Histological changes, distributions and relative frequencies of bovine Sp-1/chromogranin (bCG)-, serotonin-, gastrin-, cholecystokinin-8(CCK-8)-, somatostatin-, S-100 protein-, polypeptide YY(PYY)- and glucagon-immunoreactive cells were investigated in the gizzard and pylorus of the chicken embryos from 10 days of incubation to hatching. Histologically, the pseudostratified columnar epithelium were observed from 10 days of incubation to 15 days of incubation, thereafter these epithelium were differentiated to simple columnar epithelium, gastric gland and/or mucosal gland. In the gizzard, bCG-immunoreactive cells were observed from 19 days of incubation and S-100 protein-immunoreactive cells were detected from 15 days of incubation to 18 days of incubation. No serotonin-, gastrin-, CCK-8-, somatostatin-, PYY- and glucagon-immunoreactive cells were found in this region. In the pylorus, bCG-, gastrin- and somatostatin-immunoreactive cells were observed from 16 days of incubation respectively, thereafter these cells were increased with ages. CCK-8-immunoreactive cells were detected on hatching and S-100 protein-immunoreactive cells were detected from 16 days of incubation to 18 days of incubation. No serotonin-, PYY- and glucagon-immunoreactive cells were observed in this region.
