Transwell migration assay was conducted on hBM-MSCs treated with 2-10mMPi mediums or GM. a The cell numbers for migration in 2-10mMPi mediums and GM over time (6 h, 12 h, 18 h). ‘*’ showed statistical significance with p value < 0.05 when compared to GM group. b The observation on the migration of hBM-MSCs at 6 h under fluorescence inverted microscope (× 400) c The observation on the migration of hBM-MSCs at 12 h under fluorescence inverted microscope (× 400) d The observation on the migration of hBM-MSCs at 18 h under fluorescence inverted microscope (× 400)
