Stem cells are populations of cells with the potential to develop into many different types of cells, tissues, and organs. Stem cells are characterized by their capacities of multipotency to differentiate or self-renew. They play a crucial role in many aspects of biology, from embryo development to tissue repair and maintenance. In many organs and tissues, they serve as an internal system for regeneration and repair. Stem cells divide essentially without limit to maintain the stem cell pool and replenish other cells as long as needed. |
