Introduction Stem cells are immature cells which are mostly found in multi-cellular organism and they are mainly characterized by their ability to renew through mitotic cell division which later differentiates into ranges of various specialized cell types (James, 2004, p39). Stem cells in mammals are classified into two broad classed...
Abstract Evolution refers to the change of properties of a living organism from one generation to the next over a period of time.
