Histochemical methods for the further characterisation of the tumourettes of the posterior lobe of the pituitary.
The granular cell tumourettes of the posterior lobe of the pituitary possess neuraminic acid containing carbohydrate. After removal of neuraminic acid with neuraminidase and exposure to FITC (Fluorescein isothiocyanate) labelled peanut agglutinin (Arachis hypogaea) (PNA), intracellular receptor structures could be demonstrated. The significance of the findings is discussed.
