The fine structure of the gall bladder epithelium (mouse) has been investigated after fixation in four different solutions (OsO4-Palade, OsO4-Millonig, Glutaraldehyde and OsO4, Glutaraldehyde Formaldehyde and OsO4). Independent from fixation applied the following cells can be identified: 1. principal cells, 2. brush cells, 3. migrating cells, 4. granulated cells. The results show however that the “clear” and “dark” principal cells are to be considered as fixation artifacts. The renewal of the epithelium and the possible functions of the four cell types described are discussed.
