Fig. 4From: An advanced glioma cell invasion assay based on organotypic brain slice culturesImproved image quality by DiD labeling and confocal imaging. Representative pictures of epi-fluorescence (a, c) and confocal microscopy (b, d). Usage of DiD (c, d) improves picture quality compared to DiI labeling of SMA560 cells (a, b). Scale bars 100 μm, image quality was optimized by adjustment of brightness, contrast and gammaBack to article page
