[Coexistence of reactive and nonreactive endocrine cells in the fundal mucosa in the rabbit]

Whether the same endocrine like cells are reactive towards different staining methods has been examined in normal and L-Dopa treated rabbits for distinction of cell types. Correlation with electron microscopy is proposed. It seems likely that SM cells (poorly reactive with Sevier-Munger technic) include two cell types: cells having around medium size and dense granules; cells having small round dense granules (D1?). X cells may correspond to a well defined group at the electron or photonic microscopic level. Insertion of D cells (according to Solcia and coworkers nomenclature) is not satisfactory but true non Apud cells are described. The signification of Jt (dim yellow) cells remains unknown.
