[Mammosomatotropic cells in the pituitary gland of the rat with and without adenoma. Immunoelectron microscopic study].

Abstract

In non-tumorous adenohypophysis and in adenomas of adenohypophysis of rats the GN and PRL producing bihormonal mammosomatotroph cells were demonstrated by double marked immune-gold immuno-electronmicroscopic examinations. Cytogenesis and regulation of these cells are known, their clearing up is expected. Further examinations are needed to elicit, whether mammosototroph cells may occur also in nontumorous human adenohypophysises.
