The enteric nervous system is formed by neural crest cells that proliferate, migrate and colonize the gut. Neural crest cells differentiate into neurons with markers specific for their neurotransmitter phenotype. This protocol describes a technique for dissecting, fixing and immunostaining of the murine embryonic gastrointestinal tract to visualize enteric nervous system neurotransmitter expression.
Overview
This article presents a protocol for dissecting, fixing, and immunostaining the murine embryonic gastrointestinal tract. The focus is on visualizing neurotransmitter expression in the enteric nervous system, which is derived from neural crest cells.
