(A) Representative blots of ITGB, CTNNA1, CTNNB1, TLN1, FAK, VCL, PXN and GAPDH in intrascaffold-cultured osteosarcoma cells after 7 days. (B) Fold induction of ITGB, CTNNA1, CTNNB1, TLN1, FAK, VCL and PXN expression in intrascaffold-cultured osteosarcoma cells after 7 days. (C) Representative blots of ITGB, CTNNA1, CTNNB1, TLN1, FAK, VCL, PXN and GAPDH in intrascaffold-cultured osteoblasts after 7 days. (D) Fold induction of ITGB, CTNNA1, CTNNB1, TLN1, FAK, VCL and PXN expression in intrascaffold-cultured osteoblasts after 7 days. n=3; mean ± SD; *P<0.05, **P<0.01, ***P<0.001; NS, not significant. L, M and H correspond to low (0.05% GelMA), middle (0.2% GelMA) and high (0.5% GelMA) adhesion ligand density.
