Figure 5. Cellular uptake of liposomes quantified by fluorescence intensity.

Figure 5

The difference in total uptake between liposomes with and without c(RGDyC) modification was statistically significant (p < 0.05) in HUVEC and U87 cells. Cells pre-treated with c(RGDyC) peptides were subsequently incubated with c(RGDyC)-LP. Cell aggregation in c(RGDyC)-LP treated HUVEC and U87 cells may have contributed to the relatively large error bars. Results are expressed as mean ± SD (*: p <0.05, **: p<0.01, and NS: p>0.05, n=3).
