Gall bladder: mucosa
Simple columnar epithelium lines the surface of the gall bladder. Cell nuclei tend to be basally located and the apical surface possesses numerous, short microvilli. The lamina propria, located beneath the epithelium, is quite cellular, including cells of the lymphoid series. 400x
