p21 Cip1 Levels Differentially Regulate Turnover of Mature Endothelial Cells, Endothelial Progenitor Cells, and In Vivo Neovascularization

Abstract
P21Cip1 (p21) controls cell cycle progression and apoptosis in mature endothelial cells (ECs) and regulates size and cycling of the hematopoietic progenitor cell pool. Because circulating endotheli...
