stem cell An unspecialized cell found in fetuses, embryos, and some adult body tissues that has the potential to develop into specialized cells or divide into other stem cells. Stem cells from fetuses or embryos can develop into any type of differentiated cells, while those found in mature tissues develop only into specific cells. Stem cells can potentially be used to replace tissue damaged or destroyed by disease or injury, but the use of embryonic stem cells for this purpose is controversial. Also called progenitor cell .
