Abolished bladder (A,B) and ileal (C, D) smooth muscle contractions in response to carbachol in the M₂−/−M₃−/− mice. Responses to carbachol are shown (mean ± SEM) as percentages of those to 50 mmKCl in the male (A, C) wild-type, M₂−/−, M₃−/−, and M₂−/−M₃−/− mice and the female (B, D) wild-type, M₂−/−, M₃−/−, and M₂−/−M₃−/− mice. Each symbol represents the data of four experiments. The data of the M₃−/− mice have been published previously (Matsui et al., 2000).
