Immunological detection of somatostatin in a primitive hypothalamic mouse cell line, precursor of a neurophysin cell lineage.

A primitive nerve cell line (F7 clone), obtained by SV 40 transformation of mouse fetal hypothalamic cells, has been previously shown to share some properties with a progenitor cell for neurophysin synthesizing neuron. This paper describes the immunological detection, at the light microscope level, of somatostatin in this cell line. A SV 40 transformed neurosecretory clone, synthesizing neurophysin and vasopressin, was used as control.
