'''Stem | '''Stem cell exhaustion''' is one of the [[Hallmarks of Aging|hallmarks of aging]], characterized by the decline in the quantity and quality of stem cells in the body. Stem cells are undifferentiated cells with the potential to differentiate into various types of cells and are essential for tissue regeneration and repair. As organisms age, stem cells gradually lose their regenerative capacity, leading to impaired tissue maintenance and increased vulnerability to diseases. | ||

Stem cells are responsible for replenishing and repairing tissues throughout an organism's life. They reside in specific areas known as stem cell niches and can divide asymmetrically to produce one daughter cell that retains stem cell properties and another that differentiates into a specific tissue cell. This process is crucial for the continuous renewal of tissues, such as skin, blood, and intestinal lining. | Stem cells are responsible for replenishing and repairing tissues throughout an organism's life.
