Fig. 2. Expression of channelrhodopsin-2 (ChR2) in mouse colon. (A) TdTomato-positive cells were detected in the colonic muscularis in Kit-ChR2(+) mouse colon (scale bars = 400 μm). (B) No tdTomato-positive cell was observed in Kit-ChR2(–) mouse colon (scale bars = 200 μm). (C-E) ChR2 was expressed in Kit-positive cells. Red represents tdTomato and green represents Kit (scale bars = 50 μm).
