Organ systems studied in published research

Sources checked 2026-10-07 · 14 organ systems · 127 cited studies

This section groups the compounds covered on this site by the organs and tissues that published studies have looked at. Each entry names the model and the tissue that a published study looked at, with the citation. It describes what was studied, not what was found, and a listing here is not a claim that a compound does anything in that organ.
