Ontogeny, distributions and relative frequencies of somatostatin-immunoreactive cells were investigated in the proventriculus of the chicken embryos with incubation periods. Samples were taken from 10 groups(10 days of incubation to hatching) and studied by immunogistochemical methods. The findings were as follows. Somatostatin-immunoreactive cells were observed from 12 days of incubation in the proventricular glands and after that increased with incubation periods. The first observation time of these cells in the epithelium were at 15 days of incubation in the basal portion but in 16 and 17 days of incubation, no immunoreactive cells were observed in the epithelium but after that a few immunoreactive cells were observed in the basal portion and gastric gland regions. The shpaes of these cells were spherical to spindle in the proventricular glands and spherical to round in the epithlium and gastric gland.
