Figure 3.
Expression of transient receptor potential melastatin-type 7 (TRPM7) protein in human colon. Double labeling of TRPM7-like immunoreactivity (red) and c-kit–like immunoreactivity (green) within smooth muscle layers of the human colon. The mixed color yellow indicates the colocalization of both TRPM7-like and c-kit–like immunoreactivity (bar = 50 μm). DIC: differential interference contrast.
