Cellular Interactions in the Stem Cell Niche

Abstract
Stem cells are capable of both self-renewal and differentiation into many different cell types. These hallmark characteristics are regulated by other cells within the stem cell niche. In their Perspective, Wurmser et al. discuss the finding that endothelial cells in the neural stem cell niche secrete factors that influence neural stem cells to proliferate and become neurons ( Shen et al.).
