Will stem cell therapy help cure spinal cord injury?

A systematic survey of the scientific literature shows that stem cell therapy can have a statistically significant impact on animal models of spinal cord injury, and points the way for future studies.
Spinal cord injuries are mostly caused by trauma, often incurred in road traffic or sporting incidents, often with devastating and irreversible consequences, and unfortunately having a relatively high prevalence (250,000 patients in the USA; 80% of cases are male). High-profile campaigners like the late actor Christopher Reeve, himself a victim of sports-related spinal cord injury, have placed high hopes in stem cell transplantation. But how likely is it to work?
This question is addressed in a paper published 17th December in the open access journal PLOS Biology by Ana Antonic, David Howells and colleagues from the Florey Institute and the University of Melbourne, Australia, and Malcolm MacLeod and colleagues from the University of Edinburgh, UK.
Stem cell therapy aims to use special regenerative cells (stem cells) to repopulate areas of damage that result from spinal cord injuries, with the hope of improving the ability to move ("motor outcomes") and to feel ("sensory outcomes") beyond the site of the injury. Many studies have been performed that involve animal models of spinal cord injury (mostly rats and mice), but these are limited in scale by financial, practical and ethical considerations. These limitations hamper each individual study's statistical power to detect the true effects of the stem cell implantation.
This new study gets round this problem by conducting a "meta-analysis" a sophisticated and systematic cumulative statistical reappraisal of many previous laboratory experiments. In this case the authors assessed 156 published studies that examined the effects of stem cell treatment for experimental spinal injury in a total of about 6000 animals.
Overall, they found that stem cell treatment results in an average improvement of about 25% over the post-injury performance in both sensory and motor outcomes, though the results can vary widely between animals. For sensory outcomes the degree of improvement tended to increase with the number of cells introduced scientists are often reassured by this sort of "dose response", as it suggests a real underlying biologically plausible effect.
The authors went on to use their analysis to explore the effects of bias (whether the experimenters knew which animals were treated and which untreated), the way that the stem cells were cultured, the way that the spinal injury was generated, and the way that outcomes were measured. In each case, important lessons were learned that should help inform and refine the design of future animal studies. The meta-analysis also revealed some surprises that should provoke further investigation there was little evidence of any beneficial sensory effects in female animals, for example, and it didn't seem to matter whether immunosuppressive drugs were administered or not.

Brittle-bone babies helped by fetal stem cell grafts

Contact: Press Office pressinfo@ki.se 46-852-486-077 Karolinska Institutet
Osteogeneis imperfecta (OI) is a congenital bone disease that causes stunted growth and repeated, painful fracturing. Ultrasound scans can reveal fractures already in the fetus, and now an international team of researchers from Sweden, Singapore and Taiwan have treated two babies in utero by injecting bone-forming stem cells. The longitudinal results of the treatment are published in the journal Stem Cells Translational Medicine.
The babies were treated with mesenchymal stem cells, connective tissue cells that can form and improve bone tissue. The stem cells were extracted from the livers of donors and although they were completely unmatched genetically, there was no rejection and the transplanted cells were accepted as self.
Back in 2005, a paper was published from Karolinska Institutet in Sweden describing how stem cells were given to a female fetus. The present study describes how the girl suffered a large number of fractures and developed scoliosis up to the age of eight, whereupon the researchers decided to give her a fresh stem cell graft from the same donor. For the next two years the girl suffered no new fractures and improved her growth rate. Today she takes dance lessons and participates more in PE at school.
Another unborn baby with OI, a girl from Taiwan, was also given stem cell transplantation by the Karolinska Institutet team and their colleagues from Singapore. The girl subsequently followed a normal and fracture-free growth trajectory until the age of one, when it levelled off. She was given a fresh stem cell treatment and her growth resumed. The girl started to walk and has since not suffered any new fractures. Today she is four years old.
"We believe that the stem cells have helped to relieve the disease since none of the children broke bones for a period following the grafts, and both increased their growth rate," says study leader Dr Cecilia Gtherstrm, researcher at Karolinska Institutet's Department of Clinical Sciences, Intervention and Technology. "Today, the children are doing much better than if the transplantations had not been given. OI is a very rare disease and lacks effective treatment, and a combined international effort is needed to examine whether stem cell grafts can alleviate the disease."
The researchers have also identified a patient, a boy from Canada, who was born with OI caused by exactly the same mutation as the Swedish girl had. The boy was not given stem cell therapy and was born with severe and widespread bone damage, including numerous fractures and kyphosis of the thoracic vertebrae, which causes such over-curvature of the spine that it impairs breathing. The boy died of pneumonia within his first 5 months.
Participating institutions in Singapore have been the National University Hospotal, and the KK Women's and Children's Hospital. Collaborating partner of Taiwan was the Chang Gung Memorial Hospital in Linkou. Researchers of several universities and hospitals in Sweden, Canada and the USA also took part in the work. The study was financed with a grant from the Swedish Society for Medical Research, and two of the participating researchers received a salary from the Singaporean Ministry of Health.

Stem-Cell Therapy and Repair after Heart Attack and Heart Failure
Posted: December 16, 2013 at 4:45 am
Stem Cell Therapy: Helping the Body Heal Itself
Stem cells are natures own transformers. When the body is injured, stem cells travel the scene of the accident. Some come from the bone marrow, a modest number of others, from the heart itself. Additionally, theyre not all the same. There, they may help heal damaged tissue. They do this by secreting local hormones to rescue damaged heart cells and occasionally turning into heart muscle cells themselves. Stem cells do a fairly good job. But they could do better for some reason, the heart stops signaling for heart cells after only a week or so after the damage has occurred, leaving the repair job mostly undone. The partially repaired tissue becomes a burden to the heart, forcing it to work harder and less efficiently, leading to heart failure.
Initial research used a patients own stem cells, derived from the bone marrow, mainly because they were readily available and had worked in animal studies. Careful study revealed only a very modest benefit, so researchers have moved on to evaluate more promising approaches, including:
No matter what you may read, stem cell therapy for damaged hearts has yet to be proven fully safe and beneficial. It is important to know that many patients are not receiving the most current and optimal therapies available for their heart failure. If you have heart failure, and wondering about treatment options, an evaluation or a second opinion at a Center of Excellence can be worthwhile.
Randomized clinical trials evaluating these different approaches typically allow enrollment of only a few patients from each hospital, and hence what may be available at the Cleveland Clinic varies from time to time. To inquire about current trials, please call 866-289-6911 and speak to our Resource Nurses.
Cleveland Clinic is a large referral center for advanced heart disease and heart failure we offer a wide range of therapies including medications, devices and surgery. Patients will be evaluated for the treatments that best address their condition. Whether patients meet the criteria for stem cell therapy or not, they will be offered the most advanced array of treatment options.

West Coast Stem Cell Clinic, Telehealth, Now Offering Stem Cell Injections for Plantar Fasciitis
Posted: December 16, 2013 at 4:45 am
Orange County, California (PRWEB) December 16, 2013
Top California stem cell clinic, TeleHealth, is now offering stem cell injections for plantar fasciitis. The condition may lead to chronic pain and may not respond to traditional treatments, with the stem cell therapy often allowing for pain relief and the ability to avoid the need for surgery. For more information and scheduling, call (888) 828-4575.
Planter fasciitis affects millions of Americans. The condition leads to chronic heel pain and may make it difficult to participate in recreational activities and even walk normally. Traditional treatments such as physical therapy, NSAIDS, steroid injections and orthotics are often effective over time. However, the condition may not respond as desired to these options and stem cells for plantar fasciitis may be the answer.
Therefore, stem cell injections that TeleHealth provides may offer an excellent option for healing the inflamed area while at the same time providing considerable pain relief. The conventional pain management treatments tend to mask pain, however, they do not actually heal the condition directly.
Regenerative medicine treatments with stem cells maintain the potential of actually healing the damaged tissue to provide long term relief. Telehealth has multiple US Board Certified doctors who have a long history of providing stem cell therapy for numerous conditions including degenerative arthritis, rotator cuff and Achilles tendonitis, ligament injury, elbow soft tissue tendinitis and more.
For those suffering from planter fasciitis or any of the other arthritic or soft tissue injury conditions, call TeleHealth at (888) 828-4575.

Parkinson’s stem cell project aims for 2014 approval
Posted: December 14, 2013 at 8:49 pm

Parkinson's patient Ed Fitzpatrick speaks about stem cell research for his disease. Fitzpatrick talked on a Dec. 7 panel at the World Stem Cell Summit in San Diego.
For eight local Parkinsons patients seeking treatment with stem cell technology, 2014 could bring the milestone theyve been anticipating.
If all goes well, the U.S. Food and Drug Administration will approve an attempt to replace the brain cells destroyed in Parkinsons. The new cells, grown from each patients own skin cells, are expected to restore normal movement in the patients.
Because the new brain cells are made from the patients own cells, immunosuppressive drugs shouldnt be needed. Ideally, patients could stop taking their medications and resume normal activities for many years, or even the rest of their lives.
The project, Summit4StemCell.org, is a collaboration between three nonprofits. The Scripps Research Institute handles the science; Scripps Clinic takes care of the medical side; and the Parkinsons Association of San Diego helps to raise money for the self-funded project.
Since 2011, the focus has been at the institute, where scientists led by Jeanne Loring have made the artificial embryonic stem cells, called induced pluripotent stem cells, and turned them into the needed brain cells. Now Scripps Clinic is assuming a more prominent role to prepare for treating the patients.
A study in rats began in early December; results are expected by April. The animal study is meant to assess safety, although researchers will also look for signs of effectiveness.
In January, scientists will visit the FDA to lay the groundwork for a formal application, said Scripps Clinic neurologist Melissa Houser, who treats all eight patients.
Success in the animal study will likely result in a go-ahead, Houser said. If the animal trial fails, its back to the drawing board.

San Diego Canine Overcomes Pain to Achieve Championship with the Help of Paradise Veterinary Hospital and Vet-Stem, Inc.
Posted: December 13, 2013 at 6:42 pm
Poway, California (PRWEB) December 13, 2013
Noni is a ten-year-old released Canine Companion for Independence dog who just achieved her Master Agility Champion status after the pain from arthritis tried to slow her down. Nonis owner, Dr. Kim Dembinski, a veterinarian at Paradise Veterinary Hospital in San Diego turned to stem cell therapy by Vet-Stem, Inc. and fellow colleague Dr. Jennipher Harris to help Noni.
When Dr. Dembinski noticed weakness and discomfort in her aging agility dog she was proactive in keeping Noni happy and comfortable, The main thought was that she gives so much between therapy work, being my best friend, and as the clinic mascot that giving her relief from pain and her being more comfortable was the least I could do for her.
Nonis stem cell therapy involved a small fat sample collection, which was brought to Vet-Stems lab in Poway, California. There, highly trained lab technicians processed Nonis fat tissue to isolate the stem cells into doses that could be injected into the arthritic joints that were causing her pain. Normally the tissue is shipped overnight to Vet-Stem and the cells are shipped overnight back to the veterinarian making doses available within 48 hours, but because Paradise Veterinary Hospital is located near Vet-Stem Nonis stem cell doses were available for injection the same day the fat sample was collected.
Noni did very well post procedure; she regained muscle strength and flexibility, Dr. Dembinski reported, Noni did four weeks of rehab then went right back to competing in agility. Six months after the procedure she earned her MACH (Master Agility Champion), AKC (American Kennel Club) title. Because of her stem cell therapy she is still comfortable and playing agility!
Dr. Dembinski is a general practitioner for pets including dogs, cats, small mammals, birds and exotics. She is currently owner and primary veterinarian at Paradise Veterinary Hospital and sits on the board of the San Diego County Veterinary Medical Association. Caring for animals is not just a job for Dr. Dembinski, it is a passion. In her free time she and Noni compete in dog agility trials with AKC, North American Dog Agility Council and Canine Performance Events.
About Vet-Stem, Inc. Vet-Stem, Inc. was formed in 2002 to bring regenerative medicine to the veterinary profession.

California’s Stem-Cell Quest Races Time as Money Dwindles
Posted: December 12, 2013 at 11:42 pm
Californias government-run stem-cell research agency, on course to spend $3 billion in taxpayer money to find treatments for some of the worlds most intractable diseases, is pushing to accelerate human testing before its financing runs out.
For the California Institute for Regenerative Medicine, time is growing short to fund research that demonstrates the potential of stem cells to help treat everything from cancer to heart disease to spinal cord injuries.
The agency, created by voters in 2004, has given out more than half of its $3 billion from state bonds and must spend the rest by 2017. The largest U.S. funding source for stem-cell research outside the federal government, its under pressure to show results to attract new money from pharmaceutical companies, venture capitalists or even more municipal bonds.
We need to figure out how to keep them going, said Jonathan Thomas, a founding partner of Saybrook Capital LLC in Los Angeles, and chairman of the institutes board, which meets today. We could do public-private partnerships, venture philanthropy, a ballot box.
Embryonic stem cells have the potential to change into any type of cell in the body. They are among the first cells created in embryos after conception. Scientists hope they may replace damaged or missing tissue in the brain, heart and immune system.
California voters approved the bonds after President George W. Bush banned the use of federal funds for research on embryonic stem cells. Since then, other types of stem cells have been shown to act like embryonic cells, relieving some of the debate over the ethics of destroying human embryos to use the cells.
The agencys funding decisions have included a grant of $20 million to a team led by Irv Weissman at the Stanford University School of Medicine, seeking a cure for cancer.
Weissmans team is working on an antibody manufactured with stem cells that allows a cancer patients own immune system to destroy a tumor, instead of relying on toxic radiation or chemotherapy. The antibody counteracts a protein called CD47, which creates what scientists call a dont eat me shield around the cancer. Once that cloak is removed, the patients immune system recognizes the cancer and attacks the tumor, shrinking or eliminating it.
Tests on humans are to begin early next year. The antibody has already worked in mice against breast, colon, ovarian, prostate, brain, bladder and liver cancer.
Two other research projects funded by the California agency are in human trials now -- one targeting HIV, the virus that causes AIDS, and another that regrows cardiac tissue in heart-attack victims.
