When the sperm fertilizes the egg the first creation is a stem cell. It then divides into more stem cells which continue to divide until they begin to differentiate (or change), becoming specific types of cells that will go on to form all of the different parts of the body. These are the embryonic stem cells that are the focus of the media’s attention. But after birth, and throughout life, stem cells continue to be made in the body. And as science has recently discovered, these adult stem cells are the body’s primary system of renewal and restoration.
Watch this video on human development …… it shows the power of stem cells in developing an embryo into a full grown baby.
