Adult stem cell - Wikipedia, the free encyclopedia Adult stem cells are undifferentiated cells, found throughout the body after development, that multiply by cell division to replenish dying cells and regenerate damaged tissues. Also known as somatic stem cells (from Greek Σωματικóς, meaning of the body),
Stem cell niche - Wikipedia, the free encyclopedia Stem cell niche refers to a microenvironment where stem cells are found, which interacts with stem cells to regulate cell fate. The word 'niche' can be in reference to the in vivo or in vitro stem cell microenvironment. During embryonic development, vario

The Bone Marrow Microenvironment as Niche Retreats for Hematopoietic and Leukemic Stem Cells Figure 1: Organization of normal hematopoietic stem cell (HSC) and leukemic stem cell (LSC) niches in the bone marrow. Both HSCs and LSCs establish niches around the bone marrow endosteum and sinusoids. In normal hematopoiesis, the endosteal niche is ...
Stem cell dynamics in homeostasis and cancer of the intestine : Nature Reviews Cancer : Nature Publi Intestinal stem cells (ISCs) and colorectal cancer (CRC) biology are tightly linked in many aspects. It is generally thought that ISCs are the cells of origin for a large proportion of CRCs and crucial ISC-associated signalling pathways are often affected
Emerging interactions between skin stem cells and their niches : Nature Medicine : Nature Publishing (a) HFSCs can exist in two states. Quiescent bulge stem cells (Bu-SCs) are located in the outer layer of this niche and contribute to the generation of the outer root sheath. Primed stem cells reside in the hair germ, sandwiched between the bulge and a sp
Germline stem cell niches | StemBook (A). The Distal tip cell (DTC, green) functions as a niche to maintain GSCs (red, green shade representing the niche influence), allowing germ cells (pink) outside the influence of the niche to differentiate. (B). Wnt signaling controls the niche formatio
Adipocyte lineage cells contribute to the skin stem cell niche to drive hair cycling Introduction Tissue niches are essential for controlling stem cell self-renewal and differentiation (Voog and Jones, 2010). Epithelial lineages in the skin are maintained by stem cells that exist in multiple tissue microenvironments (Blanpain and Fuchs, 2
Lineage analysis of stem cells | StemBook In this hypothetical tissue, four stem cells (highlighted in dark blue at the beginning of the movie) are maintained in a niche (blue gradient highlighted in light blue at the beginning of the movie) produced by a population of non-dividing niche-generati
