Comparison of protein expression of Collagen I, CTGF, YAP, and SMAD3 after treatment with EXO and EXOPDGFBB. a Immunofluorescence assays of CTGF (Green). DAPI was used to stain nuclei (Blue). b Immunofluorescence assays of YAP (Red) and phospho-SMAD3 (Green). DAPI was used to stain nuclei (Blue). c Western blots of molecules expression of Collagen I, CTGF, phospho-YAP, YAP, phospho-SMAD3, and SMAD3 among the control group, EXO group, and EXOPDGFBB group. Full-length blots are presented in Additional file 2: Fig. S2c. Data were mean ± SD, *P < 0.05, **P < 0.01, ***P < 0.001 for One Way ANOVA
