Abstract
This immunocytochemical study of the pituitaries of the primitive actinopterygians, Acipenser transmontanus, Lepisosteus spatula, and Amia calva, showed a strict delineation between the hormonal fragments of proopiomelanocorticotropin (POMC) produced by corticotropes of the pars distalis and the melanotropes of the pars intermedia. Corticotropes were immunoreactive only for ACTH and not to either of the further degradation products, alpha-MSH or beta-endorphin. Melanotropes were shown to be immunoreactive to all three antisera but it is argued that immunoreactivity of melanotropes to ACTH antiserum is due to that antiserum's cross-reactivity with the cleavage product corticotropin-like intermediate peptide. The PAS positivity of both the corticotropes and the melanotropes of all three primitive fish argues for an ancient origin of a carbohydrate component of POMC and for its loss or reduction in teleosts where these cells are PAS negative.
