The First Creation of Life
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.
What is Stem Cell ?
The National Institutes of Health defines a stem cell in this
"Stem cells have the remarkable potential to develop into many different
cell types in the body. Serving as a sort of repair system for the body, they
can theoretically divide without limit to replenish other cells as long as the
person is still alive. When a stem cell divides, each new cell has the potential
to either remain a stem cell or become another type of cell with a more
function, such as a muscle cell, a red blood cell, or a brain cell".
