Intriguingly, the age-related changes in Nestin-NSCs cell fate … 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.
