title: Studies on the histogenesis of the tunica mucosa of the stomach of the Egyptian water buffalo (Bos bubalus L.). II. Histogenesis of the reticular mucosa.
abstract: In the fetus with 9 cm CRL the reticular mucosa was made up of a Lamina epithelialis and a Lamina Propria/submucosa. The primordia of the reticular crests firstly appeared in the fetus with 16 cm CRL as evaginations of the basal zone of the Lamina epithelialis into the superficial one. Invaginations from the luminal surface of the Lamina epithelialis above the tips of the long reticular crests were formed in the fetus with 27 cm CRL. Aggregations of smooth muscle cells appeared in the cores of the long reticular crests in the fetus with 50 cm CRL. In the fetus with 73 cm CRL invaginations of various depths were formed to separate the reticular crests from the mass of epithelium. The epithelium in the different fetal stages were missing a Stratum corneum.
