This is the definition of a stem cell: an undifferentiated cell of a multicellular organism that is capable of giving rise to indefinitely more cells of the same type, and from which certain other kinds of cell arise by differentiation.

A stem cell can be used to help repair and re-generate damaged or lost tissue. Stem cells can be anything they want pretty much. It's a like a little kid who doesn't know what they wanna be when they grow up.
