Figure 3From: Doxorubicin loaded Polymeric Nanoparticulate Delivery System to overcome drug resistance in osteosarcoma Subcellular distribution of doxorubicin in drug sensitive and resistant osteosarcoma cell lines was analyzed under fluorescence microscope (A-C). A prominent increase in fluorescence was observedin the nucleus when multidrug resistant cells were treated withdoxorubicin loaded nanoparticles.Back to article page
