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 ). 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.

WebHome: Cell Press WebAug 6, 2024 · The adult central nervous system (CNS) contains resident stem cells within specific niches that maintain a self-renewal and proliferative capacity to generate new neurons, astrocytes, and oligodendrocytes throughout adulthood. Physiological aging is associated with a progressive loss of function and … 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. bis list lock
