Doctors at the All India Institute of Medical Sciences (AIIMS) have conducted a stem cell transplant on a multiple sclerosis (MS) patient. They believe this is the first recorded case of an autologous stem cell therapy where the donor and recipient are the same person for MS in the country.

Six months after the transplant, doctors say the spread of MS, an autoimmune disease that affects the brain and spinal cord, appears to have been contained but the therapy cannot be declared a success until the patient is monitored for at least a year.

International trials have demonstrated that this transplant can restrict the spread of the disease in advanced patients, and may even reverse symptoms in early stages in some patients.

Thirty-two-year-old Rohit Yadav, a commerce graduate from Delhi University, was diagnosed with the neurological disorder in 2010. In March this year, after trying all possible conventional treatment options, doctors at AIIMS finally decided on stem cell therapy.

Dr Kameshwar Prasad, professor of neurology who has been monitoring Yadav, said: The primary purpose of autologous stem cell transplant is to control the spread of lesions. We extract the patients own stem cells, treat and inject the stem cells back. Ever since the procedure, the patient has been completely stable. To the best of our knowledge, this is the first case of stem cell therapy for MS.

In MS, the bodys own immune system attacks the myelin sheath that coats nerves, slowly destroying the central nervous system. Symptoms range from numbness and weakness in the limbs to sudden loss of balance and coordination, blurred vision and paralysis and, at the most advanced stage, disability.

SAN CARLOS, Calif.--(BUSINESS WIRE)--

Cellerant Therapeutics Inc., a biotechnology company developing novel hematopoietic stem cell-based cellular and antibody therapies for blood disorders and cancer, announced today that it has been awarded a Small Business Innovation Research (SBIR) Phase 1 contract and a Phase 2 option from the National Cancer Institute (NCI) valued up to $1,683,503. The SBIR Contract funds the development of CLT-009, a first-in-class, human allogeneic Megakaryocyte Progenitor Cell therapy for the treatment of thrombocytopenia in cancer patients and allows the Company to conduct studies to enable an Investigational New Drug (IND) Application to be filed with the FDA in the next two years.

Thrombocytopenia is characterized as a significant reduction in the concentration of circulating platelets. Platelets are crucial in the process of coagulation to stop bleeding, and thrombocytopenia can increase the risk of severe bleeding in patients. It is becoming an increasingly common problem among oncology patients and a significant dose-limiting toxicity, especially in the treatment of hematological malignancies. Chemotherapy and radiation therapy are the most common causes of thrombocytopenia because the platelet-producing cells, megakaryocytes, and their precursors are highly sensitive to myelosuppressive cytotoxics and ionizing radiation. Thrombocytopenia typically occurs during the initial cycles of high-dose chemotherapy and radiation therapy, usually 614 days after administration. According to Datamonitor, the estimated incidence of cancer patients who suffer from significant chemotherapy-induced thrombocytopenia worldwide was approximately 200,000 in 2008.

Occurrence of severe thrombocytopenia may require dose reductions for chemotherapy regimens which can impact subsequent disease control and survival, especially in the treatment of hematological malignancies such as acute leukemia and high-risk myelodysplastic syndrome. Current treatment options include platelet transfusions which are costly and labor intensive and are associated with risks such as contamination and transmission of viral and bacterial infections. Recombinant human interleukin-11 is the only approved agent for chemotherapy induced thrombocytopenia but its use is limited and has only modest efficacy and significant side effects. CLT-009, a human Megakaryocyte Progenitor Cell product, would be an alternative treatment option, providing the critical megakayocyte progenitor cellular support to rapidly produce platelets in vivo and shorten the duration of severe thrombocytopenia following chemotherapy treatment.

We are delighted to receive this contract from NCI to support the development of our novel, off-the-shelf, platelet product and address a high unmet need, said Ram Mandalam, Ph.D., President and Chief Executive Officer of Cellerant Therapeutics. This contract allows us to not only leverage our experience in developing cellular therapies but also provides us with the ability to bring CLT-009 closer to the clinic. Our unique product portfolio, which now includes CLT-009, along with our CLT-008 myeloid progenitor cell product and our therapeutic antibodies targeting cancer stem cells, demonstrates our continued commitment to developing novel products for the benefit of cancer patients.

In addition to this SBIR contract, Cellerant has previously received grants from the National Institute of Health (NIH) in 2008 2010 to conduct research studies in platelet recovery which it has successfully completed. In its previous studies, Cellerant demonstrated that megakaryocyte progenitor cells were able to produce human platelets in preclinical models with in vivo functionality similar to that of normal human platelets.

This program is funded with Federal funds from the National Institute of Health, Department of Health and Human Services, under Contract No.HHSN261201200076C.

STOCKHOLM (AFP) - Shinya Yamanaka of Japan and John Gurdon of Britain won the Nobel Prize on Monday for work in cell programming, a frontier that has raised dreams of replacement tissue for people crippled by disease.

The two scientists found that adult cells can be transformed back to an infant state called stem cells, the key ingredient in the vision of regenerative medicine.

"Their findings have revolutionised our understanding of how cells and organisms develop," the Nobel jury declared. "By reprogramming human cells, scientists have created new opportunities to study diseases and develop methods for diagnosis and therapy."

Among those who acclaimed the award were Britain's Royal Society; Ian Wilmut, the "father" of Dolly the cloned sheep; and a leading ethicist, who said it eased a storm about the use of embryonic cells.

Stem cells are precursor cells which differentiate into the various organs of the body.

They have stirred huge excitement, with hopes that they can be coaxed into growing into replacement tissue for victims of Alzheimer's, Parkinson's and other diseases.

Gurdon, born in 1933, said he was grateful but also surprised by the honour, since his main research was done more than 40 years ago.

In 1962, he discovered that the DNA code in the nucleus of an adult frog cell held all the information to develop into every kind of cell.

This meant that an adult cell could in essence be reprogrammed.

His landmark discovery was initially met with scepticism, as the journey from immature to specialised cell was previously deemed irreversible.

Stem cell pioneers win Nobel for medicine

British researcher John Gurdon and Shinya Yamanaka from Japan have shared the Nobel prize for medicine or physiology.

The two pioneers of stem cell research were awarded the prize for transforming specialised cells into stem cells, which can become any other type of cell in the body.

John Gurdon discovered in 1962 that the specialisation of cells is reversible. In a classic experiment, he replaced the immature cell nucleus in an egg cell of a frog with the nucleus from a mature intestinal cell. This modified egg cell developed into a normal tadpole. The DNA of the mature cell still had all the information needed to develop all cells in the frog.

Shinya Yamanaka discovered more than 40 years later, in 2006, how intact mature cells in mice could be reprogrammed to become immature stem cells. Surprisingly, by introducing only a few genes, he could reprogram mature cells to become pluripotent stem cells, i.e. immature cells that are able to develop into all types of cells in the body.

These groundbreaking discoveries have completely changed our view of the development and cellular specialisation.

By reprogramming human cells, scientists have created new opportunities to study diseases and develop methods for diagnosis and therapy.

Stem Cell Researchers Share Nobel Medicine Prize

NEW YORK, Oct. 8, 2012 (GLOBE NEWSWIRE) -- NeoStem, Inc. (NYSE MKT:NBS), an emerging leader in the fast growing cell therapy market, announced today that data from its collaborative studies with the University of Michigan School of Dentistry further expands the therapeutic potential of its proprietary regenerative cell therapy product, "VSELSTM" (very small embryonic-like stem cells), by demonstrating bone regeneration capabilities in a study published online ahead of print1 in the journal Stem Cells and Development (DOI: 10.1089/scd.2012.0327). The paper highlights that human VSEL stem cells form human bone when implanted in the bone tissue of SCID mice.

VSELs are a population of stem cells found in adult bone marrow with potential regenerative properties similar to those of embryonic stem cells. NeoStem has shown that these cells can be mobilized into the peripheral blood, enabling a minimally invasive means for collecting what NeoStem believes to be a population of stem cells that have the potential to achieve the positive benefits associated with embryonic stem cells without the ethical or moral dilemmas or the potential negative effects known to be associated with embryonic stem cells.

This published controlled study, funded by NIH and led by Dr. Russell Taichman, Major Ash Collegiate Professor and Co-Director of the Scholars Program in Dental Leadership Department of Periodontics & Oral Medicine, University of Michigan and Dr. Aaron Havens, Department of Orthodontics and Pediatric Dentistry at University of Michigan, involved isolating G-CSF mobilized VSEL stem cells from the blood of healthy donors and transplanting them into burr holes made in the cranial bones of SCID mice. After three months, it was observed that the implanted VSEL stem cells had differentiated into human bone tissue in the crania of the mice. Dr. Taichman stated, "I believe this work represents a true partnership between Industry and Academic Institutions. Our findings that VSEL cells can generate human bone in animals would not have been feasible without the help and vision that Dr. Denis Rodgerson and his team at NeoStem brought to the table. It was my privilege to have been a part of this collaborative effort, and I see the resulting data as a significant milestone in stem cell therapy development. It is truly inspiring."

Dr. Robin Smith, Chairman and CEO of NeoStem, added, "This is very exciting data that we believe will be the foundation for future VSEL stem cell studies of bone regeneration in humans. We look forward to moving the development work from the laboratory into the clinic to develop a therapeutic stem cell product to enhance bone formation in humans."
