Fig. 2From: Role of nanoparticle size and sialic acids in the distinct time-evolution profiles of nanoparticle uptake in hematopoietic progenitor cells and monocytesTime-evolution of the loading of THP-1 cells demonstrated as median fluorescence intensity (FI) obtained by flow cytometry. THP-1 cells were exposed to 50 µg/ml of 40 (a), 100 (b) or 200 nm (c) PS NPs and monitored up to 6 h. Profiles of 3 THP-1 cultures with different passage number are shownBack to article page
