Ontogeny of the hypothalamo-neurohypophysial system in rats--an immunohistochemical study.
In fetal rats neurophysin has been visualized immunohistochemically first at the 16th gestation day in perikaryons of the supraoptic nucleus, followed by the median eminence and the neurohypophysis at the 17th day, and the paraventricular neurons at the 19th day. The external zone of the median eminence contains abundantly immunoreactive fibres at the first days post partum. In the perikaryons of the suprachiasmatic nucleus immunoreactive material appears after the 3rd day of postnatal development.
