Establishment of the LV5-cortactin-SGC, LV5-SGC, LV3- shRNA-SGC, and LV3-SGC stable cell lines. A, E: LV5-cortactin-SGC; B, F: LV5-SGC; C, G: LV3-shRNA-SGC; D, H: LV3-SGC. The stable transfectants expressed green fluorescent protein. The left half of the figure was obtained under light field, and the right half was obtained under fluorescence. There is no morphological difference found between the stable cell lines.
