Abstract:
WGA-HRP retrograde tracing technique combined with immunohistochemical method was used to study the source of somatostatin postitive fibers in the posterior pituitary. Retrogradely labeled somatostatin immunoreactive cells distributed mainly in the periventricular area from the level of the anterior to posterior magnocellular paraventricular nucleus; single double labeled cells were also found in the periventricular areas at the level of the anterior commissure and posterior fornical nucleus. A few double labeled cells were seen in medial parvocellular paraventricular nucleus and the medial part of posterior magnocelluar paraventricular nucleus. The double labeled cells in the periventricular area lie mainly beneath the ependymal layer. Some were seen to intercalated in-between the ependymal cells, bringing themselves very close to the cerebrospinal fluid, but no direct fluid contacing elements were verified.
