Abstract
Ultrastructural localization of vasoactive
intestinal polypeptide (VIP) was studied in the chicken
pancreas by the immunocytochemical method. VIPimmunoreactive
nerve endings were found in contact
with acinar cells in the pericapillary space or between
acinar cells. They also terminated on epithelial cells of
arteriolae. In pancreatic islets, VIP-immunoreactive
nerve endings were in contact with B-cells, but not with
A- or D-cells. VIP-imrnunoreactive terminals contained
many small clear vesicles which indicate the cholinergic
feature. Nerve endings containing many small clear
vesicles but not showing VIP-immunoreactivity were
also detected in both the exocrine and endocrine
pancreas. According to these data and the previous
studies concerning the cholinergic and VIPergic
innervation of the chicken pancreas, it is suggested that
VIP-containing cholinergic nerves innervate B-cells and
cholinergic nerves not containing VIP innemate D-cell.
