Embryonic stem cells,on the other hand, were discovered only in 1998,and it is believed by some researchers that they could help find treatment and cures for more than 70 serious diseases and injuries
Embryonic stem cells are blank,unspecialized cells found in a blastocyst. A blastocyst is a mass of 150 or so cells that develops approximately 5-14 days after an egg is fertilized. Embryonic stem cells make up the inner cells mas of the blastocyst. Embryonic stem cells are different from adult stem cells in that they are omnipotent, meaning they can grow into any and every cell except egg and sperm cells. Embryonic stem cells also have the agility to continue to multiply and exist indefinitely. Some scientists believe that the versatility of embryonic stem cells gives them a greater potential than that of adult stem cells
