title: [In vitro culture of the hypothalamic supraoptic nucleus. I. General morphological characteristics].
abstract: Kinetics and morphology of supraoptic nuclei (SON) organ culture of newborn rat hypothalamus have been described. Explants of SON were cultured for 7-90 days. Cell migration, growth of neuron sprouts, formation of nerve bundles and growth zone, and mitotic activity were followed. Neurosecretory cells (NSC) differing in size, shape and degree of activity, were identified in addition to other cell elements of SON. The neurosecret was shown to appear at the beginning of the second week of cultivation in large and middle size NSC. In small and old cultures of NSC no neurosecrete was discovered. It was established that NSC complete the terminal differentiation and maintain for a long time their viable and functional activity in vitro.
