Fig. 3From: Doxorubicin resistance in breast cancer cells is mediated by extracellular matrix proteinsDiffusion of doxorubicin within 3D cell cultures for MDA-MB-231 and MCF-7 cell lines. The vehicle (negative control) and doxorubicin concentrations were evaluated. Images captured (central slice shown) at 6, 24 and 72 h time points. Image analysis was completed utilising the radial profile plugin in ImageJ. Scale bar = 50 μmBack to article page
