Meaning and Definition
The state or condition in which cells or tissues from one organism can survive and be accepted by the immune system of another organism without being rejected.
In immunology and medicine, it refers specifically to the compatibility of tissues from different individuals, determined by genetically encoded molecules (especially Major Histocompatibility Complex/MHC molecules). A match is required for successful organ or tissue transplants.

- Misspelling as 'histocompatability' (wrong vowel).
- Using it as an adjective (e.g., 'histocompatible' is the correct adjective form).
- Confusing it with general 'compatibility' in non-biological contexts.
FAQ
Frequently Asked Questions
The MHC is a large gene family found in most vertebrates that encodes proteins essential for the acquired immune system. These proteins present antigens to T-cells and are the primary determinants of histocompatibility.
While most critical for transplants, histocompatibility is also a fundamental concept in immunology, explaining how the immune system distinguishes 'self' from 'non-self'. It's relevant in autoimmune diseases, pregnancy, and cancer immunology.
Yes, but it is statistically unlikely to have a perfect match. Siblings have a 25% chance of being a perfect match. Unrelated donors are found through large international registries where a close, but rarely perfect, match is sought.
The direct opposite is 'histoincompatibility'. In clinical practice, the result is 'tissue rejection' or 'graft rejection'.
The state or condition in which cells or tissues from one organism can survive and be accepted by the immune system of another organism without being rejected.
Histocompatibility is usually technical/scientific in register.
Histocompatibility: in British English it is pronounced /ˌhɪstəʊkəmˌpætəˈbɪləti/, and in American English it is pronounced /ˌhɪstoʊkəmˌpætəˈbɪləti/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think: "HISTO-" (tissue) + "COMPATIBILITY" (ability to get along). 'Tissue compatibility' for transplants.
Conceptual Metaphor
A LOCK AND KEY METAPHOR: Histocompatibility molecules are like unique 'locks' on cells; the immune system has 'keys'. A match means the donor 'key' fits the recipient's 'lock' without triggering an alarm.
