Fusion and cell death in the development of skeletal muscle
(Medical Xpress)—Membrane fusion is a highly regulated event, both inside cells, and between them. From the moment a sperm first fuses with an egg, subsequent developmental events depend upon its proper ...

Natural process activating brain's immune cells could point way to repairing damaged brain tissue
The brain's key "breeder" cells, it turns out, do more than that. They secrete substances that boost the numbers and strength of critical brain-based immune cells believed to play a vital role in brain health. This finding ...

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.
