Abstrakt: Hormone assays of the rostral and caudal zone of the pars anterior of the wallaby pituitary showed a high concentration of prolactin and thyrotrophin in the rostral zone, and a high concentration of somatotrophin in the caudal zone. Gonadotrophin and corticotrophin were distributed throughout the whole gland. The distribution found shows that prolactin and somatotrophin are formed by different cells. Correlation with observable cell types suggests that prolactin may be formed by an acidophil cell with an affinity for acid fuchsin, and somatotrophin by an acidophil cell with an affinity for orange G. These identifications require confirmation from functional studies. [ABSTRACT FROM AUTHOR]
