a Representative Western blot images and semiquantitative analysis of FAK and AKT signaling pathway protein expression b in MSCs cultured on the two kinds of scaffolds and c in MSCs cultured on the mesh-like scaffold with FAK inhibitor. The activation of FAK and the downstream AKT pathways was observed in MSCs cultured on the mesh-like scaffold. d, e Inhibitory effects of FAK and AKT on paracrine factor expression in MSCs cultured on the mesh-like scaffold detected via RT-PCR analysis and ELISA test. *p < 0.05, **p < 0.01, ***p < 0.001
