Abstract
The-low potential-difference (LPD) cells and the high-potential-difference (HPD) cells ofManduca sexta midgut epithelium have not previously been directly linked with the two major histological cell types, goblet and columnar cells. Using ionophoretic injection of fluorescent dye into LPD and HPD impalement types, we have located the dye-filled cells with the fluorescence microscope, and directly linked the goblet cell with the LPD impalement type and the columnar cell with the HPD impalement type. Thus, for the first time in this polymorphic tissue, the impalement type responsible for active ion transport, the LPD type, has been identified as the goblet cell.
