Stem cells are the raw material of the organism: cells from which all other cells of the organism are generated. Under the right conditions, in the body or in the laboratory, divide to form more cells called daughter cells.
These daughter cells become new stem cells (self-renewal) or specialized cells (differentiation) or into specialized cells (differentiation) with a more specific function, such as blood, brain, heart muscle or bone cells. No other cell in the body has the natural ability to generate new cell types.
