- 2.3: Stem Cells
- Stem cells are cells that divide by mitosis to form either two stem cells, thus increasing the size of the stem cell "pool", or one daughter that goes on to differentiate, and one daughter that retains its stem-cell properties. How the choice is made is still unknown. However, several genes have been found whose activity prevents a daughter cell from differentiating.
- 2.4: Regeneration
- Regeneration is the ability to replace lost or damaged body parts. This ability varies greatly among living things.
