Fig. 7.

(A) Protein and mRNA levels in human SMSCs after being treated with soft or stiff matrix [(A1) the mechanical properties of silicon rubber and polystyrene culture plate, n = 3; (A2) Western blot analysis, the red arrow indicates dephosphorylated NFATc1, the blue arrows indicate phosphorylated NFATc1; (A3) the semiquantitative analysis of Western blot, n = 3, unpaired t test; (A4) the alcian blue staining; (A5) the semiquantitative analysis of alcian blue staining, n = 3, unpaired t test; (A6) the mRNA levels, n = 8, unpaired t test]. (B) Immunofluorescent assessment of FAK in regenerated tissue of PCL scaffold + synovium transplant group and native porcine menisci [(B1) the immunofluorescence of FAK; (B2) the semiquantitative analysis of FAK, n = 6, one-way ANOVA]. (C) Immunofluorescent assessment of pFAK in regenerated tissue of PCL scaffold + synovium transplant group and native porcine menisci [(C1) the immunofluorescence of pFAK; (C2) the semiquantitative analysis of pFAK, n = 6, one-way ANOVA]. *P < 0.05, **P < 0.01, ***P < 0.0005, ****P < 0.0001; ns, not significant.
