Cellular Aging, Repair, and Stem Cells
Description
Cellular aging and tissue repair help explain how the body keeps its tissues working over time. Aging is the gradual loss of cell function. Regeneration is the repair of damaged tissue, and it is often mediated by preexisting adult, or somatic, stem cells.
Scientists study these processes to unde...

Transcript
Biologists in the field of aging and regeneration aim to understand the mechanisms of these two complex processes that are implicated in maintenance of tissue homeostasis.
Aging, or "senescence," involves deterioration of cell morphology and loss of functions over time, whereas regeneration refers to replacement of ...
