The use of H&E and performic acid combined with alcian blue ph. 2.5 for the histological identification of endocrine cells. A and B are the results of H&E staining on a paraffin section of the fundic stomach. The epithelium (e), lamina propria (lp), and gastric gland interstitial cells (gl) are all sites of endocrine cells. The red arrow indicates a binucleated endocrine cell. (B) Performic acid staining of endocrine cells is positive. The epithelium and the stomach gland (gl) are where you can find them
