Unformatted text preview: May spread through the body by Metastasis Carcinogens are any item that may cause cancer. Normal cells go through apoptosis to prevent cancer. All animal cells can enter apoptosis. Humans have cells that naturally go through apoptosis as they develop. Plants have certain cells that go through apoptosis (leaves falling). Cell Cycle Regulation.notebook February 23, 2011 Two types of stem cells: Embryonic from the embryo during development Adult from certain tissues in the body Stem cells can become any type of cell. Researchers have formed nerve cells, brain tissue, pancreases, kidneys, livers, ears, etc. with stem cells....
