Fluorescence study of DNA uptake by cancer cells and their corresponding normal cells. A Rhodamine labeled AFP cDNA fragment (1.8 kb) was tested in Huh7 (a) and MDA-MB231 (b); also in their corresponding normal cells of THEL3 and HMEC. Huh7 and MDA-MB231 cells displayed a significant higher Rhodamine fluorescence density in the cytoplasmic phagosomes; but the normal cells did not. Intriguingly, some of the phagosomes can be counterstained by DAPI
