Figure 2From: Doxorubicin loaded Polymeric Nanoparticulate Delivery System to overcome drug resistance in osteosarcoma Fluorescence of KHOS, KHOS R2 (A), U-2OS, and U-2OS R2 (B) after treatment with doxorubicin aloneor nanoparticle loaded with doxorubicin was analyzed by flow cytometry. The effect of nanoparticle was potent enough that thefluorescence of MDR osteosarcoma cells was comparable to that of drugsensitive variants.Back to article page
