Abstract
The immunoreactivity of anti-neuron-specific enolase (NSE) and anti-Leu-7 on formalin-fixed sections of human fetal salivary gland epithelium was determined by the avidin-biotin-peroxidase complex (ABC) method. In addition, expression of some neuropeptides such as vasoactive intestinal polypeptide (VIP), somatostatin (SRIF), and substance P in the human salivary gland epithelium during the gestational period was observed, whereas the other polypeptides examined, including glucagon, cholecystokinin (CCK), Leu-enkephalin, and calcitonin were absent. NSE and Leu-7 immunoreactivity in the fetal salivary gland epithelium was observed solitarily or in groups commonly restricted to the developing duct epithelium. Positive immunoreactivity was observed in 46 cases with NSE (73%) and 44 cases with Leu-7 (70%) in 63 fetal salivary glands examined. In contrast, the incidence of positive cases stained with neuropeptides was lower than those of NSE and Leu-7 immunoreactivity in the human fetal salivary gland epithelium. These findings indicate that certain neuropolypeptides, as well as VIP, SRIF, and substance P present in the human fetal salivary gland epithelium may play a significant role in the development of the gland.
