Figure 5 Effect of the induced atrial fibrillation on the connexin43 (Cx43) distribution in the membrane of rat atrial cardiomyocytes. Ratio of the membrane length positively stained (PLM) for Cx43 as referred to the total membrane length (LM) of the polar membrane and of the lateral membrane. The results are represented as mean ± SEM of 600 cells per experimental group. Significant difference between the staining of the polar membrane and the lateral membrane is indicated by an asterisk; significant difference against the directly frozen control group is indicated by the pound symbol (#) (level of significance p < 0.05).
