Insulin, nutrition prevent blood stem cell differentiation in fruit flies
UCLA stem cell researchers have shown that insulin and nutrition keep blood stem cells from differentiating into mature blood cells in Drosophila, the common fruit fly, a finding that has implications for studying inflammatory ...

Bioengineers reprogram muscles to combat degeneration
Researchers at the University of California, Berkeley, have turned back the clock on mature muscle tissue, coaxing it back to an earlier stem cell stage to form new muscle. Moreover, they showed in mice that ...

Human-cell-derived model of ALS provides a new way to study the majority of cases
For decades, scientists have studied a laboratory mouse model that develops signs of the paralyzing disease amyotrophic lateral sclerosis (ALS) as they age. In a new study appearing in Nature Biotechnology, investigators at Nat ...

Adult stem cells carry their own baggage: Epigenetics guides stem cell fate
Adult stem cells and progenitor cells may not come with a clean genetic slate after all. That's because a new report in the FASEB Journal shows that adult stem or progenitor cells have their own unique "epigenetic signat ...

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.
