IS THE FDA FINALLY, PUBLICLY, GETTING INTO STEM CELLS?
Better late than never…14 years after serious adult stem cell research began in other parts of the world, the FDA finally woke up and they are beginning, BEGINNING to research adult stem cells. They even made a positive statement about their regenerative promise. We’ll call this one a victory in that the outcry for adult stem cells has been so loud, the FDA finally relented and have begun research. Better late than never. Thanks for coming to the party FDA…

But…14 years late to the party. Reminds me of the last scene in Schindler’s list. How many lives could have been saved? How much suffering could have been eased. Well, let’s do the math.

“…in 2005 there were 2,448,000 deaths in the u.s.
4 of the top 6 killers were:

Heart disease (652,000 deaths)
Cancer (559,000 deaths)
Stroke (143,000 deaths)
Diabetes (75,000 deaths)

There were a total of 1,429,000 deaths in 2005 from these 4 diseases and there are renowned stem cell treatment centers around the world that have been successfully treating patients with these disease for years. Around the world, people with these disease are actively receiving asc treatments and benefiting from them.

How many of those 1,429,000 deaths in the USA Could have been averted with asc treatment? How many of those 1,429,000 lives in the u.s. Could have been extended with asc treatment until other treatments were available? We’ll never know. Maybe we could have saved 30% of those people with asc or 428,700 people per year. Over 10 years that might amount to 4,287,000 people saved.

Saving 10% = 142,900 per year or 1,429,000 people saved in 10 years.
Even saving just 2% = 28,580 people per year amounts to 285,800 over 10 years.” [With a potential of 15,000,000 saved over 10 years.]

So when the FDA starts tooting their horn about showing up to the party, doing great research, working on unprecedented projects, the promise of adult stem cells and the ultimate success they will achieve…remind them they are doing so on the tail coats of the innumerable scientists, doctors and patients who have blazed the path before them…and please remind them to apologize to the millions who have died waiting for stem cell treatments in the USA. http://repairstemcell.wordpress.com/why-no-stem-cells-in…/

“Four women have had new vaginas grown in the laboratory and implanted by doctors in the US.

A tissue sample and a biodegradable scaffold were used to grow vaginas in the right size and shape for each woman as well as being a tissue match.

They all reported normal levels of “desire, arousal, lubrication, orgasm, satisfaction” and painless intercourse.

Experts said the study, published in the Lancet, was the latest example of the power of regenerative medicine.”

Stem Cell-based Baldness Cure One Step Closer

http://www.mensfitness.com/sites/mensfitness.com/files/imagecache/node_page_image/article_images/male-pattern-baldness-main_0.jpg

January 28, 2014 – by mburatov

Scientists might be able to offer people with less that optimal amounts of hair new hope when it comes to reversing baldness. Researchers from the University of Pennsylvania say they’ve moved closer to using stem cells to treat thinning hair — at least in mice.

This group said that the use of stem cells to regenerate missing or dying hair follicles is considered a potential way to reverse hair loss. However, the technology did not exist to generate adequate numbers of hair-follicle-generating stem cells.

But new findings indicate that this may now be achievable. “This is the first time anyone has made scalable amounts of epithelial stem cells that are capable of generating the epithelial component of hair follicles,” Dr. Xiaowei Xu, an associate professor of dermatology at Penn’s Perelman School of Medicine, said in a university news release.

According to Xu, those cells have many potential applications that extend to wound healing, cosmetics and hair regeneration.In their new study, Xu’s team converted induced pluripotent stem cells iPSCs – reprogrammed adult stem cells with many of the characteristics of embryonic stem cells – into epithelial stem cells. This is the first time this has been done in either mice or people.

The epithelial stem cells were mixed with certain other cells and implanted into mice. They produced the outermost layers of the skin and hair follicles that are similar to human hair follicles.

This study was published in the Jan. 28 edition of the journal Nature Communications.This suggests that these cells might eventually help regenerate hair in people.

Xu said this achievement with iPSC-derived epithelial stem cells does not mean that a treatment for baldness is around the corner. Hair follicles contain both epithelial cells and a second type of adult cells called dermal papillae.

“When a person loses hair, they lose both types of cells,” Xu said. “We have solved one major problem — the epithelial component of the hair follicle. We need to figure out a way to also make new dermal papillae cells, and no one has figured that part out yet.”

Experts also note that studies conducted in animals often fail when tested in humans.

From http://www.plosbiology.org – January 6, 7:09 AM

Spinal cord injury is an important cause of disability in young adults, and stem cells have been proposed as a possible treatment. Here we systematically assess the evidence in the scientific literature for the effectiveness of stem-cell–based therapies in animal models of spinal cord injury.

Ella Buzhor\’s insight:

The comparison between multiple allogeneic stem cell treatments revealed improved both motor and sensory function in SCI animal models. Differentiation prior to implantation and IV route of cell administration yielded better outcomes.

  • cells were safe and well tolerated
  • one group receiving a 150 million cell dose displaying a 500 percent improvement over the placebo group.

Pluristem stem cell trial to treat muscle injury meets main goal

TEL AVIV Tue Jan 21, 2014 3:07am EST

(Reuters) – Pluristem Therapeutics Inc said results from its early/mid-stage clinical trial indicated its placenta-derived stem cells for the treatment of muscle injury were safe and provided evidence the cells might be effective in treating orthopedic injuries.

\”Patients treated with PLX-PAD had a greater improved change of maximal voluntary muscle contraction force than the placebo group,\” Israel-based Pluristem said in a statement on Tuesday.

The trial was conducted at the Orthopedic Clinic of the Charite University Medical School under the auspices of the Paul-Ehrlich-Institute, Germany\’s health authority.

\”This was a very important study not only for Pluristem but for the cell therapy industry in general,\” Pluristem chief executive Zami Aberman said. \”Based on these results, we intend to move forward with implementing our strategy towards using PLX cells in orthopedic indications and muscle trauma.\”

The injured muscle studied was the gluteus medius muscle in the buttock. Total hip replacement surgery via the standard transgluteal approach necessitates injury of the gluteus medius muscle, and post-operative healing is crucial for joint stability and function.

\”The study showed that PLX-PAD cells were safe and well tolerated,\” the statement said.

The primary efficacy endpoint of the study was the change in maximal voluntary isometric contraction force of the gluteal muscle six months after surgery.

Efficacy was shown in two groups treated with the cells, with one group receiving a 150 million cell dose displaying a 500 percent improvement over the placebo group. Patients treated with a 300 million cell dose showed a 300 percent improvement over the placebo.

An analysis of the gluteal muscle indicated an increase in muscle volume in those patients treated with PLX-PAD cells versus the placebo group.

No mention of the words “stem cell” in the headline.  No mention of stem cells until the 6th paragraph.  Why make it so difficult for patients to find these articles? In any case, we eagerly await the results! -dg

“Stem cells can be morphed into any cell in the body. Patients like Quinn have bone marrow removed and the stem cells inside are then changed in the kind of stem cells found in the brain and spinal cord.

Those cells will then be injected directly into the spinal cord. The hope is that they will repair the insulation and perhaps even the wires underneath.”

FDA-Regulated Study of Cord Blood Stem Cells to Treat Acquired Hearing Loss Launches

Signals Potential of Newborn Stem Cells in Regenerative Medicine for Common Disorders

SAN BRUNO, Calif., Jan. 16, 2014 /PRNewswire-USNewswire/ – Cord Blood Registry® (CBR®), the world’s largest and most experienced newborn stem cell company, announces the start of a U.S. Food and Drug (FDA)-regulated study being conducted at Florida Hospital for Children in Orlando to investigate the use of a child’s stem cells from their own stored umbilical cord blood as a treatment for acquired sensorineural hearing loss.

(Logo: http://photos.prnewswire.com/prnh/20131216/DC33657LOGO-a)

In the United States, approximately 15 percent of children suffer from low or high-frequency hearing loss.[i] The most common type of hearing loss, especially at high frequencies, is sensorineural. Acquired sensorineural hearing loss results from damage to hair cells in the inner ear (cochlea) and can be caused by illness, medication, noise exposure, birth injury, or head trauma. A child’s ability to hear affects the development of language skills, and hearing impairments can lead to poor academic and social development.[ii]

The groundbreaking phase 1 study has a primary objective of determining the safety of using cord blood stem cells in a select pediatric patient population while also assessing whether this approach to treatment improves inner ear function, speech, and language development. Researchers will follow 10 children, ranging in age from 6 weeks to 6 years, who have been diagnosed with acquired hearing loss for less than 18 months and who have their own cord blood unit processed and stored under CBR’s strict quality controls. Children with a known genetic cause of deafness are ineligible for study participation. Patients will receive one intravenous infusion of their own umbilical cord blood stem cells. All patients will return for follow-up at 1 month, 6 months, and 1 year post-treatment.

The trial, supported by CBR, follows promising evidence from preclinical studies suggesting that the infusion of human umbilical cord stem cells may help repair damaged cells in the inner ear in ways that could lead to hearing improvement.[iii]

“As more children survive premature birth, we are observing increasing numbers of very young children with significant acquired hearing loss, and currently there are no therapies available for reversing that damage,” says Linda Baumgartner M.S., CCC-SLP, LSLS cert. AVT, the trial’s Speech and Language Pathologist and hearing loss expert.  James Baumgartner, MD, Surgical Director of Florida Hospital for Children’s Comprehensive Pediatric Epilepsy Center and the study’s principal investigator notes that “presently, the only treatment options for acquired sensorineural hearing loss are hearing aids or cochlear implants, neither of which actually repairs the damage. Using cord blood stem cells to help trigger the body’s own repair mechanisms could provide a non-invasive therapeutic option that does not exist today.”

During the last 25 years, cord blood stem cells have been used in more than 30,000 transplants performed worldwide for the treatment of nearly 80 serious diseases and disorders in both adults and children. The evolution of stem cell therapies has paved the way for further research being conducted through FDA-regulated clinical trials to uncover their potential in regenerative medicine applications.

“Cord Blood Registry continues to lead the industry in evaluating the potential of newborn stem cells in neurological damage, supporting FDA-regulated clinical trials in autism, cerebral palsy, pediatric stroke, traumatic brain injury, and now hearing loss,” underscores Heather Brown, Vice President of Scientific & Medical Affairs at CBR. “We are excited to learn from the outcomes of this particular study and from future studies that may evaluate broader populations affected by hearing loss or other neurological impairments for which there are limited treatment options today,” adds Brown.

Belgian scientists repair bones with new stem cell technique – CBS News

In ALL ARTICLES, SCIENCE & STEM CELLS, STEM CELLS IN THE NEWS, VICTORIES & SUCCESS STORIES on January 16, 2014 at 12:49 pm

BRUSSELS  – Belgian medical researchers have succeeded in repairing bones using stem cells from fatty tissue, with a new technique they believe could become a benchmark for treating a range of bone disorders.

The team at the Saint Luc university clinic hospital in Brussels have treated 11 patients, eight of them children, with fractures or bone defects that their bodies could not repair, and a spin-off is seeking investors to commercialize the discovery.

Doctors have for years harvested stem cells from bone marrow at the top of the pelvis and injected them back into the body to repair bone.

The ground-breaking technique of Saint Luc’s centre for tissue and cellular therapy is to remove a sugar cube sized piece of fatty tissue from the patient, a less invasive process than pushing a needle into the pelvis and with a stem cell concentration they say is some 500 times higher.

The stem cells are then isolated and used to grow bone in the laboratory. Unlike some technologies, they are also not attached to a solid and separate ‘scaffold’.

“Normally you transplant only cells and you cross your fingers that it functions,” the centre’s coordinator Denis Dufrane told Reuters television.

His work has been published in Biomaterials journal and was presented at an annual meeting of the International Federation for Adipose Therapeutics and Science (IFATS) in New York in November.

Bone Formation

“It is complete bone tissue that we recreate in the bottle and therefore when we do transplants in a bone defect or a bone hole…you have a higher chance of bone formation.”

The new material in a lab dish resembles more plasticine than bone, but can be molded to fill a fracture, rather like a dentist’s filling in a tooth, hardening in the body.

Some of those treated have included people recovering from tumors that had to be removed from bones. One 13-year-old boy, with a fracture and disorder that rendered him unable to repair bone, could resume sports within 14 months of treatment.

“Our hope is to propose this technology directly in emergency rooms to reconstitute bones when you have a trauma or something like that,” Dufrane said.

A spin-off founded last year called Novadip Biosciences will seek to commercialize the treatment, initially to allow spinal fusion among elderly people with degenerated discs.

It may also seek to create a bank of bone tissue from donors rather than the patients themselves.

IFATS president Marco Helder, based at Amsterdam’s VU university medical centre, said the novelty was the lack of solid scaffold.

“It is interesting and it is new, but it will have limitations regarding load-bearing capacity and, as with other implants, it will need to connect to the blood vessels of the body rapidly to avoid dying off,” he said, adding:

“Any foreign object can cause irritation and problems, so the fact that this is just host tissue would be an advantage.”

Stem Cell Scarring Aids Recovery from Spinal Cord Injury

Oct. 31, 2013 — In a new study, researchers at Karolinska Institutet in Sweden show that the scar tissue formed by stem cells after a spinal cord injury does not impair recovery; in fact, stem cell scarring confines the damage. The findings, which are published in the scientific journal Science, indicate that scar tissue prevents the lesion from expanding and helps injured nerve cells survive…

Stem Cells Improve Cognition After Brain Injury

Research led by Charles Cox at the University of Texas Health Science Center has shown that stem cell therapy given during the critical time window after traumatic brain injury promotes lasting cognitive improvement. These experiments, which were published in the latest issue of the journal Stem Cells Translational Medicine, provide a pre-clinical model for experiments with larger animals.

After the brain has suffered a traumatic injury, there are few treatment options. Damage to the brain can be severe, and can also cause ongoing neurological impairment. Approximately half of all patients with severe head injuries need surgery to remove or repair ruptured blood vessels or bruised brain tissue.

In this work from Cox’s lab, stem cells from bone marrow known as multipotent adult progenitor cells (MAPCs) were used. MAPCs seem to be a subpopulation of mesenchymal stem cells, and they have a documented ability to reduce inflammation in mice immediately after traumatic brain injury. Unfortunately, no one has measured the ability of MAPCs to improve the condition of the brain over time.

Cox, Distinguished Professor of Pediatric Surgery at the UTHealth Medical School and in collaboration with the Children’s Fund, Inc., injected two groups of brain-injured mice with MAPCs two hours after injury and then once again 24 hours later. One group received a dose of 2 million cells per kilogram and the other a dose five times greater.

After four months, those mice that had received the stronger dose not only continued to have less inflammation, but they also showed significant gains in cognitive function. Laboratory examination of the brains of these rodents confirmed that those that had received the higher dose of MAPCs had better brain function than those that had received the lower dose.

According to Cox, “Based on our data, we saw improved spatial learning, improved motor deficits and fewer active antibodies in the mice that were given the stronger concentration of MAPCs.” Cox also indicated that this study indicates that intravenous injection of MAPCs might very well become a viable treatment for people with traumatic brain injury in the future.
