First Evidence of a Pan-tissue Decline in Stemness During Human Aging
Aging is still shrouded in proverbial darkness. But, some researchers hypothesize that aging may be linked to stem cell exhaustion. Stemness, the ability of a cell to differentiate into various cell types, is an essential characteristic defining the functionality of stem cells. It has been observed that stem cells seem to diminish with age, although the precise role of stem cells in human aging remains to be elucidated. “Among the biological pathways associated with aging, we can highlight stem cell exhaustion, which argues that during normal aging, the decrease in the number or activity of…
