Abstract

Discovered more than 15 years ago, endothelial progenitor cells attract both basic and translational researchers. It has become clear that they represent a heterogeneous population of endothelial colony-forming cells, early or late outgrowth endothelial cells, or blood outgrowth endothelial cells, each characterized by differing proliferative and regenerative capacity. Scattered within the vascular wall, these cells participate in angiogenesis and vasculogenesis and support regeneration of epithelial cells. There is growing evidence that this cell population is impaired during the course of chronic cardiovascular and kidney disease when it undergoes premature senescence and loss of specialized functions. Senescence-associated secretory products released by such cells can affect the neighboring cells and further exacerbate their regenerative capacity. For these reasons, adoptive transfer of endothelial progenitor cells is being used in more than 150 ongoing clinical trials of diverse cardiovascular diseases. Attempts to rejuvenate this cell population either ex vivo or in situ are emerging. The progress in this field is paramount to regenerate the injured kidney.
