Distribution and chemical coding of neurons in intramural ganglia of the porcine urinary bladder trigone.

Distribution and chemical coding of neurons in intramural ganglia of the porcine urinary bladder... This study presents the distribution and chemical coding of neurons in the porcine intramural ganglia of the urinary bladder trigone (IG-UBT) demonstrated using combined retrograde tracing and double-labelling immunohistochemistry. Retrograde fluorescent tracer Fast Blue (FB) was injected into the wall of both the left and right side of the bladder trigone during laparotomy performed under pentobarbital anaesthesia. Ten-microm-thick cryostat sections were processed for double-labelling immunofluorescence with antibodies against tyrosine hydroxylase (TH), dopamine beta-hydroxylase (DBH), neuropeptide Y (NPY), somatostatin (SOM), galanin (GAL), vasoactive intestinal polypeptide (VIP), nitric oxide synthase (NOS), calcitonin gene-related peptide (CGRP), substance P (SP), Leu5-enkephalin (LENK) and choline acetyltransferase (ChAT). IG-UBT neurons formed characteristic clusters (from a few to tens neuronal cells) found under visceral peritoneum or in the outer muscular layer. Immunohistochemistry revealed four main populations of IG-UBT neurons: SOM- (ca. 35%), SP- (ca. 32%), ChAT- and NPY- immunoreactive (-IR) (ca. 23%) as well as non-adrenergic non-cholinergic nerve cells (ca. 6%). This study has demonstrated a relatively large population of differently coded IG-UBT neurons, which constitute an important element of the complex neuro-endocrine system involved in the regulation of the porcine urogenital organ function. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Folia histochemica et cytobiologica Pubmed
