Stem Cells and Aging
Stem cells are undifferentiated cells that have the ability to transform into different cell types in the body. With age, the ability of stem cells to regenerate and differentiate into specialized cells declines, leading to a decrease in tissue repair and regeneration. Aging is also associated with changes in stem cell niches, which can affect their functionality and contribute to the aging process. Stem cell therapy has shown promise in treating age-related diseases and promoting tissue regeneration.
