Potential cell source.
| Source | Definition | Drawbacks | Donor/recipient |
| Autologous | Same individual | Not always available (genetic diseases, age) | Allogenic | Same species | Immunological issues | Xenogenic | Different species | Ethical issues and rejection | Syngenic or isogenic | Genetically identical individuals (clones, inbred) | Most appropriate for research with animal model |
| Origin/differentiation |
| Primary | Tissue or organ/specialized | Large expansion needed | Secondary | Cell bank | Cryopreservation/immunological issues | Embryonic stem cells (iPSCs) | Undifferentiated | Ethical issues/purification/teratoma | Adult stem cells | Commited | Selection of type/source |
