Doctors in Glasgow have injected stem cells into the brain of a stroke patient in an effort to find a new treatment for the condition.
Scientists who investigated a case of stem cell therapy to treat kidney disease are warning of a new type of complication not seen before, the development of blood vessel and bone marrow masses, the long term effects of which are unknown.
It has long been a given that adult humans — and mammals in general — lack the capacity to grow new nephrons, the kidney’s delicate blood filtering tubules, which has meant that dialysis, and ultimately kidney transplantation, is the only option for the more than 450,000 Americans who have kidney failure.
Johns Hopkins University researchers have demonstrated that human liver cells derived from adult cells coaxed into an embryonic state can engraft and begin regenerating liver tissue in mice with chronic liver damage.
Many scientists believe up to 40 percent of liver cancer is caused by stem cells gone wild – master cells in the organ that have lost all growth control. But, despite years spent looking, no one has ever found these liver “cancer stem cells” – or even normal stem cells in the organ. Until now.
Uncovering process that determines fate of stem cells may lead to better treatments for type 1 diabetes
By looking at markers on proteins known as histones, around which DNA molecules wind, a team of researchers from the University of Pennsylvania believes that it may be possible to predict the fate of embryonic stem cells. This knowledge could be used to steer these cells toward developing into insulin-producing pancreatic cells, which individuals with type 1 diabetes lack.
