Fig. 3From: Nanoliposomal VEGF-R2 peptide vaccine acts as an effective therapeutic vaccine in a murine B16F10 model of melanomaIn vitro cellular uptake of DiR-labeled liposomes by PBMCs. PBMCs incubated with nanoparticles for 2 h either in 4 °C and 37 °C. The cellular uptake in PBMCs incubating with nanoliposomes at 4 °C was similar to that of untreated group, while PBMCs that were incubated at 37 °C showed a significant level of uptakeBack to article page
