Spatial and temporal dynamics of innervation during the development of fetal human pancreas.

2008

The delineation of pancreatic nerve innervations during fetal life may contribute to our understanding of pancreatic pain modalities after birth. The aim of this study was to characterize the spatial and temporal distribution of nerve structures in the human pancreas throughout gestation. Computer-based image morphometry with piecewise polynomial interpolation analysis was performed to quantify nervous structures in the head, body and tail of the pancreas. Nerve structures were detected by automatic immunostaining techniques using a polyclonal antibody against two S-100 proteins that reacts strongly with human S100A and B that are detected in Schwann cells. Immunoreactivity was found in the…
