What Are Stem Cells?

Stem cells are undifferentiated cells that are capable of giving rise to indefinitely more cells of any type. They are the “building blocks” of the body. They have the remarkable potential to develop into many different cell types in the body and serve as what can be accurately described as an “internal repair system,” replenishing other cells. Each divided cell has the potential to become another type of cell with a specialized function, such as a muscle cell, a red blood cell, or a brain cell.
