Migration analysis of MSCs under different conditions. (A) Cell migration was examined via wound healing assays, in which cells were wounded by scratch injury (black lines), scale bar: 400 μm. (B) The cell migration rates were determined. (C) Migration analysis in an agarose spot assay, representative images of MSCs migration assay into a PBS-, IL-1β-containing agarose spot at the indicated times, black lines indicate agarose gel boundaries, scale bar: 100 μm. (D) The diatance migrated from the border of the anarose spot was measured for MSCs, MSCs-V and MSCs-3IL at the indicated times. Data are presented as mean ± SD. *P < 0.05, **P < 0.01, ***P < 0.001
