Adult stem cells are specialized cells found in various tissues of the body, such as bone marrow, skin, and muscle. They have the unique ability to self-renew and differentiate into different cell types, which helps in repairing and maintaining the tissues where they reside. Unlike embryonic stem cells, adult stem cells are more limited in their potential to become different cell types. These cells play a crucial role in healing and regeneration. For example, when you get a cut, adult stem cells in the skin can help produce new cells to close the wound. Researchers are studying adult stem cells for their potential in treating various diseases and injuries, making them an important area of medical research.
