Team develops new method for producing precursor of neurons, bone, other important tissues from stem cells
In principle, stem cells offer scientists the opportunity to create specific cell types—such as nerve or heart cells—to replace tissues damaged by age or disease. In reality, coaxing stem cells to become the desired ...
