Additional file 2: Figure S2. of Hybrid clone cells derived from human breast epithelial cells and human breast cancer cells exhibit properties of cancer stem/initiating cells

M13HS hybrid clones are mononuclear. The morphology of M13HS hybrid clone cells resembles more to the morphology of parental HS578T-Hyg human breast cancer cells than to M13SV1-EGFP-Neo breast epithelial cells. Please note that the EGFP fluorescence of M13SV1-EGFP-Neo cells and M3HS hybrid clone cells was not visualized here due to the much brighter fluorescence of SYTOX Green. Shown are representative images. Bar = 20 μm. (TIFF 12426 kb
