Figure 4. — MMP2 and MMP9 expression levels in FBs following incubation with Piwil2-iCSC-Exo (200 µg/ml). GAPDH was used as a loading control. At least three independent experiments were conducted. Results were considered statistically significant at P<0.05 (*P<0.05, **P<0.01 vs. control group; ^#P<0.05 vs. PBS group). One-way ANOVA and the LSD post hoc test were selected for analysis. FBs, fibroblasts; Piwil2-iCSC-Exo, exosomes derived from Piwil2-induced cancer stem cells; MMP, matrix metalloproteinase.
