Adult Stem Cells 101

What are Progenitor Cells?

Often confused with adult stem cells, progenitor cells are early descendants of stem cells that can differentiate to form one or more kinds of cells, but cannot divide and reproduce indefinitely. A progenitor cell
is often more limited than a stem cell in the kinds of cells it can become. Nonetheless, progenitor cells do have potential uses in medicine. Boston Children’s Hospital researchers, for example, are studying the potential of blood and muscle progenitor cells in building heart valves, as well as blood vessels and electrically conductive tissue for the heart.
