Somatostatin-like immunoreactivity in the amygdala of the pig.
The distribution and morphology of neurons containing somatostatin (SOM) was investigated in the amygdala (CA) of the pig. The SOM-immunoreactive (SOM-IR) cell bodies and fibres were present in all subdivisions of the porcine CA, however, their number and density varied depending on the nucleus studied. The highest density of SOM-positive somata was observed in the layer III of the cortical nuc...
متن کاملDevelopment of somatostatin-like immunoreactivity in embryonic sympathetic ganglia.
Neural crest cells are the embryonic progenitors of several adult cell types, including some neurons that contain the neuroactive peptide somatostatin. To begin to understand the control of peptide expression during neuronal ontogeny, we have investigated the development of somatostatin-like immunoreactivity (SLI) in embryonic quail paravertebral sympathetic ganglia in vivo. SLI was identified ...
متن کاملCharacterization of somatostatin-like immunoreactivity in vertebrate retinas.
Large differences in retinal concentration of somatostatin-like immunoreactivity (SLI) were observed even among closely related species. Hog and chicken retinas, like those of goldfish and frog described previously, contained roughly equal amounts of SLI coeluting with somatostatin tetradecapeptide (S14) and octacosapeptide (S28) on Sephadex G 50 chromatography. In contrast, virtually all of th...
متن کاملLocalization of substance P-like immunoreactivity within the monkey retina.
Substance P (SP)--like immunoreactivity has been localized to distinct retinal cell populations in the primate Macaca nemestrina by means of immunohistochemical techniques with a well-characterized monoclonal antiserum directed to SP. The specificity of the immunoreactive staining was established by absorption of the antiserum with 10 micro M synthetic SP. Specific SP-like immunoreactivity was ...
متن کاملProperties of endogenous somatostatin-like immunoreactivity and synthetic somatostatin in dog plasma.
Somatostatin-like immunoreactivity (SLI) in the peripheral venous plasma of dogs and in their pancreatic and gastric venous effluents was characterized and compared with synthetic somatostatin. Both endogenuous plasma SLI and somatostatin added to plasma were eluted from Sephadex gels at pH 8.8 in the 150,000--200,000-mol wt region but at pH 2.5 both appeared in the 1,500--2,000-mol wt region. ...
