RESUMO

The indirect immunofluorescence procedure was used to identify prolactin (LTH)-and somatotropin (STH)-producing cells in the pituitary of the Mexican axolotl. Histological staining techniques were employed to corroborate immunocytological results. The LTH cells are large, orange-staining cells (acidophils 1) distributed in the posterior two-thirds of the pars distalis. The STH cells are small, erythrosinophilic elements (acidophils 2) principally concentrated in the dorsal part of the pars distalis.
