*2.9. Statistical Analysis*

All experiments were repeated at least three times on three independent samples. Oneway analysis of variance (ANOVA) followed by Dunnett's multiple comparison test was used for repeated measurement values. Differences of *p* < 0.05 were considered significant. Statistical analysis was carried out using GraphPad Prism Software (version 6.0c, GraphPad Software, San Diego, CA, USA).
