Association of PS-containing liposomes with H5V cells. a) Representative T₁ and T₂ maps of H5V cell pellets incubated with the different types of liposomes in RPMI medium. b) Average R₁ and R₂ of H5V cell pellets measured at 9.4 T (n = 3/group). * p <0.05 vs. all, ANOVA with Bonferroni correction and † p <0.05 vs. RAW cell pellets, Student’s t-test. c) CLSM images of H5V cells. Top row: in red, the fluorescence signal of the NIR-lipids present in liposomes. The laser intensity (20% of maximal intensity) was ten times higher as compared to Figure 2d. Bottom row: NIR signal (in red) merged with signal of labeled H5V cell membranes (in green) and cell nuclei (in blue). Scale bar = 20 μm.
