Fig. 3From: The anti-tumor and renoprotection study of E-[c(RGDfK)2]/folic acid co-modified nanostructured lipid carrier loaded with doxorubicin hydrochloride/salvianolic acid AThe cell viability of HEK293 cells treated with DOX solution and DOX/Sal A solution. The concentration range of DOX was 0.4–4.0 μg/mL, and the concentration of Sal A at each point was about 10 times to that of DOXBack to article page
