FIGURE 5.

Abcam anti-CGRP: Partial projection confocal images revealed CGRP-IR axon innervation in the myenteric plexus at different regions of the stomach. (a, c, e) Ventral. (b, d, f) Dorsal. CGRP-IR axons traveled in the interganglionic connectives (arrows) and formed dense varicose terminals near and around many individual myenteric neurons (arrowheads; see FG-labeled neurons in Figure 6). As a note: the autofluorescent background of the muscles was relatively higher than that of Cell Signaling. Scale bar = 20 μm. A higher resolution version of this figure is available in the Supporting Information.
