K. Human monocytes purified from venous blood draws from healthy adult male volunteers were treated with human cytokines towards a monocytic lineage (hMDM), dendritic lineage (hMDC), or microglia-like lineage (hMicroglia). Cells were incubated with TRITC-dextran for 30 min prior to washing, fixing, and staining with DAPI. Representative photomicrographs from 30 images analyzed for each condition from n=3 biologically independent experiments are shown. Scale bars show 200 μm. L-N. Relative fluorescent signals were calculated as a percent of control-ASO treated cells. 30 images across 3 independent experiments were quantified for each condition, with each dot in the plot representing one image quantified. The group means were calculated and shown. Error bars represent ± SEM. Significance was assessed by one-way ANOVA with Tukey's post hoc test, with **** representing P <0.0001.
