Doxorubicin-resistant cells have a high adhesion effect to umbilical vein endothelial cells (ECs). The adhesion of DRM cells to Endothelial cells (ECs) was significantly increased with the advancement of resistance to higher concentrations of doxorubicin. The cells were washed, and the resistant cells adhered to ECs were counted. (A) The attached cells were photographed using a light microscope (B) Graphical representation of a number of cells attached. The values expressed as mean ± standard deviation (SD) (n = 5) (* p < 0.05, **p < 0.001 vs. control). DRM: Doxorubicin-resistant MDA-MB-231.
