These cells also function as an internal repair system, undergoing unlimited division to replace old and damaged cells in a living person or animal (Monroe, Miller, & Tobis, 2008).

These cells are unspecialized and have the potential to develop into other types of specialized cells like muscle, blood, brain, and other types of tissue cells during early life and during growth (Monroe et al., 2008).
