Stem cells, which have the potential to turn into any kind of cell, offer the tantalizing possibility of generating new tissues for organ replacements, stroke victims and patients of many other diseases. Now, scientists at the Salk Institute have uncovered details about stem cell growth that could help improve regenerative therapies. While previous studies have shown that two key cellular processes, called Wnt and Activin, … Continue reading Researchers have discovered a new pathway in stem cell differentiation.
