Stem cells are unspecified cells that are pluripotent, meaning they have the potential to develop into many different cell types in the body. In many tissues, they serve as an internal repair system, dividing essentially without limit to replenish other cells. When stem cells divide, each new cell has the potential to become another type of cell with a more specialized function, such as muscle cells, blood cells, or skin cells. Human amniotic fluid derived stem cells have the potential to be used for important therapies for different diseases, conditions and areas of medical need. Unlike other forms of stem cells, they do not require laboratory manipulation to express these qualities.
