Mending a broken heart: How to boost the number and function of cardiac stem cells

A current hope is that cardiac stem cells could one day be manipulated to rebuild cardiac tissue damaged by heart disease. In a study appearing online on June 21 in advance of publication in the July print issue of the Journal of Clinical Investigation, Edward Morrisey and colleagues from the University of Pennsylvania address a fundamental question in the cardiac stem cell field what are the molecular pathways required for expansion and development of cardiac stem cells"

The authors have delineated a novel and essential pathway for the expansion of recently identified islet (Isl-1)positive cardiac progenitor cells. These cells help form the right ventricle and outflow tract of the developing heart. The authors show that Wnt signaling through activation of fibroblast growth factor 10 (FGF10) expression was required for expansion of Isl-1 cardiac progenitors in the anterior heart; loss of Wnt signaling lead to a l
