(A) Fluorescence images representing the distribution of red-stained M0 or M1 macrophages co-cultured with rFLS at different time points (Scale bar: 200 μm); (B, C) SEM and optical micrographs representing the co-culture of FLS with either resting (M0) or inflammatory (M1) macrophages (yellow arrowheads: M0 or M1 macrophages; white arrowheads: rFLS cells). Scale bars: 20 μm (optical) and 50 μm (SEM).
