Neurochemical features of endomorphin-2-containing neurons in the submucosal plexus of the rat colon

Figure 1 Immunofluorescence histochemical double-staining of the whole-mount sections of the rat mid-colon. The distributions of endomorphin-2-immunoreactive (IR) neurons (A), neuron-specific enolase (NSE)-IR neurons (B) and EM-2/NSE co-localized neurons (C) in the submucosal layer. Arrows point to the representative neurons containing both EM-2- and NSE-IR products. Scale bar = 45 μm.
