In adults, stem cells play a crucial role in tissue maintenance and repair. They are responsible for regenerating damaged or lost cells in various tissues, such as blood, skin, and muscle. Adult stem cells are typically multipotent, meaning they can differentiate into a limited range of cell types specific to their tissue of origin. This ability helps sustain the body's homeostasis and respond to injury or disease.

In adults, new surface epithelial cells and the epithelial cells lining the intestine are derived from stem cells located in the basal region of the epithelium. These stem cells continuously divide and differentiate to replace damaged or lost cells, maintaining the integrity and function of the tissue.
The three types of stem cells in adults are hematopoietic stem cells (found in bone marrow and produce blood cells), mesenchymal stem cells (found in various tissues like bone marrow and fat, can differentiate into bone, cartilage, and fat cells), and neural stem cells (found in the brain and spinal cord, can differentiate into neurons and supporting cells).
