Stem cells make new heart valves

Summary;

Researchers have coaxed adult stem cells into forming artificial heart valves that could one day mean fewer surgeries for children suffering from heart defects. The scientists, at Harvard-affiliated Boston Children’s Hospital, grew the valves from a type of stem cell that normally gives rise to the inner lining of blood vessels. They used a biodegradable scaffold to give the cells shape and a mix of proteins and growth factors to stimulate the cells to grow into the proper tissue type.
