Localization of somatostatin-like immunoreactivity in the Golgi apparatus of central and peripheral neurons.
With the indirect immunofluorescence technique of Coons and collaborators somatostatin-like immunoreactivity (SLI) was observed in certain neurons of the central and peripheral nervous system of the rat. In the cell bodies a strong SLI was observed with a distribution resembling that of the Golgi apparatus. In addition a weak SLI was diffusely distributed in the cytoplasm. After photography the sections processed for immunocytochemistry were stained with the thiamine pyrophosphatase technique of Novikoff and Goldfischer. The latter technique is assumed to be a specific marker for the Golgi complex. It was found that the strong SLI and the thiamine pyrophosphatase activity had an identical distribution. Thus, one pool of somatostatin appears to be localized to the Golgi apparatus.
