USE OF STEM CELL:
The first attempts to turn mature cells back into pluripotent stem cells involved a process called cloning. In the cloning process, an egg is fertilized in the lab, and right after fertilization, the DNA is removed from the egg.These stem cells come from embryos that are three to five days old. These are pluripotent (ploo-RIP-uh-tunt) stem cells, meaning they can divide into more stem cells or can become any type of cell in the body. This versatility allows embryonic stem cells to be used to regenerate or repair diseased tissue and organs.Despite the potential benefit of using human ES cells in the treatment of disease, their use remains controversial because of their derivation from early embryos.Learn more:
