Scientists from the University of Wisconsin, USA, report in the journal Development the successful generation from human embryonic stem cells of a type of cell that can make myelin, a finding that opens up new possibilities for both basic and clinical research. http://www.physorg.com/news158475622.html Biology Thu, 09 Apr 2009 06:00:51 EST news158475622 University of Pennsylvania School of Medicine researchers have discovered how the expression of the Sonic hedgehog gene is regulated during brain development and how mutations that alter this process cause brain malformations. The results appear online this month in Nature Genetics. http://www.physorg.com/news144422498.html Medicine & Health Tue, 28 Oct 2008 14:21:38 EST news144422498 (PhysOrg.com) -- Yale University scientists today reported evidence suggesting that the tiny cilia found on brain cells of mammals, thought to be vestiges of a primeval past, actually play a critical role in relaying molecular signals that spur creation of neurons in an area of the brain involved in mood, learning and memory. The findings are published online in the journal Proceedings of the National Academy of Science. http://www.physorg.com/news137776131.html Biology Tue, 12 Aug 2008 16:08:51 EST news137776131 St. Jude Children's Research Hospital scientists have identified one of the molecular mechanisms underlying the genetic brain malformation called holoprosencephaly (HPE). The findings not only yield insights into the most common developmental malformation of the anterior brain and face in newborns, but also help in understanding the intricate process by which the brain forms in the developing fetus. http://www.physorg.com/news137691061.html Medicine & Health Mon, 11 Aug 2008 16:31:01 EST news137691061
