Neutrophils hitchhiking by BSA-NPs. A Fluorescent images of neutrophils incubated with BSA-NPs (green) for indicated times. DAPI (blue) was used as a counter staining. Scale is 50 μm. B Quantification of FITC-BSA-NPs uptake by neutrophils in A. C Schematic drawing of the in vitro co-culture system. D Fluorescent images of BSA-NPs location after the co-culture of neutrophils and stromal cells for indicated times. Scale is 20 μm. Data are shown as mean ± SEM and were analyzed by one-way ANOVA with Turkey’s post hoc test. ***P < 0.001
