April 19, 2016 At a Glance A study in mice suggests that scar formation may help, not hinder, nerve regrowth after spinal cord injury. The findings, which contradict previous dogma, could lead to new strategies to encourage nerve fibers to regrow across spinal lesions. Previously injured axons (red) can grow through a dense astrocyte scar
February 16, 2015 By Michael C. Purdy ROBERT BOSTON Studying mice, Herbert W. Virgin, MD, PhD (left), and Thad Stappenbeck, MD, PhD, have shown that mothers can pass a trait to their offspring through the DNA of bacteria. The finding suggests that microbes may play a significant role in how genes influence illness and health in
National Institutes of Health - Nature, November 24, 2013, Dr. Richard Youle, NINDS investigator, a leader of the study NIH study sheds light on treatment of related disorders Scientists at the National Institutes of Health have used RNA interference (RNAi) technology to reveal dozens of genes which may represent new therapeutic targets for treating Parkinson’s disease.
Descendants of Henrietta Lacks endorse controlled access to cell line genome after meetings with Francis Collins. By Ewen Callaway 07 August 2013 Francis Collins, who heads the US National Institutes of Health, reached an agreement with the Lacks family about publication of the HeLa cell genome. This week a policy allowing controlled access to the
Jul 17 2013 Genomic imprinting maintains a reserve pool of blood-forming stem cells in mouse bone marrow KANSAS CITY, MO—Hematopoietic stem cells—bone marrow-derived adult stem cells that give rise to the wide variety of specialized blood cells—come in two flavors: the reserve force sits quietly waiting to be called upon while the active arm continually
ScienceDaily, by Staff ~ June 12, 2013 Mammals possess the remarkable ability to regenerate a lost fingertip, including the nail, nerves and even bone. In humans, an amputated fingertip can sprout back in as little as two months, a phenomenon that has remained poorly understood until now. In a paper published today in the journal

In mice bone marrow, blood stem cells, highlighted in blue, are nurtured by support cells shown in red and yellow. Image courtesy of Dan Link, MD. In research that could
Feb. 24, 2013 — Science Daily - In research that could one day improve the success of stem cell transplants and chemotherapy, scientists have found that distinct niches exist in bone marrow to nurture different types of blood stem cells. Distinct niches exist in bone marrow to nurture different types of blood stem cells, new
