WebOct 19, 2024 · In some parts of the body, such as the gut and bone marrow, stem cells regularly divide to produce new body tissues for maintenance and repair. Stem cells are present inside different types of ... 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.
