Stem cells. Conceptual computer artwork of a bundle of stem cells in culture. A stem cell is an undifferentiated cell that can divide indefinitely in culture. It can differentiate to form specialized cells that have a particular function, for example red blood cells, or it can develop to produce all the cells within an organ. Stem cells, in particular those derived from foetal tissue, are used in genetic research.
