In this study, 20 female and 4 male adult New Zealand rabbits and their fetuses and newborns were used. Tissue samples were taken from fundus of stomach observed in the electron microscope. In electron microscope, cytoplasm of epithelial cells were poor in organels at the 19th day of pregnancy. The cells were determined to begin to differentiate at the 21st day of fetal period. In the surface epithelial cells and the neck mucous cells, a few secretory granules and intercellular secretory ducts in the parietal cells were seen at the 25th day of pregnancy. At the 1st day of postnatal period, principal cells were distinguished with respect to their organels. Afterwards, secretory granules in the surface of mucous cells and the neck of mucous cells, the number of mitocondria in the parietal cells increased and ribosomal endoplasmic reticulum in the principal cells developed and the cells almost fully gained their mature structure at the 20th day of postpartum.
