Abnormal Cell Cycle: Cancer Section 3 Cellular Reproduction Cell Cycle Regulation Abnormal Cell Cycle: Cancer Cancer is the uncontrolled growth and division of cells. Cancer cells can kill an organism by crowding out normal cells, resulting in the loss of tissue function.

Section 3 Cellular Reproduction Cell Cycle Regulation Causes of Cancer The changes that occur in the regulation of cell growth and division of cancer cells are due to mutations. Various environmental factors can affect the occurrence of cancer cells.

Section 3 Cellular Reproduction Cell Cycle Regulation Stem Cells Unspecialized cells that can develop into specialized cells when under the right conditions

Section 3 Cellular Reproduction Cell Cycle Regulation Embryonic Stem Cells After fertilization, the resulting mass of cells divides repeatedly until there are about 100–150 cells. These cells have not become specialized.

Section 3 Cellular Reproduction Cell Cycle Regulation Adult Stem Cells Found in various tissues in the body and might be used to maintain and repair the same kind of tissue Less controversial because the adult stem cells can be obtained with the consent of their donor
