- First In Adult Stem Cell Research- Heart Derived Cells Develop Into Heart Muscle
Dutch researchers at University Medical Center Utrecht and the Hubrecht Institute have succeeded in growing large numbers of stem cells from adult human hearts into new heart muscle cells. Prior to this, it was necessary to use embryonic stem cells. Their ...
