  1. The results were measurement data and expressed as mean ± standard deviation. Data comparison among multiple groups was analyzed by one-way ANOVA, followed by Tukey’s post hoc test. The experiment was repeated 3 times independently
  2. *p < 0.05 vs. the control group at the same time
  3. #p < 0.05 vs. the CS/SF group at the same time
