'''Stem cells''' have the remarkable potential to develop into many different cell types in the body. 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. When a stem cell divides, each new cell has the potential to either remain a stem cell or become another type of cell with a more specialized function, such as a muscle cell, a red blood cell, or a brain cell.

*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.
