Stem cells' 'suspended' state preserved by key step, scientists report
Scientists have identified a gene that is essential for embryonic stem cells to maintain their all-purpose, pluripotent state. Exploiting the finding may lead to a greater understanding of how cells acquire their specialized ...

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 ...

Cells derived from pluripotent stem cells are developmentally immature
Stem cell researchers at UCLA have discovered that three types of cells derived from human embryonic stem cells and induced pluripotent stem cells are similar to each other, but are much more developmentally immature than ...

Coaxing new hair: Scientists work on perking up dormant follicles
When a man's hair stops growing back, it would be logical to assume his scalp has suffered a loss of stem cells, those versatile dynamos that have the ability to regenerate hair, blood, and other parts of the body.

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.
