Stem cell therapy.

Ibrahim KI

What are stem cells? Stem cells are no differentiated cells that have the ability of proliferation, regeneration, conversion to differentiated cells and tissue production. Regeneration means that these cells have the ability of asymmetric division which one of the resulting cells remains as stem cell while another cell, which is called daughter cell, becomes one cell of germ layer. Stem cells may remain inactive for a long time till they enter cell division again
