International Stem Cell Corporation (OTCBB:ISCO), http://www.internationalstemcell.com, and Sankara Nethralaya, http://www.sankaranethralaya.org, announced today commencement of a collaboration to develop ISCO's 'CytoCor™' stem cell-derived corneal tissue. The goal is to use CytoCor to treat corneal blindness and vision impairment. 'This is one more step in ISCO's stated plan of building its portfolio of therapeutic agents through strategic alliances throughout the world,' said Chairman, Ken Aldrich.

CytoCor consists of transparent human tissue derived from pluripotent human stem cells. These structures are produced in the laboratory and recent testing at Sankara Nethralaya and laboratories in the US has demonstrated a range of structural, biochemical and refractory properties characteristic of human cornea.

CytoCor may offer a first-in-class opportunity for high-quality, cost-efficient transplantation tissue for the 10 million people world-wide suffering from corneal vision impairment, particularly in India and the rest of Asia, as well as in Europe. Standardized tissues derived from pluripotent stem cells, such as the CytoCor tissue, could eliminate the current problem that corneal tissue derived from donors may harbor diseases that could be transferred from the donor to the recipient. It may also provide a much needed alternative to the use of live and extracted animal eyes in the $500+million market for safety testing of drugs, chemicals and consumer products.

According to Professor Dr. S. Krishnakumar, 'Sankara Nethralaya is dedicated to the development and application of new state-of-the-art ophthalmic technologies. The need for high-volume, high-quality human corneal tissue is substantial, not only in India but across Asia and much of Europe. We appreciate the opportunity to join ISCO in their pursuit to create a new standard of care for the treatment of human corneal disease.' Initially, Dr. Krishnakumar and his team will be using the CytoCor tissue in preclinical studies to explore the ability of the tissue to withstand sutures and bio-compatible glues in order to validate the potential of the tissue for use in animal or human clinical trials.

According to Dr. Geetha Krishnan Iyer, who is involved in the management of ocular surface disease at Sankara Nethralaya, 'The team at Sankara Nethralaya is pleased to collaborate with ISCO on stem cell-derived corneal tissue. In vitro studies to evaluate safety and efficacy of the tissue, as well as surgical feasibility tests will be carried out, following which there could be clinical application in lamellar keratoplasty using the above mentioned tissue. With improvements in surgical techniques over the past few years, the indications for anterior lamellar keratoplasty have expanded significantly. With high demand for donor corneal tissue for the same but limited availability, there is definitely scope for utilizing ISCO's corneal tissue following relevant tests.'

Jeffrey Janus, Senior VP of Operations at ISCO, states: 'This collaboration with the excellent team of scientists and clinicians at Sankara Nethralaya has already proven to be productive. Sankara's ophthalmology expertise and ISCO's cell culture capabilities constitute a perfect match to perfect and advance CytoCor tissue towards future use in treating corneal disease and injuries.'

Melanoma-initiating cells identified by study by Krista Conger, News release, Stanford School of Medicine, June 30, 2010. Excerpt:

Scientists at the School of Medicine have identified a cancer-initiating cell in human melanomas. The finding is significant because the existence of such a cell in the aggressive skin cancer has been a source of debate. It may also explain why current immunotherapies are largely unsuccessful in preventing disease recurrence in human patients.

The news release is about this publication: Human melanoma-initiating cells express neural crest nerve growth factor receptor CD271 by Alexander D Boiko and 11 co-authors, including Irving L. Weissman, Nature 2010(Jul 1); 466(7302): 133-7. [FriendFeed entry].

A blog post about this same publication is: Stanford scientists identify a melanoma-initiating cell by Krista Conger, Scope blog, Stanford School of Medicine, June 20, 2010.

See also a commentary about the publication: Cancer stem cells: Invitation to a second round by Peter Dirks, Nature 2010(Jul 1); 466(7302): 40-1. Excerpt:

Boiko et al. study a type of human skin cancer called melanoma and, in particular, cancer cells enriched in a stem-cell marker called CD271. They find that, unlike other cells from the same tumour, CD271-expressing (CD271+) cells could initiate and maintain tumour growth in vivo — an observation consistent with the existence of a melanoma-cell functional hierarchy.

This finding reflects a view different from that of an earlier study by Quintana et al.[3], which demonstrated that, in some cases, as many as 50% of human melanoma cells have tumorigenic potential. In addition, no marker tested identified a tumorigenic subpopulation. The authors[3] concluded that the frequency of cancer cells that can initiate tumorigenesis depends, in part, on the assessment techniques and assays.

Another news item, based on the same publication, is: New hope in fight against skin cancer as deadly 'master cells' are identified for first time, Mail Online, July 1, 2010. Excerpt:

However Dr Alexander Boiko, who made the discovery at Stanford University, said the newly discovered 'stem cells' in advanced skin cancers were often missed by conventional immunotherapy.

'Without wiping out the cells at the root of the cancer, the treatment will fail,' he said.

Comments: Boiko et al. and Dirks suggest reasons why results different from those of Quintana et al. were obtained. One possibility is that the melanomas that the latter authors studied were at an advanced stage. If, as a cancer progresses, more cells acquire the attributes of cancer stem cells, then advanced melanomas may contain very high frequencies of tumorigenic cells.

As Boiko et al. point out in their publication, "The most crucial test of the tumour stem cell hypothesis is that markers or pathways restricted to tumour stem cells can be targets for curative therapies in the patient, which has not yet been done."

Q&A with ISCO



International Stem Cell Corp. (OTCBB: ISCO) has also been the target of rumor campaigns. ISCO, incidentally, recently announced further positive IP news. Specifically, Advanced Cell Technology, Inc. (ACT) was just issued U.S. Patent Number 7736896 covering a method for producing retinal pigment epithelial cells. ISCO, however, had previously acquired rights to this technology from ACT, so the award solidifies their position in stem cell eye therapies.

ISCO's corneal research also got an unexpected boost last week, though it's not clear how many people know it yet. A stem cell breakthrough from Italy made quite a few headlines. The article that provoked the coverage was in the June 23 online version of The New England Journal of Medicine (NEJM). Specifically, it featured clinical research from professor Graziella Pellegrini et al. titled "Limbal Stem-Cell Therapy and Long-Term Corneal Regeneration." A helpful video by ABC News can be viewed here.



The coverage of the journal article is, however, incomplete. So let me put it in perspective.

The procedure made use of the well-established practice of extracting and cultivating limbal stem cells. Each of the patients, in effect, had stem cells removed from at least one eye. Once the adult stem cells were multiplied in the lab, they were applied to the cornea. There, they regenerated the corneal epithelium (the outermost thin layer of the cornea), restoring sight.

This is wonderful proof of the power of stem cells, but it doesn't represent a breakthrough in terms of basic science or investment possibilities. This is because the cost of extracting these surviving stem cells is very high. So is multiplying and reattaching them. The only reason the experiments were even allowed to proceed is that all the cell materials come from the subjects of the procedures. They would not have been allowed if, for example, scientists wanted to use the stem cells from one patient to treat another patient. Nor is it clear to what extent, if any, a company can patent these procedures.

On the other hand, the Italian procedures were most successful when they were combined with the implantation of replacement corneal structures. Those replacement corneas cannot be regenerated from limbal stem cells. In fact, they came from cadavers.

ISCO, however, is now able to grow them in the lab to produce cheaper, safer corneas. ISCO is involved in discussions with various companies to commercialize those parthenogenic corneal structures.

For most patients, who have enough of their own stem cells to regenerate the corneal epithelium, ISCO's corneas are all that are required to recover sight. Eventually, in fact, I suspect that ISCO will also have off-the-shelf limbal stem cells that will regenerate the corneal epithelial too. These cells would be from each of ISCO's cell bank lines. Now being established, it will include 50-100 cell lines that immune match most of the world's population. No other company has this ability to provide inexpensive stem cells for the masses.

Now allow me to debunk some of the rumors currently being spread about ISCO. Normally, as you know, I don't like to dignify these attacks, but I do make exceptions when it's important. I'm doing this, by the way, in a question-and-answer format that board chairman Ken Aldrich was kind enough to answer. The questions deal with some of the unfounded rumors circulating. If these don't concern you, feel free to skip them. Q1. Did ISCO close its financing?



A1. Yes, they did a $10 million financing, and then used $2.5 million as part of a balance sheet cleanup that removed approximately $15 million of 10% preferred stock and still left them with an additional $7.5 million in cash on the balance sheet, in addition to whatever cash was already there.

Q2. Doesn't Socius hold a lot of preferred stock that will be a future burden to ISCO?



A2. No, all of that has been retired as part of the capital restructuring announced in an 8-K filed June 11, 2010. As a result, Socius and its predecessor company, Optimus, hold no preferred shares of ISCO at all.

Q3. Is the company running out of money?



A3. Based on the monthly "burn" rate of about $550,000 for the last 15 months ($562,000 for the last quarter), the proceeds of the company's most recent financing of $7.5 million after the repayment of the outstanding preferred stock of Socius and Optimus would give the company at least 12 months of "runway," even without any additional revenues from operations, licensing or partnerships.



I could go on, but this is pretty long. Next week, I'll have more updates.

Arthritis Patient Successfully Treated With Fat Stem Cells Tells His Story

SAN DIEGO, CA--(Marketwire - June 28, 2010) - Medistem Inc. (PINKSHEETS: MEDS). Medistem collaborator Dr. Jorge Paz Rodriquez was invited to give a talk at Del Mar College in Texas by arthritis patient Dusty Durrill. The patient described a profound recovery after treatment with stem cells from his own fat tissue. Mr Durrill underwent a procedure in which a small amount of fat tissue was extracted by liposuction, stem cells where purified, and subsequently injected intravenously.

This procedure has been used successfully to treat thousands of animals suffering from arthritis in the United States (www.vet-stem.com). Use of patient's own stem cells is currently being performed in the United States (www.regenexx.com). Recently Dr. Paz published a paper describing scientific mechanisms of this treatment in collaboration with scientists from the University of California San Diego, University of Western Ontario, and Medistem Inc (Ichim et al. Autologous stromal vascular fraction cells: A tool for facilitating tolerance in rheumatic disease. Cell Immunol. 2010 Apr 8).

"I had treatment for my arthritis, I was not wheelchair bound but I was getting there... after stem cell treatment my arthritis symptoms disappeared," stated Mr. Durrill.

More than 200 people attended the lecture including the general public, patients and medical doctors. The lecture was focused on US and European clinical trials supporting the use of adult stem cells in conditions ranging from multiple sclerosis, to heart failure, to diabetes. A video of part of the lecture is available at http://www.kiiitv.com/younews/97165699.html.

Dr. Paz commented, "Mr. Durrill suffered from arthritis for more than ten years with severe pain in both knees and hips. He had difficulty standing and limited mobility. After stem cell therapy he started showing significant reduction in pain. Now about a month after therapy he is pain free and can move around easily."

Drs. Robert Harman, CEO of Vet-Stem and Thomas Ichim, CEO of Medistem, recently released a video discussing their publication on fat stem cell therapy for arthritis. The video is available at http://www.youtube.com/watch?v=3QQrwtp-KQQ.

Doctors are saying stem cell transplants are a promising new treatment to restore sight to individuals who have suffered severe eye damage. Dozens of patients whose eyes were injured after being splashed with caustic chemicals were able to see again after receiving a transplant of their own stem cells, according to The Associated Press.

Italian researchers reported that the transplants had worked completely in 82 of 107 eyes, including in one patient who sustained severe eye injuries some 60 years ago and has had his sight almost completely restored. The transplant worked at least partially in 14 other eyes, and the benefits have lasted for up to 10 years.

"This is great work, an absolutely great way to do it," said Dr. Douglas Lazzaro, chairman of ophthalmology at Long Island College Hospital. "It can only increase the success rate of these types of procedures."

Dr. Bruce Rosenthal, chief of low-vision programs at Lighthouse International, a nonprofit that fights vision impairment, called the stem cell transplants a very promising treatment. The procedure bypasses the risk of rejection posed by corneal transplants because the patient’s own stem cells are used.

"This is a major step in returning vision to someone who has lost it," Rosenthal says.

University of California ophthalmologist Ivan Schwab, who is not involved in the study, called the research "a roaring success."

Each year, stem cell transplants could offer the promise of healing to thousands of people who sustain chemical burns on their corneas, although they would not help those with macular degeneration, which involves the eye’s retina, or those with damage to the optic nerve. People who are blind in both eyes also would not be candidates for the transplant because some healthy tissue is required to undergo it, doctors explained.

The researchers who performed the transplants for the study, which was published online by the New England Journal of Medicine, removed stem cells from the patient’s good eye, grew them in the lab and put them back in the injured eye. There, they grew new corneal tissue that replaced the damaged tissue. None of the patients needed anti-rejection drugs.

For many years, adult stem cells have been used to treat disorders as varied as leukemia and sickle cell anemia. But fixing damaged eyes with a stem cell transplant is relatively new - and so far is not being done here.

"The U.S. is pretty stringent," Rosenthal says. "They won’t allow these procedures until they are FDA-approved and have gone through a lot of clinical testing. But even though it’s not ready for prime time, there is a lot of hope for the future."

Some 61 million Americans are at high risk for serious vision loss, according to Lighthouse International, and about 61 million individuals age 45 and older will have vision loss by 2015. A Lighthouse survey revealed that fewer than half (46%) of Americans get an annual eye exam.

(Reuters) - A U.S. appeals court on Friday reinstated a lawsuit that challenges an Obama administration policy for federal funding of some human embryonic stem cell research.

The unusual suit against the National Institutes of Health, backed by some Christian groups opposed to embryo research, argued that the NIH policy takes funds from researchers seeking to work with adult stem cells.

It also argues that new Obama administration guidelines on stem cell research are illegal.

The three-judge federal appeals panel did not rule on the merits of the lawsuit itself, but said two of the doctors involved had legal standing to file it.

A federal district court had earlier rejected the lawsuit, saying the challengers had no standing.

Stem cells are the body's master cells. There are several kinds, including those taken from days-old human embryos, which can give rise to all the cells and tissues in the body.

Some people oppose working with human embryonic stem cells, but President Barack Obama's administration reversed a policy that severely limited federal funding of such work.

The NIH will now pay for research using the cells, although it will not pay for the actual process of making the cells, which does involve human embryos. The use of federal funds to pay for the destruction of human embryos is forbidden by law.

The NIH also funds work with so-called adult stem cells, immature cells found throughout the body.

Dr. James Sherley, a biological engineer at Boston Biomedical Research Institute who opposes the use of embryonic stem cells, had argued that the guidelines violated the law by permitting research on stem cells derived from human embryos and would harm their work by increasing competition for limited federal funding.

Sherley and Theresa Deisher of Washington-based AVM Biotechnology were joined in their challenge by the Christian Medical Association, which opposes federal funding of embryonic stem cell research, and an adoption agency called Nightlight Christian Adoptions, which had argued that the guidelines reduced the number of embryos available for use in adoption.

Jeffrey Janus serves as director and senior vice president of operations of new CHI member International Stem Cell Corp. and president and chief executive officer of Lifeline Cell Technology, one of the company’s subsidiaries. International Stem Cell Corp. (ISCO.OB) is a publicly traded stem cell therapy company with research and manufacturing facilities in Oceanside, Calif., and Walkersville, Md. The company’s technology revolves around its discovery of a proprietary and unique class of stem cells called human parthenogenetic stem cells (hpSC). These cells have distinct medical, practical and ethical advantages over embryonic and adult stem cells. They allow immune-matched stem cells and therapeutic cells to be “banked” and available immediately for millions of patients who are in critical need and cannot wait to derive cells from their own bodies. In addition to Lifeline Cell Technology, the company has another subsidiary called Lifeline Skin Care.

Janus is trained in biochemistry and business management and has more than 20 years experience focused on cell-based businesses. He is a member of the team that discovered parthenogenesis and is published in the stem cell field. After joining International Stem Cell Corp., (ISCO) Janus subsequently founded Lifeline Cell Technology to meet a growing need for media and human cells in pharmaceutical drug screening, consumer product testing and basic research at universities and government laboratories and to provide revenue and operational infrastructure for ISCO. The CHI Blog recently caught up with Janus to find out the latest on the company.

Q: How did your company get started? A: We started this company based on the work of Elena Revazova, M.D., Ph.D., a scientist well known in Russia who had a dream of curing diabetes using embryonic stem cells. She came to the United States to work and her talent and expertise in growing human cells was discovered by ISCO’s founders, who decided to form a company around her knowledge and skill. At the time, U.S. President [George W.] Bush was restricting the use of embryonic stem cells on ethical grounds, and there were also patent issues around embryonic stem cells, as there still are. We recognized that the ethical issue was important, but medially the most important problem with stem cell therapy was likely to be immune rejection. We realized we could address these issues by developing the technology called parthenogenesis and mitigate delays from funding and restrictions by working in Russia. So Dr. Revazova went back to Russia, and we set up a collaboration in Moscow to begin her work with parthenogenesis. Today our company has all of the intellectual property rights to parthenogenesis, a very powerful technology. We have also recently brought in Andrey Semechkin, Ph.D. as our CEO. Dr. Semechkin is a well-known scientist in the field of systems analysis and an accomplished businessman.

Q: How does parthenogenesis work? A: It’s the derivation of stem cells from an unfertilized human egg. The ethical issue surrounding work with embryonic stem cells is caused by the fact that embryonic stem cells are derived from a fertilized embryo, which has the potential to be a human being. However, if you do not fertilize the egg and yet you can derive stem cells from it that are functional, you’re not destroying a viable human embryo—and that’s exactly what Dr. Revazova did. We perfected parthenogenesis and brought it back to the United States. As a result, we have been able to overcome the ethical issue surrounding using embryonic stem cells with parthenogenesis.

Q: What are your technology’s other advantages? A: Parthenogenesis makes embryonic stem cells (or what we call parthenogenetic stem cells) that can be immune matched to millions of people. Using embryonic stem cells, the way they are currently made, is sort of like trying to do a bone marrow transplant between one person and another picked at random without making sure you have a match. If someone needs to have a bone marrow transplant, they usually go to brothers or sisters first and try to do an immune match. For a different set of reasons a similar situation exists with blood transfusions, although type O blood can be given to almost everyone. Our cells are similar in that the parthenogenic stem cells can be immune matched to many people, and that’s the unique quality of our cells.

Q: What are the biggest opportunities for your business going forward? A: We are creating a bank of hpSC that are “pluripotent” and carry common immune types that will match a large percent of the U.S. population, and this is a huge opportunity. These will be clinical grade and will be made in our new manufacturing facility located in Oceanside, Calif. Our biggest opportunity is the potential ability of our stem cells to be universally utilized for therapy. Scientists across the world are working on embryonic stem cells and figuring out ways to make therapeutic cells such as liver cells or nerve cells for a whole host of diseases. Eventually these therapies will need a cell or process that will minimize immune rejection. Our cells can be immune matched to millions of persons and are thus a solution for this need. So in a way, much of the work that’s going on right now across the world with embryonic stem cells accrues to our benefit. In addition, we are focused in four distinct areas—diabetes, liver disease, retinal and corneal disease, and nerve disease. We are currently growing cells to cure corneal blindness and have actually grown cornea tissue. We’re working with the University of California, Irvine to grow cells with a retina for macular degeneration. We have grown cells that are very similar to liver cells that are also related to a cell type called beta cells, which may be useful for diabetes. Collaborations with companies and universities present strong opportunities, and we’ve collaborated with Novocell in San Diego to further our work with diabetes, and we’re collaborating with UC San Francisco to test our liver cells derived from our parthenogenic stem cells and with researchers in Germany to study nerve cells generated from our stem cells.

Q: Tell us a little bit about your subsidiaries. A: One unique thing about our company is that we are a research-oriented biotech company that actually has income. One of our subsidiaries, Lifeline Cell Technology, is growing very nicely (with a 150 percent increase in sales over the last year) by selling research products to grow human cells and study human disease. Lifeline has more than 70 products and will be releasing more than a dozen more in 2010. Lifeline Skin Care was created in 2009 based on our discovery that derivatives from our parthenogenetic stem cell technology have proven to be beneficial to human skin. Lifeline Skin Care is developing several products and is beginning early-stage clinical trials with these skin products. We anticipate that these skin care products will help to generate income and fund our continuing stem cell therapeutic research.

Q: What are your company’s greatest accomplishments so far? A. We have successfully created 10 human parthenogenetic stem cell lines, one which carries the most common immune type in the United States and matches over a hundred million persons across the world. We are a fast-growing company with more than 12 scientists working in various areas of therapy and product development. Our stem cells have proven to be able to create cells that may be useful in therapy, including liver-like cells, corneal cells, retinal cells, nerve cells and cell types that may ultimately be useful in the treatment of diabetes. We have set up collaborations with major universities and researchers across the world. The amazing thing about our company is that we have developed into a company that has manufacturing, products, sales, quality control, therapeutic research, and an accounting department in such a short time. We have all the workings of a fully functional product manufacturing and therapeutic research company. It amazes me that we are making sales, whereas most companies our size are basic research and development companies. We know how to make human cells and freeze, store and manipulate them so that they are clinical grade. I think our technology, our knowledge of cell culture and our ability to manufacture are three very strong reasons that we have been successful.

Cellonis Diabetes Stem Cell Therapy: A Chance for Insulin Independence and the Reversal of Complications

BEIJING, June 24 /PRNewswire-Asia/ -- Cellonis, a Beijing and HK-based biotech company, with its new personalized diabetes treatment concept has demonstrated an amazing improvement in their treated patients' conditions. The ongoing clinical study shows the treatment's best case could reconstruct a patient's natural insulin production and even reverse later complications like kidney failure. Treated patients may have the chance to return to the normal activities non-diabetes sufferers take for granted.

The clinical study, jointly conducted by scientists and doctors of the Cellonis clinical research team, aims to help patients be free from insulin and oral drugs, by reconstructing their natural insulin production damaged by either autoimmune disorder (T1DM) or hyperglycemia and also improve insulin sensitivity (T2DM). Using injections of autologous stem cells from the patient's bone marrow, the research team believes that this therapy could help patients return to a life without annoying everyday injections and drugs.

"Most of the patients in our clinical study are now taking less synthetic insulin or oral drugs for BG control," says Dr. Chase Dai, Chief Medical Officer at Cellonis. "We appear to have restored the biological insulin producing function of the body. We are excited to see that some patients have been treatment-free for five months now, and we believe the effect of the stem cell therapy can last much longer. We were also encouraged by some other happy surprises during the clinical study.

"For example, this therapy appears to reverse chronic kidney failure. It was a surprise for all of my team to observe that the kidney function of a 75- year-old patient improved remarkably."

This patient had suffered from diabetes for years, gradually developing diabetic foot and nephropathy. He can now walk freely after having been confined to bed or a wheelchair for six months, and his quality of life has improved significantly. Moreover, he only needs kidney dialysis one time a week instead of three times. In a follow-up visit he excitedly told us that he was hopeful that in the near future he could be completely rid of diabetes.

Diabetes, an increasingly spreading disease, can lead to life-threatening diseases such as blindness, amputation, strokes, or kidney failure in its natural course. Current treatments, including insulin, cannot change this situation.

"We believe that our stem cell therapy will bring promising hope for patients suffering from diabetes and its complications," comments Cindy Hao, CEO of Cellonis. "Personalized diabetes therapies for patients of various conditions will be developed by Cellonis in the near future. We believe what we have restored for patients will not only be their natural insulin production, but also a normal life filled with the activities non-diabetes sufferers can enjoy daily."

Cellonis Biotechnologies focuses on R&D and the clinical application of novel personalized stem cell therapies and immunotherapies for patients with diseases including cancer, diabetes and central nervous system disorders.

ABOUT INTERNATIONAL STEM CELL CORPORATION (ISCO.OB):

International Stem Cell Corporation is a California-based biotechnology company focused on therapeutic and research products. ISCO's core technology, parthenogenesis, results in creation of pluripotent human stem cells from unfertilized oocytes (eggs). hpSCs avoid ethical issues associated with the use or destruction of viable human embryos. ISCO scientists have created the first parthenogenic, homozygous stem cell line that can be a source of therapeutic cells with minimal immune rejection after transplantation into hundreds of millions of individuals of differing sexes, ages and racial groups. This offers the potential to create the first true stem cell bank, UniStemCell^(TM), while avoiding the ethical issue of using fertilized eggs. ISCO also produces and markets specialized cells and growth media for therapeutic research worldwide through its subsidiary Lifeline Cell Technology. More information is available at ISCO's website, http://www.internationalstemcell.com.
