Bone marrow, brain, and liver.

- Bone marrow: source of hematopoietic and mesenchymal adult stem cells.
- Brain: contains neural stem/progenitor cells (e.g., subventricular zone, hippocampus).
- Liver: contains hepatic progenitor (oval) cells that act as adult liver stem/progenitor cells.

(Amniotic fluid and embryo provide fetal/embryonic-type stem cells; gametes are differentiated germ cells.)
