Monocyte-to-macrophage development and IL-4-induced FBGC formation in vitro. Monocytes were cultured on RGD-adsorbed culture surfaces for 1.5 hr (Day 0), or otherwise unstimulated macrophage development was allowed to proceed until Day 3 or Day 10. To induce macrophage fusion and FBGC formation, IL-4 was added on days 3 and 7, and the cultures also terminated on day 10. (May-Grünwald/Giemsa, scale bar = 50 μm)
