(F) Colocalization of ERGIC-53 and BET1 in control and P2-derived fibroblasts. Representative immunofluorescence images of ERGIC-53 (green) and BET1 (red) in fibroblasts from P2 and a control cell line. Scale bar: 20 µm. PCC (right panel) for BET1 versus ERGIC-53 (C1: n=72, C2: n=46, C3: n=56 and P2: n=37). (*** = p≤ 0.001, one-way ANOVA was followed by Tukey's post-hoc test). Data represented are mean ± SEM of two independent experiments.
