Scientists report first step in strategy for cell replacement therapy in Parkinson's disease
Induced pluripotent stem cells (iPSC) are a promising avenue for cell replacement therapy in neurologic diseases. For example, mouse and human iPSCs have been used to generate dopaminergic (DA) neurons that improve symptoms ...

'Back talk' from blood cells to their progenitors is critical to balancing blood supply
(PhysOrg.com) -- When it comes to the body's blood supply, maintaining the right balance is crucial. UCLA stem cell scientists have now discovered that in the common fruit fly, this balancing act requires a complex "conversation" ...

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, ...

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.
