  • Stem cells numbers remain fixed because stem cells compete 'neutrally' for niche space (30). (hubrecht.eu)
  • Daughters of the small intestinal stem cells, the Paneth cells, serve as crypt niche cells by providing Wnt, Notch and EGF signals (33). (hubrecht.eu)
  • A key obstacle has been the lack of understanding about the microenvironment, or niche, in which blood-forming stem cells reside in the body. (utsw.edu)
  • The cells that glowed green were endothelial and perivascular cells, revealing them as the creators of the niche that nurtures healthy blood-forming stem cells. (utsw.edu)
