Abstract
Using in situ hybridization with35S-labeled prepro-VIP cDNA probes, vasoactive intestinal polypeptide (VIP) mRNA was detected in tumor tissues from two cases of ganglioneuroblastoma associated with watery diarrhea syndrome. The distribution of VIP mRNA was confined to the cytoplasm of the cells showing ganglionic differentiation, whereas the undifferentiated neuroblastic cells failed to be labeled by the probe. These findings were consistent with the localization of VIP-like immunoreactivity in the same tumor tissues. Direct evidence is presented at the single cell level for the production of VIP by ganglionic cells in ganglioneuroblastoma.Keywords
