Question
Chapter 42.4, Problem 4CC
Summary Introduction
To explain: The differentiation of embryonic stem cell from stem cells present in the bone marrow of an adult.
Concept introduction:
Stem cells can reproduce indefinitely and divide mitotically to produce one daughter cell that remains as a stem cell and perform a specialized function. Embryonic stem cells are the pluripotent stem cells originating from the inner cell mass of the blastocyst.

- Why are stem cells not more abundant in the human body? I learned that stem cells can proliferate into any kind of cell in the body.

What are the benefits and risks of an increase of stem cells? Do the benefits outweigh the possible problems? Is an increase in stem cell numbers only worth while when an injury has occurred such as in stem cell therapy?
