A: Representative flow cytometric analyses of time-dependent (0.5 - 2 hours) uptake of BCMA peptide-FITC by immature dendritic cells, as (1) free peptide, (2) encapsulated in PLGA, or (3) encapsulated in liposome. B: A summary of three independent flow cytometric analyses (N=3), showing time-dependent (1 - 18 hours) uptake of BCMA peptide-FITC by immature dendritic cells, as (1) free peptide, (2) encapsulated in PLGA, or (3) encapsulated in liposome. C: Representative confocal microscopic analyses of (1) immature dendritic cells alone (no peptide pulsed), (2) immature dendritic cells pulsed with BCMA peptide-FITC, or (3) immature dendritic cells pulsed with BCMA peptide-FITC encapsulated PLGA nanoparticles after pulsing for 18 hours.
