The human brain and the brain of other mammals contain numerous populations of specialized cells with unique functions, molecular structures and characteristics. These cells originate from a thin layer of neuroepithelial ...
In a paper, "Epitope editing enables targeted immunotherapy of acute myeloid leukaemia," published in Nature, researchers at the Department of Pediatric Oncology, Dana-Farber Cancer Institute, Boston, introduce a genetic ...
Astrocytes are a type of glial cell in the central nervous system that clear excess neurotransmitters, promote the formation of synapses (i.e., connections between neurons), and perform other functions. The development of ...
Researchers at Stanford University in California have devised a fluorescence-activated cell-sorting method for isolating distinct neural stem and progenitor cell types from human brain tissue. The markers used in the study ...
Neuroregeneration entails not only neurogenesis, but also regrowth of lost connections and birth of non-neuronal cells. While adult neurogenesis in humans is only known to occur definitively in a few precisely circumscribed ...
An international team of researchers has found that the mouse cerebellum may not be a good model for the human cerebellum in brain studies. In their study published in the journal Science, the group describes their comparison ...
Nerve cells stripped of their insulation can no longer carry vital information, leading to the numbness, weakness and vision problems often associated with multiple sclerosis. A new study shows an overlooked source may be ...

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.
