ScienceDaily (Mar. 5, 2012) Researchers from the Perelman School of Medicine at the University of Pennsylvania report this month in Cancer Research a universal approach to personalized cancer therapy based on T cells. It is the first time a system for making an adaptable, engineered T-cell to attack specific tumor types has been proposed, depending on which abnormal proteins, called antigens, are expressed by individual patients' tumor cells. For now, the system is being refined in experiments using healthy donor T cells and animal models of human cancer, with the aim to introduce the personalized cells into patients in the future, explains senior author Daniel J. Powell Jr., Ph.D., a research assistant professor of Pathology and Laboratory Medicine with Penn's Ovarian Cancer Research Center. Tumor antigens are potential targets of an immune response, and identifying which antigens a patient's tumor cells express would be helpful in designing cancer therapy for that individual. Any mutated protein produced in a tumor cell can act as a tumor antigen. Many tumor cells have surface proteins that are inappropriately expressed for the cell type, or are only normally present during embryonic development. Still other tumor cells display cell surface proteins that are rare or … Continue reading →

NEW YORK, NY--(Marketwire -03/05/12)- February was a challenging month for stem cell stocks. TickerSpy's Stem Cell Stocks Index (RXSTM) has slipped nearly 13 percent over the last month -- underperforming the S&P 500 by close to 17 percent over that time frame. Despite the drop in investor optimism, new research continues to propel the industry forward.

"This has never been accomplished before, despite a decade of cell therapy trials for patients with heart attacks. Now we have done it," Eduardo Marban, director of the Cedars-Sinai Heart Institute and one of the study's co-authors, said in a statement. "The effects are substantial." In another study, researchers led by Jonathan Tilly, director of the Vincent Center for Reproductive Biology at Massachusetts General Hospital, argue they've discovered the ovaries of young … Continue reading →

SAN DIEGO, March 5, 2012 /PRNewswire/ --Histogen Inc., a regenerative medicine company, and Suneva Medical, a privately-held aesthetics company, today announced that they have entered into a license agreement for physician-dispensed aesthetic products containing Histogen's proprietary multipotent cell conditioned media (CCM). Under the terms of this license agreement, Suneva Medical has acquired exclusive U.S. licensing rights to Histogen's multipotent CCM and the ReGenica branded line of products for topical applications in the licensed market. Suneva Medical will manufacture the ReGenica product line and market it to aesthetic practitioners throughout the U.S. Histogen will receive a transfer price on the CCM, as well as royalties on future sales of ReGenica and product line extensions. "First, let me say that, as the first step in expanding our business, we are very excited about this particular opportunity as the advent of regenerative medicine is upon us. One of our key business objectives is to find novel products that complement our rapidly growing dermal filler business. We believe Histogen's innovative technology coupled with our proven experience of developing and marketing aesthetic products is a winning combination as it enables us to offer our customers a differentiated product line," stated Nicholas Teti, Chairman and Chief … Continue reading →

A new treatment for cancer in dogs has become available in Australia. Developed by Pfizer Animal Health, the medicine is administered orally and works by killing cancer cells and cutting off the blood supply to skin-based mast cell tumours. The potentially lethal form of canine cancer can appear as wart-like lumps on the surface of the skin. Vet Rod Straw, founder of the Australian Animal Cancer Foundation and the Brisbane Veterinary Specialist Centre, was one of the first in Australia to use the new treatment. He said one in four dogs developed a tumour at some stage in their life. "When an owner is given the devastating news that their beloved pet has cancer, their primary concern is to limit their dog's day-to-day pain and suffering," Dr Straw said. "This new medicine gives vets and owners the best chance to do this." Dr Straw said before the new treatment vets had to rely on human cancer medicines as the only option for treating mast cell tumours. "Given that these medicines weren't developed with canine cancer in mind, it is only through trial and error that we as vets were able to identify a safe dose and work out how to … Continue reading →

WASHINGTON, DC--(Marketwire -03/05/12)- The Alliance for Regenerative Medicine issued the following statement today: "An article about stem cell treatments taking place in Texas published by Nature last week is extremely troubling. The article suggests that patients are being administered stem cell treatments that have not been systematically demonstrated to be safe and effective therapies through the established FDA regulatory process. "Cell therapy treatments, including those using adult stem cells, hold the promise of providing patients with treatments and cures for numerous diseases and disabilities. However, FDA regulation is key to ensuring that the treatments available to patients are safe and effective. "The Alliance for Regenerative Medicine (ARM), a non-profit organization whose mission is to promote increased funding and development of regenerative medicine products, believes cell therapy and regenerative medicine products, including autologous cell therapy products, must go through the rigorous safety testing that is part of the FDA regulatory process before they can be marketed to the public. These regulations are designed to promote safe collection, manufacture, storage, and use of human cells, and cellular and tissue based products. ARM members comply with these rules because they know that FDA oversight helps to prevent patients from exposure to potentially unsafe … Continue reading →
