Cell types of the pars distalis of the hedgehog (Erinaceus europaeus L.) adenohypophysis: cytological, immunocytochemical and ultrastructural studies. 3. Opiocorticomelanotropic cells.

Staining and histochemical methods, immunofluorescence and electron microscopy were used to individualize the opiocorticomelanotropic cells in the adenohypophysis of the non-hibernating hedgehog. One cell type was differentiated; its characteristics at the electron-microscopic level were presented. Immunofluorescence has confirmed the functional significance of this cell type and the validity of the denomination 'opiocorticomelanotropic cells'.
