...and contains adult stem cells which are capable of regenerating the entire system. The intuitive leap was to transplant cells obtained from this area into the injured spinal cord. What we found was that in laboratory animals the cells have a remarkable capacity to integrate into the damaged roadway, open up the...

Chemical turns stem cells into neurons say scientists at Scripps Research Institute

...urons in the brain are lost, may be ameliorated by regenerating neurons. Another example is Type 1 diabetes, an autoimmune condition in which pancreatic islet cells are destroyed by the body's immune system. Because stem cells have the power to differentiate into islet cells, stem cell therapy could potentially c...

UNC among 10 U.S. medical centers tapped to study living donor liver transplants

We are also proposing studies on short- and long-term outcomes for donors following donation surgery for living donor liver transplantation," Shrestha said. UNC began its live donor liver transplant program in October...

New horizons of nerve repair

... that cleaves the growth factor at just the time a regenerating nerve cell would be migrating through the matrix. This cell-activated drug delivery system is also incorporated into a gel and delivered from a nerve guide tube, and it's a great example of a new area known as biologically responsible materials.

Study identifies new drug target for preserving brain cells

...tissue. "The macrophage reaction is a good one in regenerating tissues, but in a non-regenerating tissue like the brain, it can be devastating," Levison said. When macrophages release IL-1 and attract more of the scavenger cells to the brain, they become exited and overactive, causing harm to other cells nearby...
