Fig. 7. Co-localization of ß-catenin with cadherin and plakoglobin with desmoplakin at the intercalated disc in control and CKO mouse hearts. Frozen sections were double stained for cadherin (A, control; D, CKO) and ß-catenin (B, control; E, CKO) or desmoplakin (G, control; J, CKO) and plakoglobin (H, control; K, CKO). Merged images of ß-catenin and cadherin double staining are shown in C (control) and F (CKO) and those of plakoglobin and desmoplakin in I (control) and L (CKO). All images represent stacked confocal slices taken every 0.5 µm through the tissue section at a magnification of 63x and a zoom factor of 1.00. Bar, 30 µm.
