-'''Stem cells''' have the remarkable potential to develop into many different cell types in the body.
+#REDIRECT [[stem cells]]
-When a stem cell divides, each new cell has the potential to either remain a stem cell or to become another type of [[cell]] with a more specialized function, such as a [[muscle]] cell, a [[red blood cell]], or a [[brain]] cell.
-Serving as a sort of repair system for the body, they can theoretically divide without limit to replenish other cells as long as the [[organism]] is still alive.
-*Broadly speaking, a stem cell is one that – in the course of [[cell division]] and increase in the numbers of cells – is able to reproduce itself and also mature into various specialized types of cells. The stem cell with the greatest potential (totipotential) is the fertilized [[egg cell]], which is capable of developing into a complete organism.
