Confocal laser scanning microscopy of intracellular SOX9 and SLUG localization. a M13SV1-EGFP-Neo human breast epithelial cells, b HS578T-Hyg human breast cancer cells, c M13HS-1 hybrid cells, d M13HS-2 hybrid cells, e M13HS-4 hybrid cells, f M13HS-7 hybrid cells, g M13HS-8 hybrid cells. White arrows indicate cells with a nuclear co-localization of SOX9 and SLUG. Cells with SOX9 in the nucleus and SLUG in the cytoplasm are marked with a green arrowhead, whereas red arrowheads indicate cells with a nuclear localization of SLUG. Shown are data representative of three experiments. Bar = 50 μm
