Figure 7. Characterization of cardiac autonomic innervation in TOH/ChR2 mice.
A, confocal IF analysis on right atrium sections co‐stained with antibodies to HCN4 and td‐Tomato. B, confocal IF analysis on left ventricular sections co‐stained with antibodies to td‐Tomato and α‐actinin. C and D, confocal IF analysis on right atrium (C) and left ventricle (D) heart sections, co‐stained with antibodies to td‐Tomato and TOH. E and F, confocal IF analysis on heart sections from the right atrium (E) and left ventricle (F) of control and TOH/ChR2 mice, stained with an antibody to TOH. Nuclei were counterstained with 4′,6‐diamidino‐2‐phenylindole.
