SanBio Announces Enrollment of First Cohort of Patients in Its Clinical Trial of Stem Cell Therapy for Chronic Stroke

A special dog used to help people is getting some much-needed help of her own at a Virginia clinic, myFOXdc.com reported.

Red, a 12-year-old black Labrador, is one of the last surviving search and rescue dogs deployed during the 9/11 attacks.

Her handler, Heather Roche, told WTTG-TV that Red was recently certified when Sept. 11, 2001, occurred, and the devastating terror attacks were her first big mission.

Red's job was to find DNA evidence at The Pentagon's north parking lot with 26 other dogs, and according to Roche, she did a "fantastic job."

"I got her as a puppy ... You have to convince [her] everything that she does, whether it's climbing ladders or any kind of search, that it's her idea," Roche told WTTG-TV. "No matter what I've asked her to do, she's done it and she's done it flawlessly."

But in her old age Red developed crippling arthritis, and underwent stem cell regenerative therapy Monday to help ease her pain so she can get back out on the job.

Dr. John Herrity of Burke Animal Clinic in Burke, Va., told WTTG-TV, "Red has a back issue that, after a fall from a ladder has not really been right, and has been living in pain, so we're going to give those stem cells IV [intravenously] and then also inject them along the back to try to help Red's comfort."

"She's had a great career and has made a difference to a lot of families by bringing their loved ones home," Roche said.

Vitro Biopharma Receives Approval for Presentation to the International Society for Cellular Therapy

NEW YORK, March 20, 2012 (GLOBE NEWSWIRE) -- NeoStem, Inc. (NYSE Amex:NBS) ("NeoStem" or "the Company") is a leader in the cell therapy industry, developing cell based therapeutics supported by the Company's expertise in contract manufacturing. This strategic combination and depth of experience in cell therapy development and manufacturing provide NeoStem with unique capabilities to develop its own cell therapies and that sets the Company apart from others in the cell therapy landscape. 2011 represented a major year of strategic transition for NeoStem, and the Company plans to build upon that in 2012 and in the years ahead.

NeoStem reported its audited results for 2011. Consolidated revenues for the year ended December 31, 2011 were $73.7 million compared to $69.8 million for 2010. The Company's consolidated net loss for 2011 was $56.6 million, which included $10.3 million of non-cash equity-based compensation expense, $19.4 million of goodwill impairment charges and $9.0 million of depreciation and amortization. Overall, the Company's consolidated cash loss for 2011 was $15.5 million (see reconciliation below). Net loss attributable to NeoStem common shareholder interests for 2011 was $47.8 million, or $0.54 per share.

As of December 31, 2011, the Company had consolidated cash and cash equivalents of $12.7 million, and an additional $2.5 million in cash held in escrow (classified in Other Assets).

NeoStem believes that the opportunities that exist today in cell therapy are robust and growing despite a persistently difficult financial environment, making this an opportunistic time to pursue the monetization of the Company's 51% ownership of Suzhou Erye Pharmaceutical Co., Ltd. and bolster its cell therapy business. In June 2011, the Company engaged a financial advisor to lead the effort to pursue the possible divestiture of the Company's interest in Erye. Marketing efforts are underway and have generated interest from both financial and strategic buyers.

On the therapeutics side of the business NeoStem now has a pipeline of assets that includes Amorcyte (Phase 2 trial for preservation of heart function after a heart attack), Athelos (physician sponsored Phase 1 trials for a range of auto-immune conditions) and pre-clinical development work on its VSEL(TM) technology. The Company's most advanced asset is AMR-001 for the treatment of acute myocardial infarction for which enrollment for a Phase 2 study in the United States commenced in January. The study is a multicenter, randomized, double-blind, placebo-controlled clinical trial to evaluate the safety and efficacy of infarct-related artery infusion of AMR-001, an autologous bone marrow derived cell therapy enriched for CD34+ cells. AMR-001 is administered 5 to 11 days post-stent placement in patients diagnosed with an ST segment elevation myocardial infarction ("STEMI") with ejection fraction less than or equal to 48%. The study will include 160 subjects, age 18 and older, randomized 1:1 between treatment and control. The manufacturing, product supply, and logistics for the trial will be supported by Progenitor Cell Therapy, LLC, NeoStem's contract manufacturing company.

Amorcyte currently has ten activated clinical trial sites for its Phase 2 AMI clinical trial with the initial patients enrolled. Trial enrollment is expected to be completed in approximately one year with data read out six months following the last treated patient. The Amorcyte franchise is supported by a strong patent portfolio which includes both composition of matter and methods of treatment around use of these hematopoietic stem cells for treatment of cardiac ischemia and other ischemic tissue that result from vascular insufficiency. The Company sees Amorcyte as a pipeline of therapeutics with potential in multiple indications from STEMI to congestive heart failure and other related vascular insufficiencies. The Amorcyte product addresses both an unmet medical need and a large potential market.

"One of the most important attributes of AMR-001 is that it's 'natural.' We are enhancing the body's normal and natural response to ischemic injury," said Dr. Robin Smith, CEO of NeoStem. "Ample historical evidence, published literature and our own compelling Phase 1 data give us confidence that this product will ultimately make it to the marketplace. Our next most advanced asset is held by Athelos Corporation, (a NeoStem company, partnered with Becton, Dickinson and Company) which is developing a novel T-cell platform for immunological disorders. The Athelos T-cell technology represents an innovative approach to restoring immune balance with potential applications in graft vs. host disease (GvHD), solid organ transplant (SOT) and autoimmune diseases, such as asthma and diabetes. Multiple physician sponsored phase 1 studies are expected to report results that will be used to determine the direction of clinical development.

"NeoStem is also developing pre-clinical assets, including its VSEL(TM) Technology platform for regenerative medicine, which NeoStem believes is an endogenous pluripotent non-embryonic cell that has the potential to change the paradigm of cell therapy as we know it today. These activities have received awards in excess of $2.5 million which funds support the work of prestigious researchers who are pioneering this science with NeoStem.

"Behind the development of these therapeutic assets is the NeoStem cell therapy contract manufacturing business (PCT) which itself continues to grow. New clients have engaged PCT to assist them in the development of their products, including a global, diversified healthcare company who recently selected PCT to provide stem cell processing in our two GMP manufacturing facilities in the United States (California and New Jersey). PCT's prominence in the marketplace continues to grow and that is reflected by both client satisfaction and the revenues the company generates.

"As we look to the year ahead, we are excited on multiple fronts. Our capital preservation efforts are now bearing fruit as our cash burn rate is in-line with our peers. We expect to continue to carefully invest our capital in projects that meet our internal rate of return hurdle and risk parameters. We believe the PCT and Amorcyte acquisitions have created true value for our shareholders and we look forward to demonstrating that as these assets reach their respective value inflection points. We see the unmet medical need in cardiology and the treatment burden associated with chronic diseases as representing a significant challenge to modern society. We believe that cell therapy holds many of the solutions to the health crisis that societies face and have the potential to create real pharmacoeconomic benefit as well as shareholder value for our company.

Stem Cell Therapy Helping Heroic Dogs Recover

News4's Darcy Spencer explains how a breakthrough treatment is helping search and rescue dogs like Red recover after years of working in disaster zones.

A breakthrough treatment is helping area search-and-rescue dogs that played key roles on Sept. 11, 2001, and during other disasters.

Red's first assignment as a search, rescue and recovery dog was at the Pentagon following the 9/11 attacks. Years of rescue work and a 12-foot fall from a ladder have taken a toll. Arthritis forced Red into retirement in July and turned her into a couch potato.

The 12-year-old black lab received a breakthrough stem cell treatment today that will ease her pain and give her more mobility.

Her veterinarian, Dr. John Herrity, of the Burke Animal Clinic, has done more than two dozen of the stem cell operations developed by Medivet America, which also donated the cost of the procedure.

The treatment won't bring Red back out of retirement, but it is expected to put spring back in her step within a couple of months.

Two other 9/11 search-and-rescued dogs have been treated with stem cell therapy and are back to their normal activities.

However, according to a study published March 15 in the journal Cell Stem Cell, a special type of brain cell created from stem cells could help restore the muscle coordination deficits that are responsible for uncontrollable spasms, a characteristic of the disease. The researchers demonstrated that movement in mice with a Huntington's-like condition could be restored.

Su-Chun Zhang, a University of Wisconsin-Madison neuroscientist and the senior author of the study, said:

In the study Zhang, who is an expert in creating various types of brain cells from human embryonic or induce pluripotent stem cells, and his team focused on GABA neurons. The degradation of GABA cells causes the breakdown of a vital neural circuit and loss of motor function in individuals suffering from Huntington's disease.

According to Zhang, GABA neurons generate a vital neurotransmitter, a chemical that helps support the communication network in the brain that coordinates movement.

Zhang and his team at the UW-Madison Waisman Center, discovered how to generate large quantities of GABA neurons from human embryonic stem cells. The team's goal was to determine whether these cells would safely integrate into the brain of a mouse model of Huntington's disease.

LOS ANGELES--(BUSINESS WIRE)--

Moraga Biotechnology Corporation, an adult stem cell company based in Culver City, California, announces the publication of its blood-derived Blastomere-Like Stem Cells (BLSCs) patent with the European Patent Office (EPO). The EPO had previously granted the patent of the Companys non-embryonic totipotent blastomere-like stem cell on May 19, 2011 in which the English claims were erroneously limited to rat stem cells. This error was corrected in the republished EP17895540B9. The EP17895540B9 claims isolated mammal/human post-natal blastomere-like stem cells and isolation methods.

Moragas chief executive, Dr. John F. Wong, noted: We are very pleased to have the EPO grant the 540 patent as Moraga and its U.K. partner, Pharmacells, Ltd. achieved a major milestone validating its adult stem cell technology. Moraga is particularly indebted to its patent counsel, Fish and Associates (Irvine, CA) for its fine work in prosecuting its patents both in Europe and currently in the United States with the U.S. Patent and Trade Office (USPTO).

Moraga Announces Issuance of Adult Stem Cell Patent for Humans

CLEVELAND, Ohio -- Talk about a potentially major game changer for a woman and her eggs.

For the first time ever, researchers have proven the existence of egg-producing stem cells in the ovaries of humans.

The breakthrough throws open the door -- albeit years down the road -- to the possibility that women in their 30s and 40s, whose fertility is on the decline, could replenish their dwindling egg supplies.

Researchers at Massachusetts General Hospital in Boston used a new technique to pull stem cells from the ovaries of six women in their 20s and 30s whose ovaries had been removed as part of gender reassignment surgery.

When grown in the lab, those stem cells produced oocytes, which are immature egg cells that have not yet developed into an egg.

A video on the journal's web site does a good job of describing the research in layman's terms.

"These cells, when maintained outside the body, are more than happy to make eggs on their own," Jonathan Tilly, a professor of obstetrics, gynecology and reproductive biology at Harvard Medical School and chief of research at the Massachusetts General Hospital Vincent Department of Obstetrics and Gynecology, said in a video interview.

"And if we can guide the process correctly, I think it opens up the chance that sometime in the future we might get to the point of having an unlimited source of human eggs. . . . It would rewrite, essentially, human assisted reproduction," he said.

The findings of the research team led by Tilly are in the March issue of the journal Nature Medicine.

Fertility specialists view these findings not only as exciting but also as a complete paradigm shift. And rightly so, since conventional wisdom has long dictated that a woman is born with all of the eggs she'll ever have. And when they're gone, they're gone.

Stem cells might one day form human eggs, research finds

Mixing the stem cells of an organ recipient with those of the donor could help to keep the body's picky immune system from rejecting transplants.

kalewa/Shutterstock

One of the greatest challenges in medicine is the need for replacement organs. Every 10 minutes another person's name is added to the national organ transplantation waiting list, the length of which now exceeds 100,000. Eighteen of these people die each day. Those who are fortunate enough to receive an organ often have to take immunosuppressive drugs for the rest of their lives, thus making them more vulnerable to other infections, and even then their new organs may gradually be rejected by their immune system.

One potential way to overcome this problem is through the creation of a chimeric immune system by mixing the immune (hematopoetic) stem cells of the recipient with that of the donor. As explained in last week's issue of Science Translational Medicine:

According to Greek mythology, the Chimera was a fire-breathing creature made of parts from different animals: the body of a lioness, a snake's head at the end of the tail, and the head of the goat. Sightings of this fearsome beast portended any of a number of terrible disasters. In the context of organ transplantation, a "chimera" can indicate both desirable and disastrous outcomes. For example, hematopoietic chimerism, in which the immune cells in the graft recipient come from both the host and the donor, may promote graft tolerance, but may also cause graft-versus-host disease (GVHD), in which the donor immune cells attack the healthy tissue of the host.

The underlying problem behind rejection and GVHD -- both of which shrink the potential donor pool -- is matching. Now, a novel procedure has come one step closer to overcoming the matching problem and achieving transplantation tolerance. In an exciting, albeit small, study the University of Louisville team transplanted mismatched, unrelated donor kidneys into eight patients along with a mix of donor hematopoetic stem cells and a special population of tolerance-inducing facilitator cells (FCs). These FCs have been shown in animal models to improve engraftment (acceptance of the graft) and avoid GVHD. The results and potential meaning are well-summarized by Science Translational Medicine:

Five of eight kidney transplant recipients exhibited durable chimerism and were weaned off immunosuppressive therapies by one year after transplantation, with no signs of GVHD or engraftment syndrome. If confirmed in larger patient cohorts, this approach to transplantation could free some patients from the difficulties associated with lifelong immunosuppression and add transplantation as a viable option for patients for whom no matched donors exist.

An editorial written in STM about the study says that this procedure "may potentially have an enormous, paradigm-shifting impact on solid-organ transplantation" and that "few transplant developments in the past half-century have been more enticing than these that put transplantation tolerance within our grasp." This editor followed up with the primary investigator of the study, Dr. Suzanne Ildstad from the Institute for Cellular Therapeutics at the University of Louisville, to ask about the future of the procedure as well as other applications that are being explored:

Your paper refers to applications "not only in sold organ and cell transplant recipients but also for ... hemoglobinopathies, inherited metabolic disorders, and autoimmune diseases." What other applications are currently being explored using this novel chimeric approach?

We are currently working on applying this procedure to sickle cell disease, thalassemia, metachromatic leukodystrophy, and in the near future, type 1 diabetes.

A Chimeric Immune System: Fixing the Problem With Organ Transplant

This photo taken Thursday, March 8, 2012, Lindsay Porter is seen in her home in Chicago. Lindsay Porter's kidneys were failing rapidly when a friend offered to donate one of his. Then she made an unusual request: Would he donate part of his immune system, too? (AP Photo/M. Spencer Green)

WASHINGTON Lindsay Porter's kidneys were failing rapidly when a friend offered to donate one of his. Then she made an unusual request: Would he donate part of his immune system, too?

Every day for the rest of their lives, transplant recipients must swallow handfuls of pills to keep their bodies from rejecting a donated organ. The Chicago woman hoped to avoid those problematic drugs, enrolling in a study to try to trick her own immune system into accepting a foreign kidney.

It's one of a series of small, high-stakes experiments around the country that has researchers hopeful that they're finally closing in on how to help at least some transplant patients go drug-free. The key: Create a sort of twin immunity, by transplanting some of the kidney donor's immune-producing cells along with the new organ.

"I'm so lucky," says the 47-year-old Porter, who stumbled across the research at Chicago's Northwestern University. Porter was able to quit her pills last summer, a year after her transplant, and says, "I feel amazing."

These experiments are a big gamble. If the technique fails, patients could lose their new kidney, possibly their lives. Doctors stress that no one should try quitting anti-rejection drugs on their own.

Why risk it even in a careful scientific study? Anti-rejection medications can cause debilitating, even deadly, side effects, from fatigue and infections to an increased risk of cancer and kidney damage.

Without the drugs, "the hope for me is I'm able to keep this kidney for the rest of my life," Porter says.

Across the country, Stanford University is testing a slightly different transplant method and hosted a reunion earlier this month for about a dozen kidney recipients who've been drug-free for up to three years.

"These people who are off their drugs, they're cured," says Dr. Samuel Strober, who leads the study of Stanford's approach. "If they have to be on drugs the rest of their life, it doesn't have the same meaning of `cure.'"

CHICAGO --- A genetic pathway previously known for its role in embryonic development and cancer has been identified as a target for systemic sclerosis, or scleroderma, therapy. The finding, discovered by a cross-disciplinary team led by John Varga, MD, John and Nancy Hughes Distinguished Professor of Rheumatology at Northwestern University Feinberg School of Medicine, was recently published in the journal Arthritis & Rheumatism.

"We showed, for the first time, that the Wnt signaling pathway is abnormally activated in scleroderma patients," said Varga, who is also a physician at Northwestern Memorial Hospital. "This is significant for three reasons. First, it gives a better picture of scleroderma and fibrosis in general. Second, it provides a strategy for assessing disease severity, progression, and activity. And third, it opens a door for the design of treatments that aim to block the Wnt pathway and restore its normal controlled activity."

Varga's laboratory collaborated with a pulmonary team at Northwestern, along with teams at Case Western Reserve University and Dartmouth University on the discovery.

Researchers studied skin and lung biopsies from scleroderma patients and found that the Wnt pathway was 'turned on', in contrast to healthy individuals where the pathway was 'turned off.' Varga said this activation may be due to loss of Wnt inhibitors that normally serve as 'brakes' on the pathway to prevent its activation.

The team also examined what the pathway does using fibroblasts and stem cells from healthy people. They found Wnt causes fibroblast activation and blocks the development of fat cells (adipocytes), which directly contribute to scar formation and tissue damage seen in scleroderma.

Scleroderma is a chronic autoimmune disease in which the body's immune system attacks itself. It causes progressive thickening and tightening (fibrosis) of the skin and also can lead to serious internal organ damage and, in some cases, death. Scleroderma affects an estimated 150,000 people in the United States, most frequently young to middle-aged women.

"Scleroderma is a complex and poorly understood disease with no cure," said Varga. "Our findings suggest that treatments targeting the Wnt signaling pathway could lead to an effective treatment."

Varga said Northwestern researchers next plan to conduct multi-center preclinical studies to evaluate treatments that block the Wnt pathway in animal models and measure Wnt activity in additional scleroderma biopsies to see if it can be clinically useful as a biomarker.

Bioplasty - Stem Cell Treatments

Dr. Konstantine K. Yankopolus

The state Department of Health restricted a second doctor's license for working under the direction of Dr. Zannos Grekos in performing a stem cell treatment and for falsifying a medical report after a patient died, according to the state order.

The emergency license restriction is against Dr. Konstantine K. Yankopolus, 3880 Colonial Blvd., Suite 2, Fort Myers, according to the order issued by the state health department late Monday.

The restriction only prohibits Yankopolus from doing anything with stem cells. After a career as an obstetrician/gynecologist, he is now in general practice.

"We attempted a life-saving procedure on a very sick patient and it didn't go well," Yankopolus said Monday night. "Our motivation was pure the patient had no other option."

The state's action comes on the heels of Grekos attorney last week issuing a statement that another doctor, and not his client, was involved in the treatment of a 77-year-old Indiana man who died March 2. Grekos attorney also denied that a stem cell treatment was performed, only liposuction.

The state health department suspended Grekos license after the death, saying Grekos violated an earlier restriction that he not to do anything with stem cells or bone marrow aspirate in his practice at 9500 Bonita Beach Road, Suite 310.

Lee County sheriff's authorities identified the man as Richard Poling, of Newburgh, Ind. The Sheriff's Office also is conducting a criminal probe.

Grekos has been under state scrutiny by state health regulators for well over a year when an earlier patient, a 66-year-old breast cancer patient, went to him for stem cell treatment in 2010 for neurological problems. She later fell, suffered severe brain damage and was taken off life support. After her death, the state ordered Grekos not to do anything with stem cells or bone marrow aspirate in his practice.

The restriction did not prohibit him from conducting educational seminars in the community about stem cell therapy or from arranging for patients to go for the treatment in the Dominican Republic.

The degradation of GABA cells causes the breakdown of a vital neural circuit and loss of motor function in individuals suffering from Huntington's disease.

According to Zhang, GABA neurons generate a vital neurotransmitter, a chemical that helps support the communication network in the brain that coordinates movement.

Zhang and his team at the UW-Madison Waisman Center, discovered how to generate large quantities of GABA neurons from human embryonic stem cells. The team's goal was to determine whether these cells would safely integrate into the brain of a mouse model of Huntington's disease.

Stem Cell Therapy Helping Heroic Dogs Recover

News4's Darcy Spencer explains how a breakthrough treatment is helping search and rescue dogs like Red recover after years of working in disaster zones.

A breakthrough treatment is helping area search-and-rescue dogs that played key roles on Sept. 11, 2001, and during other disasters.

Red's first assignment as a search, rescue and recovery dog was at the Pentagon following the 9/11 attacks. Years of rescue work and a 12-foot fall from a ladder have taken a toll. Arthritis forced Red into retirement in July and turned her into a couch potato.

The 12-year-old black lab received a breakthrough stem cell treatment today that will ease her pain and give her more mobility.

Her veterinarian, Dr. John Herrity, of the Burke Animal Clinic, has done more than two dozen of the stem cell operations developed by Medivet America, which also donated the cost of the procedure.

The treatment won't bring Red back out of retirement, but it is expected to put spring back in her step within a couple of months.

Two other 9/11 search-and-rescued dogs have been treated with stem cell therapy and are back to their normal activities.

Hero Dog Receives Stem Cell Therapy

London, March 19 (ANI): An injection of human embryonic stem cells (hESCs) into their brain helped monkeys with Parkinson's disease-like symptoms ease their suffering, say Japanese scientists.

These cells were injected into monkeys whose brains had been damaged by a chemical that destroys dopamine-producing neurons and so causes Parkinson's symptoms.

In the study conducted by Jun Takahashi of Kyoto University in Japan and colleagues, two monkeys received hESCs that had been matured into an early form of neural cell.

Six months later, the monkeys had recovered 20 to 45 per cent of the movement they had lost before treatment.

Post-mortems a year after treatment showed that the cells had developed into fully functioning dopamine-secreting neurons.

Another monkey that received less-mature neural cells also showed improvements.

"Monkeys starting with tremors and rigidity [began] to move smoothly, and animals originally confined to sitting down were able to walk around," New Scientists quoted Takahashi as saying.

But it will probably be four to six years before clinical trials in humans begin, according to the team. (ANI)

Human stem cell injections ease Parkinson's symptoms in monkeys

Among the primary causes of adult-onset blindness are degenerative diseases of the retina, such as macular degeneration and retinitis pigmentosa. While some treatments have been developed that slow down the rate of degeneration, the clinical situation is still generally unsatisfactory. But if you could grow a new retina, transplant might be a possible cure. Now new hope is springing up from a research project at the University of Wisconsin-Madison in which scientists have succeeded in growing human retinal tissue from stem cells.

Pluripotent stem cells are capable of forming nearly any tissue in the body including retinal tissue. There has been great controversy about using pluripotent stem cells for human research or treatment, as historically the only source was to harvest them from early stage human embryos. Instead, for this work the researchers were able to regress mature body cells back into the pluripotent stem cells from which they originally grew. The process is called reprogramming, and is accomplished by inserting a set of proteins into the cell.

To produce the pluripotent stem cells, a white blood cell was taken from a simple blood sample. Genes which code for the reprogramming proteins are inserted into a plasmid, a nonliving ring of DNA. The cell is then infected with the plasmid, rather as a virus infects a cell, with the difference that the plasmid's genes do not become part of the cell's genetic structure. As the reprogramming proteins are formed within the cell by the plasmid DNA, the cell has a good chance of being reprogrammed into a pluripotent stem cell. This stem cell can then be encouraged to grow and differentiate into retinal tissue rather than make more blood cells.

Laboratory-grown human retinal tissue will certainly be used in testing drugs and to study degenerative diseases of the retina, and may eventually make available a new transplantable retina, or a new retina that is grown in place within the eye.

The figure above compares a schematic of the human retina with a photomicrograph of laboratory-grown retinal tissue. The new tissue has separated into at least three layers of cells, with rudimentary photosensitive rods or cones (red) at the top of the picture, and nerve ganglia (blue-green) at the bottom. The blue cells in the middle layer are likely bipolar retinal cells. The structure of the lab-grown retinal tissue is similar to that of a normal human eye, as can be seen by comparison with the retina schematic. The cells also formed synapses, which provide the channels through which optical information flows to the brain.

"We don't know how far this technology will take us, but the fact that we are able to grow a rudimentary retina structure from a patient's blood cells is encouraging, not only because it confirms our earlier work using human skin cells, but also because blood as a starting source is convenient to obtain," says Dr. David Gamm, pediatric ophthalmologist and senior author of the study. "This is a solid step forward." Further steps are eagerly awaited by those living in the dark.
