text: Stem cells in animals and humans are primal undifferentiated cells that retain the ability to divide and differentiate into some, or all other, cell types. (The equivalent in higher plants are meristematic cells.) Stem cells have the potential to act as a repair system for the body, because they can divide and differentiate, replenishing other cells as long as the host organism is alive.\n\nFor more information about stem cell, u should visit:\nhttp://stemcells.nih.gov/
