WebApr 11, 2024 · To maintain homeostasis, many tissues contain stem cells that can self-renew and differentiate. Based on these functions, stem cells can reconstitute the tissue even after injury. In reproductive organs, testes have spermatogonial stem cells that generate sperm in men throughout their lifetime. However, in the ovary, oocytes enter … WebIn addition, normal adult stem cells (ASCs) self-renew, proliferate infinitely, have a multidirectional differentiation potential, similar to that of tumor cells, and can transform more easily into tumor stem cells than non-stem cells [20, 21]. Consequently, ASCs are considered the origin of cancer, rather than normal mature tissue cells.

WebOct 18, 2024 · Recent studies show that quiescent stem cells are particularly vulnerable to aging-related damage. In the aging brain, deepened quiescence causes a long-term imbalance of NSC homeostasis that compromises stem cell maintenance and regenerative capacity ( Ibrayeva et al., 2024 ; Kalamakis et al., 2024 ). WebWith aging, the number of stem cells declines significantly in some cases. 90,91 For example, depletion of melanocyte stem cells in the hair follicles and the appearance of mature pigmented melanocytes in the stem cell niche have been reported in both aged mice and humans, 92,93 leading to one of the most visible phenotypic changes during …
