Growing Limbs with Stem Cells

Posted by on Jul 13, 2015 3:00:00 PM

Researchers at Mass General Hospital have built a rat forelimb with functional muscular and
vascular tissue using progenitor stem cells. The approach may be useful in developing
replacement limbs for transplantation in primates. The team, led by Dr. Harald Ott, injected
muscle progenitor cells into a cell-free matrix that preserved nerves and primary vasculature;
two weeks later, analysis confirmed the presence of blood vessel walls within vascular cells and
aligned muscle cells within the muscle matrix.
