Treatment Spurs Cell Division (image) University of Illinois at Urbana-Champaign Caption After injecting dystrophin-deficient mouse hearts with normal, blood-vessel-derived stem cells, researchers saw an increase in cell division among nestin-positive stem cells (shown in green) in the heart. These stem cells are found in the hearts of adult humans, rats, and mice, but their function is not yet known. An increase in formation of new heart muscle cells from the nestin-positive stem cells was also detected.
