grave diseases such as Parkinson's, Multiple Sclerosis, Alzheimer's, Huntington's disease and spinal cord injuries.

"If it turns out these clocks are universal across different cell types," said Barry, "you are looking at broad-spectrum impact across the body."

The mystery of what controls the range of developmental clocks in mammals -- from 22 months for an elephant to 12 days for an opossum -- may lie in the strict time-keeping of pluripotent stem cells for each unique species.

Developmental clocks are of high importance to regenerative medicine, since many cell types take long periods to grow to maturity, limiting their usefulness to human therapies. The regenerative biology team at the Morgridge Institute for Research, led by stem cell pioneer and University of Wisconsin-Madison Professor James Thomson, is studying whether stem cell differentiation rates can be accelerated in the lab and made available to patients faster.

In a study published in February online editions of the journal Developmental Biology, Morgridge scientists tested the stringency of the developmental clock in human stem cells during neural differentiation. First, they closely compared the differentiation rates of the cells growing in dishes compared to the known growth rates of human cells in utero.

KARAIKAL: Recent advancements in stem cells research have given hope for successfully treating diabetic heart disease (DHD), renowned New Zealand-based researcher in cardiovascular diseases Dr Rajesh Katare said today.

DHD affected the muscular tissues of the heart leading to complications and it had been demonstrated that resident stem cells of myocardium can be stimulated to repair and replace e degenerated cardiac myocytes resulting in a novel therapeutic effect and ultimately cardiac regeneration, he said.

Katare, Director of Cardiovascular Research Division in the University of Otago, New Zealand, was delivering the keynote address at the continuing medical education programme on "Role of Micro-RNAs and stem cells in cardiac regeneration in diabetic heart disease" at the Karaikal campus of premier health institute JIPMER.

Presenting clinical evidences, Katare said stem cell therapy certainly presented a new hope for successfully treating DHD.

Jawaharlal Institute of Post Graduate Medical Education (JIPMER) Director Dr Subash Chandra Parija pointed out that it was the first such programme on the role of stem cells in cardiac regeneration in the whole of the country.

He said as diabetes was highly prevalent in the country, providing treatment for DHD had become a big challenge. Patients suffering from the condition have to undergo lifelong treatment and medications. "In this backdrop, advancements in stem cell therapy assume significance," he said.

About TiGenix

TiGenix NV (Euronext Brussels: TIG) is an advanced biopharmaceutical company focused on developing and commercializing novel therapeutics from its proprietary platforms of allogeneic, or donor-derived, expanded stem cells. Our lead product candidate from the adipose-derived stem cell technology platform is Cx601, which is in registration with the European Medicines Agency for the treatment of complex perianal fistulas in Crohn's disease patients. Our adipose-derived stem cell product candidate Cx611 has completed a Phase I sepsis challenge trial and a Phase I/II trial in rheumatoid arthritis. Effective July 31, 2015, TiGenix acquired Coretherapix, whose lead cellular product candidate, AlloCSC-01, is currently in a Phase II clinical trial in Acute Myocardial Infarction (AMI). In addition, the second product candidate from the cardiac stem cell-based platform acquired from Coretherapix, AlloCSC-02, is being developed in a chronic indication. On July 4, 2016, TiGenix entered into a licensing agreement with Takeda, a large pharmaceutical company active in gastroenterology, under which Takeda acquired the exclusive right to commercialize Cx601 for complex perianal fistulas outside the United States. TiGenix is headquartered in Leuven (Belgium) and has operations in Madrid (Spain).

About Cx601

Cx601 is a suspension of allogeneic expanded adipose-derived stem cells (eASC) locally injected. Cx601 is an investigational agent being developed for the treatment of complex perianal fistulas in Crohn's disease patients with inadequate response to at least one conventional or biologic therapy including antibiotics, immunosuppressants, or anti-TNF agents. Crohn's disease is a chronic inflammatory disease of the intestine and patients can suffer from complex perianal fistulas for which there is currently no effective treatment. In 2009, the European Commission granted Cx601 orphan designation for the treatment of anal fistulas, recognizing the debilitating nature of the disease and the lack of treatment options. Cx601 has met the primary end-point in the Phase III ADMIRE-CD study in Crohn's disease patients with complex perianal fistula, a randomized, double-blind, placebo-controlled trial run in Europe and Israel and designed to comply with the requirements laid down by the EMA. 'Madrid Network' issued a soft loan to help finance this Phase III study, which was funded by the Secretary of State for Research, Development and Innovation (Ministry of Economy and Competitiveness) within the framework of the INNTEGRA plan. The study's primary endpoint was combined remission, defined as clinical assessment at week 24 of closure of all treated external openings draining at baseline despite gentle finger compression, and absence of collections >2cm confirmed by MRI. In the ITT population (n=212), Cx601 achieved statistically significant superiority (p=0.024) on the primary endpoint with 50% combined remission at week 24 compared to 34% in the placebo arm. Efficacy results were robust and consistent across all statistical populations. Treatment emergent adverse events (non-serious and serious) and discontinuations due to adverse events were comparable between Cx601 and placebo arms. The 24-weeks results have been published by The Lancet, one of the most highly regarded and well known medical journals in the world. The Phase III study has completed a follow-up analysis at 52 weeks confirming its sustained efficacy and safety profile. Top line follow-up data showed that in the ITT population Cx601 achieved statistical superiority (p=0.012) with 54% combined remission at week 52 compared to 37% in the placebo arm. The 52-week data also showed a higher rate of sustained closure in those patients treated with Cx601 and in combined remission at week 24 (75.0%) compared to patients in the placebo group (55.9%). Based on the positive 24-weeks Phase III study results, TiGenix has submitted a Marketing Authorization Application to the EMA in early 2016. TiGenix is preparing to develop Cx601 in the U.S. after having reached an agreement with the FDA through a special protocol assessment procedure (SPA) in 2015. On July 4, 2016 TiGenix entered into a licensing agreement with Takeda, a pharmaceutical company leader in gastroenterology, whereby Takeda acquired an exclusive right to commercialize Cx601 for complex perianal fistulas in Crohn's patients outside of the U.S.

Johns Hopkins Medicine doctors have treated the first person in a key phase of a clinical trial where a high dose of the patient's own bone marrow cells was used to treat heart failure after a heart attack.

The dose was directed precisely at the point of dysfunction in the heart in the hope that it will stimulate the body's natural healing process.

The Hopkins patient was the first to receive what is called the CardiAMP therapy as part of the third phase of a trial taking place at 40 medical centers across the country. Once phase three trials show a treatment works well, doctors can apply for approval with the Food and Drug Administration.

BioCardia, Inc., headquartered in San Carlos, CA., developed the therapy and The Maryland Stem Cell Research Fund provided research money. The fund was created by the Maryland General Assembly in 2006 to promote state-funded stem cell research and cures through grants and loans to public and private entities.

"Funding the clinical trial of this cell therapy, which could be the first cardiac cell therapy approved in the United States, is an important step towards treatments," Dan Gincel, executive director of the Maryland Stem Cell Research Fund, said in a statement. "Through our clinical program, we are advancing cures and improving health care in the State of Maryland."

Heart disease is the number one killer in the United States. About 610,000 people die from heart disease every year and it accounts for one in every four deaths, according to the Centers for Disease Control and Prevention.

The first patient was treated at Johns Hopkins Hospital by a team led by Peter Johnston, faculty member in the Department of Medicine and Division of Cardiology, and principal investigator of the trial at Johns Hopkins.

Patient's own bone marrow used to treat heart failure - Baltimore Sun (blog)

Researchers at the Universit libre de Bruxelles, ULB define for the first time the changes in the stem cell dynamics that contribute to wound healing.

One of the key questions in biology is to identify how tissues are repaired after trauma and understand how stem cells migrate, proliferate, and differentiate to repair tissue damage.

In a study published in Nature Communications, researchers lead by Pr. Cdric Blanpain, MD/PhD, WELBIO investigator, and Professor at the Universit libre de Bruxelles, Belgium, defined the cellular and molecular mechanisms that regulate wound healing in the skin.

The skin is the first barrier protecting the animals against the external environment. When the skin barrier is disrupted, a cascade of cellular and molecular events is activated to repair the damage and restore skin integrity. Defects in these events can lead to improper repair causing acute and chronic wound disorders. In the skin, distinct stem cells populations contribute to wound healing. However, it remains unclear how these different stem cells populations balance proliferation, differentiation and migration during the healing process.

In this new study published in Nature Communications, Mariaceleste Aragona, Sophie Dekoninck and colleagues define the clonal dynamics and the molecular mechanisms that lead to tissue repair in the skin epidermis. They used state of the art genetic mouse models to study different stem cells populations. Specifically, they use a technique called lineage tracing to mark stem cells and follow the fate of their progeny over time. Interestingly, they found that stem cells coming from different epidermal compartments present very similar response during wound repair, despite the fact that they are recruited from different regions of the epidermis. It was particularly exciting to observe that the repair of the skin epidermis involves the activation of very different stem cells that react the same way to the emergency situation of the wound and have the power to completely restore the damaged tissue, comments Mariaceleste Aragona, the first author of the study. The authors defined the gene signature of the different regions surrounding the wound to uncover the gene expression signature of the cells that actively divide and those that migrate to repair the wound. The molecular characterization of the migrating leading edge suggests that these cells are protecting the stem cells from the infection and mechanical stress allowing a harmonious healing process, comments Sophie Dekoninck, the co-first author of the study.

Altogether, this study provides important insights into the changes in the mechanisms that lead to tissue repair, and demonstrates that the capacity of the stem cells to regenerate a tissue does not depend on their cellular origin but rather on their proliferation capacity.

This new study uncovers for the first time the dynamic of stem cells during wound healing and identifies new molecular players associated with skin regeneration. The deregulation of several of these genes in patients with chronic ulcers, suggest that defects in the formation and/or function of these two different structures may induce defect of wound-healing leading to chronic ulcer formation. Further functional studies will be needed to define the role of these genes and to identify new therapeutic targets to treat chronic wound disorders that cost each year billions of dollars, explains Cdric Blanpain, the senior and corresponding author of this new study.

With MLB spring training underway, there's plenty to talk about. USA TODAY Sports

Garrett Richards is aiming to pitch through a ligament tear via stem cell therapy and other recovery methods.(Photo: Rick Scuteri, USA TODAY Sports)

TEMPE, Ariz. Garrett Richards first thought when he found out about his torn elbow ligament last May was to schedule Tommy John surgery as soon as possible.

It made sense, considering the ligament-replacement procedure has become the standard fix for such injuries. Plus, the Los Angeles Angels ace was familiar with the operating room, having undergone surgery for a ruptured patellar tendon he sustained on Aug. 20, 2014, toward the end of a breakout season.

Richards knew how to handle the seemingly interminable months of rehab, and he wanted to get the clock started on his return.

But a conversation with Angels head physical therapist Bernard Li convinced Richards to consider other alternatives, and in mid-May he tried a relatively novel treatment in which stem cells taken from bone marrow in his pelvis were injected into the damaged area.

Richards did not pitch again the rest of the year except for a stint in the instructional league, but he has been back on the mound throwing bullpen sessions since the first day of the Angels camp and reported no problems.

This weekend, Richards anticipates pitching in a game for the first time since May 1, when his aching elbow forced him from a start after just four innings.

Its nice to know Ill be able to start the season this year and kind of pick up where I left off, Richards said.

A couple of lockers away, fellow starter Andrew Heaney had a different tale to tell.

Royals know the deal: Win now, or say goodbye

One burning question facing every AL team

Tim Tebow reports to Mets camp ready for 'hardest thing in sports'

The promising left-hander also went down with a torn ulnar collateral ligament early in the season, after making only one start. Their ailments were the two biggest blows to an Angels rotation that was decimated by injuries, dooming the club to a 74-88 record and a fourth-place finish in the AL West.

Heaney also tried stem cell therapy, two weeks before Richards, both under the supervision of team doctor Steve Yoon. Heaneys ligament didnt heal, though, and after experiencing discomfort throwing following his rehab, he had Tommy John surgery July 1. He has been ruled out for the 2017 season.

They tell you its 50-50. It either works or it doesnt, Heaney said of the stem cell procedure. Obviously, me and Garrett are pretty much the proof of that rule.

Even with less-favorable odds than reconstructive surgery, which has an 80% success rate for returning to action and 67% for pitching 10 games or more, stem cell therapy is gaining acceptance as an option for pitchers with partial UCL tears. The recovery time is shorter 3-5 months instead of 12-18 and the treatment less invasive.

There are limitations. Biological approaches based on stem cells or platelet-rich plasma (PRP) wont repair a complete tear of the ligament. The location of the injury and its extent factor into the chances of success. And players whose ligament doesnt recover, then have to undergo surgery, extend their window of time for returning to action.

Even then, the idea of healing without going under the knife is becoming increasingly appealing. New York Yankees ace Masahiro Tanaka treated the small tear in his elbow ligament with PRP and rehabilitation in 2014, sitting out 10 weeks but coming back to pitch in late September.

Hes 26-11 with a 3.26 ERA over the last two seasons, raising the profile of PRP a procedure in which the players own blood is used to promote healing of the injury as a non-surgical alternative.

Now Richards looms as the test case for stem cell treatment to fix partial UCL tears, which make up about 60-70% of these injuries. If the hard-throwing right-hander can return to his old form he was a Cy Young Award candidate before his knee injury in August 2014 other pitchers in his situation are bound to at least consider the route he took.

I hope this opens another path for guys, Richards said. Obviously, if you can prevent being cut on and having surgery, thats the No. 1 priority. I hope guys dont just jump right into Tommy John, that they at least explore this option.

Ageless veteran Bartolo Colon was the first pitcher widely known to have undergone stem cell therapy as he sought to recover from elbow and shoulder ailments in 2010. At the time, the ethics of the procedure were questioned, especially because the doctor who performed it, South Florida-based Joseph Purita, acknowledged using human growth hormone in previous treatments, though not in Colons.

Since then, the use of stem cells has become more mainstream. They are the focus of Yoons practice.

As more and more people start to use it, youre getting a better sense for what it can and cant do, Yoon said. Baseball definitely has opened up to it quite a bit, and as we see some of the successes like with Garrett, were getting a better understanding that theres a lot of potential here with these types of treatment.

Yoon calls stem cell therapy a super PRP because it combines the curative properties of that treatment with more healing agents, and said it can be used on tendon tears, muscle tears and strains and even to address degenerative joint disease.

However, much remains unknown about the benefits of stem cells. Lyle Cain, an orthopedist who has performed both Tommy John surgeries and stem cell treatments at the Andrews Sports Medicine & Orthopaedic Center in Birmingham, Ala., said most of the research has been anecdotal, not scientific.

We still dont have a good understanding even four or five years into it exactly what the stem cells do, what their method is, Cain said. The theory is theres probably a chemical reaction where it releases chemicals in the cell that help the healing process. The stem cells arent necessarily put in there with the thought theyre going to become ligament, but theres probably a cellular chemical mechanism that helps the healing response.

And as Heaney discovered, theyre not always effective. His tear was located farther down the arm, which reduced his chances of success with stem cell therapy. Richards was a better candidate because his injury, though deemed high grade, was located within the ligament, like a slit on a rubber band.

But because Heaney was looking at likely missing most or all of 2017 even if he had surgery right away, he decided to try stem cells. The timing of the injury plays a major role in whether pitchers contemplate alternatives to surgery, with the more conservative approach often recommended if it happens early in the season.

Heaney said he doesnt regret taking that route, and would have been upset if he had undergone the ligament-replacement operation right away, only to find out he could have returned to action quicker through another means.

Im glad it worked for him, he said of Richards. It would have been really awful if it hadnt worked for either of us. Then wed both look like idiots.

Their peers are paying attention. In a major league pitching community where about a quarter of its members have undergone Tommy John surgery, interest in the effectiveness of alternative cures is high.

The Los Angeles Dodgers Brandon McCarthy was not a candidate because his ligament tore clear off the bone, but said he had heard positive reports about stem cell treatment, not so much about PRP.

The Pittsburgh Pirates Daniel Hudson, a veteran of two Tommy Johns, is encouraged as well.

Its supposed to help repair the tissue. Before, ligaments just wont repair themselves, Hudson said. It might keep a lot of guys from going under the knife.

Thats Cains hope. He regularly treats UCL tears on high school, college and minor-league players with stem cells or PRP, but realizes theres heightened pressure on major leaguers to return to the field.

If more of them can do it without visiting an operating room, it would represent a major advancement for both the players and the industry.

I think overall the biologic treatment of these injuries will certainly progress and it will be somewhat the wave of the future, Cain said. There will be certain ligaments that are damaged enough that we dont have an answer; they have to reconstruct. But I think overall, if you look 15 years down the road, I suspect well be doing a lot more non-surgical treatment than surgical treatment.

A high-level meeting has paved the way for global trials to begin on hundreds of patients.

British scientists have found a way to use stem cells to repair damaged tissue which could help millions living with heart failure, the UKs leading cause of death.

Scarring due to disease or heart attacks affects more than two million people in Britain.

This would be the biggest breakthrough since the first transplants three decades ago

Professor Steve Westaby

Initial trials involving more than 100 patients are being planned for the autumn at two London hospitals.

World renowned cardiac surgeon Professor Steve Westaby, who helped pioneer the revolutionary technique, said it had been thought that repairing heart damage was impossible.

But results from a long-term trial that began in Greece five years ago have shown that this is not the case.

Preliminary data from this trial showed the engineered stem cells, known as Heartcel, can reverse scarring by up to 79 per cent.

The data, presented at the European Society of Cell and Gene Therapy in Florence, showed an average of 40 per cent reduction in heart damage in those on the treatment.

Last month researchers finalised talks with European and US regulators to discuss the timetable for global trials next year involving 500 people.

6 early signs of a heart attack

Professor Westaby, from the John Radcliffe Hospital, Oxford, said: I am very excited at the prospect of a trial which will hopefully lead to the availability of this stem cell treatment to thousands of patients annually in the UK.

Other scientists have tried in vain to repair damaged heart muscle using stem cells over the past few decades.

This is the first time scarring has been shown to be reversible. It could herald an end to transplants and lead to a treatment for heart failure within three to five years.

GETTY

Professor Westaby said: This would be the biggest breakthrough since the first transplants three decades ago.

Professor Westaby has been working on the technique for more than a decade and is carrying out the study with Professor Kim Fox, head of the National Heart and Lung Institute, at Imperial College London.

The implanted stem cells were created by medical outfit Celixir, co-founded by Nobel laureate Professor Martin Evans, the first scientist to culture mice embryonic stem cells in a laboratory.

Professor Westaby was inspired to work on the breakthrough in 1999 after a four-month-old baby girls heart healed itself after he carried out a major life-saving operation.

Kirsty Collier, from Swindon, was dying of a serious and rare heart defect. In a last ditch effort Professor Westaby cut away a third of her badly damaged heart.
