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 ), they can be found in juvenile, adult animals, and humans, unlike embryonic stem ...
Mar 23, 2024 · Get answers about where stem cells come from, why they're important for understanding and treating disease, and how they are used.
Adult stem cells are located in specialized vascular microenvironments, referred to as the stem cell niche. The niche provides intrinsic and extrinsic signals that regulate cell fate and renewal and may explain why adult stem cells, isolated from various tissues, behave differently. The first adult stem cells were identified in the bone marrow ...
Jun 25, 2024 · Stem cell - Regeneration, Differentiation, Tissue Repair: Some tissues in the adult body, such as the epidermis of the skin, the lining of the small intestine, and bone marrow, undergo continuous cellular turnover. They contain stem cells, which persist indefinitely, and a much larger number of “transit amplifying cells,” which arise from the stem cells and divide a finite number of times ...
Throughout the life of the organism, populations of adult stem cells serve as an internal repair system that generates replacements for cells that are lost through normal wear and tear, injury, or disease. Adult stem cells have been identified in many organs and tissues and are generally associated with specific anatomical locations. These stem cells may remain quiescent (non-dividing) for ...
