Among differences were a staining of ZNT2 along the lateral and apical membrane, a luminal border staining of ZNT4, a strong expression of ZNT5 resembling the staining of the Golgi complex (a cell structure to process and package the macromolecules such as proteins and lipids that are synthesized by the cell) in the ventral lobe, a relatively uniform expression in the amount of ZNT6 across the lob
