Adult stem cells are cells found in various tissues of the body that can self-renew and differentiate into specialised cell types. Unlike embryonic stem cells, adult stem cells are found in fully developed organisms and help maintain and repair the tissue where they are located, such as in blood, skin, or muscle. They are essential for the body’s natural healing processes and may be used in medical treatments to replace damaged cells. Understanding adult stem cells is important in GCSE Biology as it highlights the concepts of cell differentiation and the body's capacity to grow and repair itself.
