Studies on the histogenesis of the tunica mucosa of the stomach of the Egyptian water buffalo (Bos bubalus L.). V. Histogenesis of the abomasal mucosa.
The primordia of the mucosal longitudinal folds are already prominent in the fetus with 9 cm CRL. In the fetus with 9 cm CRL the epithelium is stratified and becomes mixtured of simple and pseudostratified columnar in the fetus with 16 cm CRL in which the primordia of the abomasal glands are firstly seen but finally in the fetus with 17 cm CRL the whole epithelium becomes simple columnar. Although some few parietal cells are evident in the fetus with 73 cm among some fundic glands, but the complete-establishment of their cellular elements is completed postnatally. The Lamina muscularis mucosae is firstly seen in the fetus with 16 cm in the terminal portion of the abomasum.
