| Abstract |
|
Histological changes and ontogeny, distribution and relative frequency of bovine SP-1/chromogranin(BCG)-, serotonin-, human pancreatic polypeptide(HPP)- and glucagon-immunoreactive cells were investigated in the colo-rectum of the chicken embryos. The pseudostratified columnar-like epithelium was observed in 10 days of incubation to 15 days of incubation, thereafter these epithelium were differentiated to simple columnar epithelium and goblet cells were detected for the first time on 19 days of incubation. BCG and serotonin-immunoreactive cells were observed for the first time on 15 days of incubation respectively, thereafter these cells were increased with ages. However no HPP and glucagon-immunoreactive cells were found in this study. |
