Progenitor

Progenitor is a term used in various fields of science, including biology, astronomy, and medicine. In the context of medicine, a progenitor cell is a biological cell that, like a stem cell, has a tendency to differentiate into a specific type of cell. However, it is already more specific than a stem cell and is pushed to differentiate into its "target" cell. The most important difference between stem cells and progenitor cells is that stem cells can replicate indefinitely, whereas progenitor cells can divide only a limited number of times.

Biology

In the context of biology, progenitor cells are cells that have the capacity to differentiate into one or more types of cells. They are similar to, but not as versatile as, stem cells. Progenitor cells are found in adult organisms and they act as a repair system for the body, replenishing adult tissues.

Medicine

In medicine, progenitor cells are often used in the context of stem cell therapy. They have the potential to be used in a variety of medical treatments, including the treatment of cancer, heart disease, and neurodegenerative diseases.

Astronomy

In astronomy, a progenitor refers to the star that existed before a catastrophic event such as a supernova.
