TE promotes expression of VCL and cell spreading in IPFP-MSCs. (A) VCL immunofluorescence staining and morphology of the cytoskeleton in IPFP-MSCs at 2, 6, and 12 h after adherence. Blue arrows indicate intensive expression location of VCL. (B) Fluorescent quantitative analysis of VCL in IPFP-MSCs at 2, 6, and 12 h after adherence. (n = 5, *P < 0.05, **P < 0.01, ***P < 0.001). (C) and (D) Western blot of VCL and its statistical analysis (2, 6, and 12 h). (n = 3, *P < 0.05, **P < 0.01).
