Localization of vasopressin mRNA-containing neurones in the hypothalamus of the monkey.

Neuronal perikarya containing vasopressin mRNA were detected in cryostat sections of cynomolgus monkey brains by using an in situ hybridization technique. The neurones were observed in hypothalamic regions (supraoptic nucleus, paraventricular nucleus, suprachiasmatic nucleus and accessory supraoptic nucleus). These findings are in agreement with previous reports using immunohistochemical methods.
