For the past eight years, scientists who wanted to use federal funds for research on human embryonic stem cells had to restrict their studies to 21 cell lines approved by the National Institutes of Health. But an analysis by a researcher at the Stanford University School of Medicine suggests that only two of those lines have been used routinely. http://www.physorg.com/news168875469.html Biology Fri, 07 Aug 2009 14:52:00 EST news168875469 Scientists have long wondered how melanoma cells travel from primary tumors on the surface of the skin to the brain, liver and lungs, where they become more aggressive, resistant to therapy, and deadly. Now, scientists from NYU Langone Medical Center have identified the possible culprit -a short strand of RNA called microRNA (miRNA) that is over-expressed in metastatic melanoma cell lines and tissues. http://www.physorg.com/news153407237.html Medicine & Health Mon, 09 Feb 2009 13:07:45 EST news153407237 For patients with a particularly aggressive form of skin cancer - malignant melanoma - stress, including that which comes from simply hearing that diagnosis, might amplify the progression of their disease. http://www.physorg.com/news152540593.html Medicine & Health Fri, 30 Jan 2009 12:23:46 EST news152540593 UC Davis Cancer Center researchers have discovered a metabolic deficiency in pancreatic cancer cells that can be used to slow the progress of the deadliest of all cancers. http://www.physorg.com/news145215143.html Medicine & Health Thu, 06 Nov 2008 17:32:23 EST news145215143 In a potential breakthrough for the performance horse industry (such as racing and polo), Melbourne scientists are aiming to harness stem cells to repair tendon, ligament, cartilage and bone damage in horses. http://www.physorg.com/news143803013.html Biology Tue, 21 Oct 2008 10:16:53 EST news143803013 Victoria and New South Wales have put aside their competitive interstate rivalry to collaborate on a stem cell research project, as announced by Innovation Minister Gavin Jennings and NSW Minister for Science and Medical Research, Verity Firth, today. http://www.physorg.com/news139743070.html Medicine & Health Thu, 04 Sep 2008 10:31:10 EST news139743070 A set of new stem cell lines will make it possible for researchers to explore ten different genetic disorders -including muscular dystrophy, juvenile diabetes, and Parkinson's disease -in a variety of cell and tissue types as they develop in laboratory cultures. http://www.physorg.com/news137341842.html Biology Thu, 07 Aug 2008 15:30:42 EST news137341842 (PhysOrg.com) -- Harvard Stem Cell Institute researcher George Q. Daley, associate director of the Stem Cell Program at Children's Hospital Boston, has with HSCI colleagues Chad Cowan and Konrad Hochedlinger of Massachusetts General Hospital produced a robust new collection of disease-specific stem cell lines, all of which were developed using the new induced pluripotent stem cell (iPS) technique. The work is described in a paper published in today's online edition of the journal Cell. http://www.physorg.com/news137338436.html Biology Thu, 07 Aug 2008 14:33:56 EST news137338436 In a collaborative project scientists from the Max-Planck-Institute for Molecular Genetics in Berlin (MPI MolGen), Germany and Genomatix with a business in Munich, Germany and Ann Arbor, MI, USA, applied next generation sequencing and analysis methods to generate an unprecedented view at the human transcriptome. http://www.physorg.com/news134743567.html Biology Tue, 08 Jul 2008 13:46:07 EST news134743567
