http://pressbooks-dev.oer.hawaii.edu/anatomyandphysiology/chapter/cellular-differentiation/ WebStem cells have the ability to self-renew. Unlike muscle cells, blood cells, or nerve cells—which do not normally replicate— stem cells may replicate many times. When a stem cell divides, the resulting two daughter cells may be: 1) both stem cells, 2) a stem cell and a more differentiated cell, or 3) both more differentiated cells. peak performance w frost down jacket
