stem cell

n.
An unspecialized cell that can give rise to one or more different types of specialized cells, such as blood cells and nerve cells. Stem cells are present in embryos and in various tissues of adult organisms and are widely used in scientific research.

stem cell

A cell that has the potential to develop into any of a number of different types of cells. Embryos have stem cells that can develop into almost any kind of body cell. Certain tissues in adults also produce stem cells, although the range of cells that they can develop into is limited.
