BV2 cell culture exposed to CD11b immunofluorescent staining over time. A-G Immunofluorescent staining of no-treatment control cells at 2, 4, 6 8, 10, 16 and 24 h, respectively. H-N Staining of cells exposed to the IL-4 treatment at 2, 4, 6, 8 10, 16 and 24 h, respectively. Images were taken with approximately the same cell confluency at a magnification of 60× and show a higher density of processes in the no treatment control compared to the IL-4-treated cells until 16 h. Arrow indicates extended processes seen on the untreated BV2 cells at 6 h.
