Figure 2.
4T1 cell viability after 24 h incubation with free GA (solution), blank NLC, GA-NLC, c(RGDfK)-GA-NLC, and E-[c(RGDfK)2]-GA-NLC to 4T1 cells. At lower concentration of GA, c(RGD) peptides modified GA-NLC showed significantly lower cell viability (%). Free GA was able to inhibit the growth of 4T1 cell only at higher concentration (*p-value <0.05 represent vs GA-NLC).
