SAN DIEGO, CA--(Marketwire -06/04/12)- Medistem Inc. (MEDS) announced today positive safety data from the first 5 patients enrolled in the Non-Revascularizable IschEmic Cardiomyopathy treated with Retrograde COronary Sinus Venous DElivery of Cell TheRapy (RECOVER-ERC) trial. The clinical trial uses the company's "Universal Donor" Endometrial Regenerative Cells (ERC) to treat Congestive Heart Failure (CHF).
According to the study design, after 5 patients enter the trial, they must be observed for a two month time period before additional patients are allowed to enter the study. Patient data was analyzed by the study's independent Data Safety Monitoring Board (DSMB), which concluded that based on lack of adverse effects, the study be allowed to continue recruitment.
"Medistem is developing a treatment for CHF that uses a 30-minute catheter-based procedure to administer the ERC stem cell into the patients' hearts. The achievement of 2 month patient follow-up with no adverse events is a strong signal for us that our new approach to this terrible condition is feasible," said Thomas Ichim, CEO of Medistem.
The RECOVER-ERC trial will treat a total of 60 patients with end-stage heart failure with three concentrations of ERC stem cells or placebo. The clinical trial is being conducted by Dr. Leo Bockeria, Chairman of the Backulev Centre for Cardiovascular Surgery, in collaboration with Dr. Amit Patel, Director of Clinical Regenerative Medicine at University of Utah.
"As a professional drug developer, I am very optimistic of a stem cell product that can be used as a drug. The ERC stem cell can be stored frozen indefinitely, does not need matching with donors, and can be injected in a simple 30-minute procedure into the heart," said Dr. Sergey Sablin, Vice President of Medistem and co-founder of the multi-billion dollar NASDAQ company Medivation.
Currently patients with end-stage heart failure, such as the ones enrolled in the RECOVER-ERC study, have no option except for heart transplantation, which is limited by side effects and lack of donors. In contrast to other stem cells, ERC can be manufactured inexpensively, do not require tissue matching, and can be administered in a minimally-invasive manner. Animal experiments suggest ERC are more potent than other stem cell sources at restoring heart function. The FDA has approved a clinical trial of ERC in treatment of critical limb ischemia in the USA.
About Medistem Inc. Medistem Inc. is a biotechnology company developing technologies related to adult stem cell extraction, manipulation, and use for treating inflammatory and degenerative diseases. The company's lead product, the endometrial regenerative cell (ERC), is a "universal donor" stem cell being developed for critical limb ischemia and heart failure. A publication describing the support for use of ERC for this condition may be found at http://www.translational-medicine.com/content/pdf/1479-5876-6-45.pdf.

Stem Cell Treatment for Heart Disease
The head of a stem cell company has responded to a warning letter issued by the U.S. Food and Drug Administration that cites several violations at the company that derives stem cells from adipose tissue or body fat.
Dr. Steven Victor of IntelliCell BioSciences said it would be moving to a new facility next month that it believes will address the current good manufacturing practice issues referred to in the warning letter It has also hired consultants with FDA-compliance experience that will help bring its new facilities in compliance with the FDA. Victor added that the company will address all of the FDAs observations on April 3.
The New York company received a warning letter dated March 13 that was published on the FDAs website yesterday. The letter said that the process that the company uses to produce stem cells from adipose tissue did not meet the FDAs definition of minimal manipulation for structural tissue such as adipose tissue.

CARLSBAD, Calif.--(BUSINESS WIRE)--
International Stem Cell Corporation (OTCBB: ISCO.OB - News) http://www.internationalstemcell.com today announced that the Company has developed new technologies to commercialize the use of human parthenogenetic stem cells (hpSC) to treat human diseases. The methods announced today are capable of producing populations of stem cells and their therapeutically valuable derivatives not only to a higher level of purity but also at a cost that is approximately several times lower than previously reported techniques.
ISCOs research team has developed a new method to derive high-purity populations of neural stem cells (NSC) from hpSC and further differentiate them into dopaminergic neurons. This method is capable of generating sufficient quantities of neuronal cells for ISCOs pre-clinical and clinical studies and is highly efficient as it requires substantially less time and labor in addition to using fewer costly materials than traditional methods. ISCOs technologies make possible the creation of billions of neuronal cells necessary for conducting such studies from a small batch of stem cells.
ISCO has also announced today that it has developed a new high-throughput cell culture method for growing human parthenogenetic stem cells (hpSC) in large quantities. This new technique is easily scalable and can produce the quantities of cGMP grade hpSC necessary for commercial and therapeutic applications.
One of the most challenging issues in commercializing stem cell based treatments is creating high-purity populations of stem cell derivatives at a reasonable cost. I believe the new methods we have developed solve this important problem and help position us for future clinical studies, says Dr. Ruslan Semechkin, Vice President, R&D.
About International Stem Cell Corporation
International Stem Cell Corporation is focused on the therapeutic applications of human parthenogenetic stem cells (hpSCs) and the development and commercialization of cell-based research and cosmetic products. ISCO's core technology, parthenogenesis, results in the 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 for hundreds of millions of individuals of differing genders, ages and racial background with minimal immune rejection after transplantation. hpSCs offer the potential to create the first true stem cell bank, UniStemCell. ISCO also produces and markets specialized cells and growth media for therapeutic research worldwide through its subsidiary Lifeline Cell Technology, and stem cell-based skin care products through its subsidiary Lifeline Skin Care (www.lifelineskincare.com).

Tampa, Fla. (June 4, 2012) When autologous (self-donated) lung-derived mensenchymal stem cells (LMSCs) were transplanted endoscopically into 13 adult female sheep modeled with emphysema, post-transplant evaluation showed evidence of tissue regeneration with increased blood perfusion and extra cellular matrix content. Researchers concluded that their approach could represent a practical alternative to conventional stem cell-based therapy for treating emphysema.
The study is published in Cell Transplantation (21:1), now freely available on-line at http://www.ingentaconnect.com/content/cog/ct/.
"Mensenchymal stem cells are considered for transplantation because they are readily available, highly proliferative and display multi-lineage potential," said study corresponding author Dr. Edward P. Ingenito of the Brigham and Women's Hospital Division of Pulmonary and Critical Care Medicine. "Although MSCs have been isolated from various adult tissues - including fat, liver and lung tissues - cells derived from bone marrow (BM) have therapeutic utility and may be useful in treating advanced lung diseases, such as emphysema."
However, according to the authors, previous transplantation studies, many of which used an intravenous delivery method, have shown that BM-MSCs have been only marginally successful in treating lung diseases. Further, therapeutic responses in those studies have been limited to animal models of inflammatory lung diseases, such as asthma and acute lung injury.
To try and answer the questions surrounding the utility of BM-MSCs for treating advanced emphysema, a disease characterized by tissue destruction and loss of lung structural integrity, for this study the researchers isolated highly proliferative, mensenchymal cells from adult lung parenchyma (functional tissue) (LMSCs) and used an endoscopic delivery system coupled with a scaffold comprised of natural extracellular matrix components.
"LMSCs display efficient retention in the lung when delivered endobronchially and have regenerative capacity through expression of basement membrane proteins and growth factors," explained Dr. Ingenito.
However, despite the use of autologous cells, only a fraction of the LMSCs delivered to the lungs alveolar compartment appeared to engraft. Cell death likely occurred because of the failure of LMSCs to home to and bind within their niche, perhaps because the niche was modified by inflammation or fibrosis. These cells are attachment-dependent and failure to attach results in cell death."
Their findings did suggest, however, that LMSCs were capable of contributing to lung remodeling leading to documented functional improvement rather than scarring 28 days post transplantation.

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.

MEDIA RELEASE
A*STAR Scientists Make Groundbreaking Discovery on Stem Cell Regulation
New link between polyamine levels and embryonic stem cell state deepens our understanding of embryonic stem cell regulation which is a key step in bringing cellular therapies from the laboratory to the clinic.
1. A*STAR scientists have for the first time, identified that precise regulation of polyamine[1] levels is critical for embryonic stem cell (ESC) self-renewal the ability of ESCs to divide indefinitely and directed differentiation. This paper is crucial for better understanding of ESC regulation and was published in the journal Genes & Development on 1st March by the team of scientists from the Institute of Medical Biology (IMB), a research institute under the Agency for Science, Technology and Research (A*STAR).
2. Embryonic stem cells hold great potential for the development of cellular therapies, where stem cells are used to repair tissue damaged by disease or trauma. This is due to their unique ability to renew themselves and differentiate into any specific types of cell in the body. One of the challenges with cellular therapies is ensuring that ESCs are fully and efficiently differentiated into the correct cell type. This study sheds light on understanding how ESCs are regulated, which is essential to overcome these challenges and turn the vision of cell therapies into reality.
3. Using a mouse model, the team of scientists from IMB showed that high levels of Amd1[2], a key enzyme in the polyamine synthesis pathway, is essential for maintenance of the ESC state and self renewal of ESCs. To further demonstrate the critical role of Amd1 in ESC self-renewal, the scientists showed that increasing Amd1 levels led to delayed ESC differentiation. The research also revealed that downregulation of Amd1 was necessary for differentiation of ESCs into neural precursor cells and that Amd1 is translationally regulated by a micro-RNA (miRNA), the first ever demonstration of miRNA-mediated regulation of the polyamine pathway.
4. While the polyamine pathway is well established and polyamines are known to be important in cancer and cell proliferation, their role in ESC regulation until now was unknown. This novel discovery, linking polyamine regulation to ESC biology, came about when the team set up a genome-wide screen to look for mRNAs under translational control in order to identify new regulators of ESC differentiation to neural precursor cells.
6. Dr Leah Vardy, Principle Investigator at the IMB and lead author of the paper, said, The polyamines that Amd1 regulate have the potential to regulate many different aspects of self renewal and differentiation. The next step is to understand in more detail the molecular targets of these polyamines both in embryonic stem cells and cells differentiating to different cellular lineages. It is possible that manipulation of polyamine levels in embryonic stem cells through inhibitors or activators of the pathway could help direct the differentiation of embryonic stem cells to more clinically useful cell types.
7. Prof. Birgitte Lane, Executive Director of IMB, said, This is a fine piece of fundamental research that will have breakthrough consequences in many areas and can bring about far-reaching applications. Developing cellular therapies is just one long-term clinical benefit of understanding ESC biology, which can also help develop stem cell systems for disease modeling, developing new drugs as well as a tool for researchers to answer other biological questions.

:: 01, Mar 2012 :: A*STAR SCIENTISTS MAKE GROUNDBREAKING DISCOVERY ON STEM CELL REGULATION
By Bonnie James Deputy News Editor The stem cell and regenerative therapy programme, constituting a major part of research at Qatar Cardiovascular Research Centre (QCRC), has important clinical and scientific implications, co-chairman Prof Sir Magdi Yacoub has said. He was giving a keynote presentation at the Qatar International Conference on Stem Cell Science and Policy 2012, which concluded on Thursday at Qatar National Convention Centre. Myocardium (the muscular tissue of the heart) regeneration and tissue engineering and valves tissue engineering are among the focal areas at QCRC, which aims to establish in Qatar an internationally competitive centre of excellence for cardio-vascular research. QCRC, which has a heart muscle lab and a tissue engineering, regeneration lab, works with a mission to maintain a translational focus, relevant to the development of health policy and practice, and provide opportunities for capacity building, professional development and research collaborations in Qatar. It is also meant to provide opportunities for biotechnology development in Qatar and contribute to cardio-vascular health in the developing world through improved knowledge base, capacity building and development of appropriate tools and strategies focused on poorer countries. Cardio-vascular diseases (CVDs) kill 17mn people per year globally and there is particularly high incidence in the Middle East and Gulf region, Prof Yacoub pointed out. The incidence of CVDs is three times more in the region than in the UK, the US or Europe. Smoking, one of the main reasons for CVDs, is also increasing in the eastern Mediterranean region compared to the Americas. There is a significant lack of clinical, epidemiological and genetic data from this region and an overwhelming need exists to better understand epidemiology and disease mechanisms of CVDs. Research should then be linked to development of appropriate tools and strategies to strengthen prevention, diagnosis and treatment, he said. Pointing out that heart transplant options for those suffering from severe heart failure are becoming increasingly rare, Prof Yacoub observed that the number of donor hearts is going down globally. While we used to do up to 130 heart transplants a year at Royal Brompton and Harefield Hospitals in the UK in the late 80s, now we would be lucky to do 20, he said while emphasising the need to focus more on the reversibility of heart failure. Few recent drug trials have shown evidence of minor reverse remodelling and there have been near-complete reversal of almost every change in myocardium in some patients. There are unprecedented opportunities to unravel the secrets of heart failure at cellular and molecular levels, he stressed.
