![]() We lose over 20 billion cells a day, requiring constant replenishment to stay alive. Even though the intrinsic properties of stem cells are likely to be similar across tissues, each tissue has its own requisites for homeostasis and regeneration. Some tissues of the body, such as those in the brain and skeletal muscle, have very little turnover and are well protected, whereas others turnover constantly. Given the importance of stem cells to body tissues, it has long been postulated that stem cells should be used sparingly and tucked safely away into resident niches, guarding them from harm’s way. These remarkable fixtures of longevity place stem cells in an elite class of essential cells of living organisms. ![]() Adult stem cells have the capacity to self-renew and to regenerate tissue(s) long-term, in both homeostasis and wound repair.
