| Activation | Mechanism | Target Cell/Organ | Cancer |
|---|---|---|---|
| Examples are provided of stem cell activation by different mechanisms. For each type there are several known examples, but only a single example is shown. | |||
| None | Naturally activated stem cell | Retinoblast | Retinoblastoma |
| Inflammation | Activates cell growth | Colon | Colon cancer |
| Viral infection | Stimulates immune response | Liver | Hepatocellular carcinoma |
| Hormones | Stimulates cell growth | Breast | Breast cancer |
| Bacterial infection | Inflammation | Stomach | Gastric cancer |
