Major discovery explains how adult brain cleans out dead brain cells, produces new ones
(Medical Xpress) -- Adult brains generate thousands of new brain cells called neurons each day; however only a small fraction of them survive. The rest die and are consumed by scavenger cells called phagocytes. Until now, ...

Study discovers that stem cell senescence drives aging
Declining levels of the protein BubR1 occur when both people and animals age, and contribute to cell senescence or deterioration, weight loss, muscle wasting and cataracts. Mayo Clinic researchers have shown that adult progenitor ...

Progenitor cell
Like stem cells, progenitor cells have a capacity to differentiate into a specific type of cell. In contrast to stem cells, however, they are already far more specific: they are pushed to differentiate into their "target" cell. The most important difference between stem cells and progenitor cells is that stem cells can replicate indefinitely, whereas progenitor cells can only divide a limited number of times. Controversy about the exact definition remains and the concept is still evolving.
Despite the difficulty of defining progenitors, the term is frequently used in research. Thus, the importance of progenitors cannot be ignored.
The terms "progenitor cell" and "stem cell" are sometimes equated.
