[Immunohistochemical studies of intermediate filament type in the human hypophysis and in adenoma].

Abstract

The paper describes the value of immunohistologically estimated differences in the intermediate filament protein composition of the different cell types of human adenohypophysis and the corresponding pituitary adenomas. Interestingly, some tumors failed to express any type of intermediate filament proteins, whereas other coexpress cytokeratins and vimentin/or neurofilament protein.
