One kind of stem cell, those referred to as 'facultative', form part -- together with other cells -- of tissues and organs. There is apparently nothing that differentiates these cells from the others. However, they have a very special characteristic, namely they retain the capacity to become stem cells again. This phenomenon is something that happens in the liver, an organ that hosts cells that stimulate tissue growth, thus allowing the regeneration of the organ in the case of a transplant. Knowledge of the underlying mechanism that allows these cells to retain this capacity is a key issue in regenerative medicine. Headed by Jordi Casanova, research professor at the Instituto de Biologa Molecular de Barcelona (IBMB) of the CSIC and at IRB Barcelona, and by Xavier Franch-Marro, CSIC tenured scientist at the Instituto de Biologa Evolutiva (CSIC-UPF), a study published in the journal Cell Reports reveals a mechanism that could explain this capacity. Working with larval tracheal cells of Drosophila melanogaster, these authors report that the key feature of these cells is that they have not entered the endocycle, a modified cell cycle through which a cell reproduces its genome several times without dividing. "The function of endocycle in living … Continue reading →

Irelands first human stem cell trial using lab-grown cells is due to get underway in Galway in the new year following approval from the medicines watchdog. The trial will involve extracting adult mesenchymal stem cells (MSC) from the bone marrow of patients with a condition known as critical limb ischemia (CLI) a severe blockage of the arteries resulting in marked reduction in blood flow to the extremities. Reduction in blood flow to the legs puts patients at risk of gangrene, ulceration, and amputation, and the Galway trial will look at the use of MSCs to grow new stems cells which will then be injected back into the patients leg with the hope of growing new blood cells and improving circulation. The harvested stem cells will be grown to much greater quantities in a highly specialised lab before being injected back into the patients leg. Tim OBrien, director of the Galway-based Regenerative Medicine Institute, said their research was focused on whether MSC therapy could improve blood flow to the legs in patients with CLI a condition common in diabetics and therefore avoid the need for amputation. The trial is aimed predominantly at testing the safety and feasibility of what is very … Continue reading →

Chicago, Illinois (PRWEB) October 30, 2014 On October 26th at the Mid American Regenerative and Cellular Medicine Showcase in Chicago, leading applied stem cell research scientist Neil Riordan, PhD and Orthopedic Surgeon, Dr. Wade McKenna presented talks on New Techniques for Enhancing Stem Cell Therapy Effectiveness and Orthopedic Surgical Applications For Stem Cells. Dr. Riordan focused on historical medical uses of amniotic membrane and the properties of AlphaGEMS that include: wound healing; inflammation and pain reduction; fibrosis risk reduction; growth factor source; adhesion reduction; regeneration support and stem cell enhancement, specifically regarding the mesenchymal stem cells contained within BMAC. Dr. McKenna discussed the latest applications of BMAC stem cells in orthopedic surgeries like anterior cruciate ligament (ACL) reconstruction and how BMAC injections can virtually eliminate infection risk, reduce complications, increase graft strength, reduce post-surgical inflammation and significantly reduce recovery time. Dr. McKenna also talked about how bone marrow can now be safely and relatively painlessly harvested using his patented BioMAC catheter under local, not general anesthesia. Dr. Riordan and Dr. McKenna are co-founders of the Riordan-McKenna Institute (RMI), which will be opening soon in Southlake, Texas. RMI will specialize in regenerative orthopedics including non-surgical stem cell therapy and stem cell-enhanced … Continue reading →
