Definitions for "Stem cells"
Immature cells that can develop into any type of cell, for instance, blood cells or tissue
These hematopoietic (blood-forming) cells are immature cells that can mature into blood cells -- the body's red blood cells, white blood cells and platelets. Stem cells either form more hematopoietic cells or white cells (infection fighting), red cells (oxygen carrying) or platelets (blood clotting cells.) Stem cells are found in the bone marrow and blood, and in a newborn’s umbilical cord.
