title: Studies on cell migration, adenylate cyclase and membrane-coating granules in the buccal epithelium of the zinc-deficient rabbit, including the influence of isoproterenol.
abstract: Cell migration was slightly increased; cytochemical reaction deposits of adenylate cyclase and the area density of membrane-coating granules (MCG) were significantly increased. Upon isoproterenol stimulation, the MCG area density was significantly increased, whereas the cell migration rate was unchanged. Thus in zinc deficiency, there may be a simultaneous increase in the production and secretion of MCGs, in adenylate cyclase activity, and in cell migration. The non-significantly increased cell migration rate may not keep pace with the significantly increased cell-production rate, resulting in thickening of the epithelium.
