Fig. 5. Bacitracin inhibits U87-MG cell invasion in brain-slice. A : The cells radiate out in all direction and exhibit a high invasiveness. B : The cells cultured in the media contained 2.5 mM bacitracin, aggregate in the hole of the brain-slice. Although the cells show a high density, they always exhibit a low invasiveness, compare with control group. All the images are obtained by confocal laser scanning microscopy (100×magnification).
