Fig. 1.

Histology of human gastric wall. As shown in panel A, we used fundus greater curvature, corpus greater curvature and corpus lesser curvature of human stomach. In HE staining of fundus greater curvature (Ba), we identified oblique, circular and longitudinal muscles. And then in c-Kit immunostaining (Bb), we observed c-Kit positive immnuhistochemical reactivity of ICC, which appeared as dark brown spots. Sub M, submucosa; O, oblique muscle; C, circular muscle; My, myenteric region; L, longitudinal muscle.
