EZH2-mediated inhibition of microRNA-22 promotes differentiation of hair follicle stem cells by elevating STK40 expression

Figure 7. EZH2-mediated miR-22 suppression promotes proliferation and differentiation of HFSCs. (A) The expression of miR-22, and mRNA expression of STK40, MEF2 and ALP in HFSCs of EZH2-/- mice or WT mice determined by RT-qPCR. (B) Protein expression of STK40, MEF2, ALP, differentiation-related proteins (β-catenin, TCF-4), and TA cell differentiation markers (CK15, CK19) in HFSCs of EZH2-/- mice or WT mice normalized to GAPDH determined by Western blot analysis. (C) Colony forming capacity of HFSCs from EZH2-/- mice or WT mice determined by colony formation assay. (D) The proliferation and viability from EZH2-/- mice or WT mice evaluated by MTS assay. (E) HFSCs from EZH2-/- mice or WT mice at different cell phases observed by flow cytometry. * p < 0.05 vs. WT mice; # p < 0.05 vs. NC-inhibitor (EZH2-/-) group; Measurement data were expressed as mean ± standard deviation. One-way ANOVA was utilized to compare data among multiple groups, followed by Tukey’s post hoc test. Repeated measures ANOVA was adopted to analyze data among multiple groups at different time points, followed by Bonferroni posttest. Cell experiments were conducted in triplicates.
