Fig. 1From: Macrophages release IL11-containing filopodial tip vesicles and contribute to renal interstitial inflammationRepresentative images of FTV. A TEM images of FTV characterized by nanotubular filopodia (triangle). Scale bars: 200 nm. B SEM reveals that FTV(arrow) typically grow either on or at the tips of the nanotubular filopodia (triangle). Scale bars: 500 nm. C1 SEM images of macrophage cells (RAW264.7) on the coverslip surface. C2 Some residual FTV on the coverslip surface after extensive washing. Scale bar: 500 nm. D In situ TEM images of small internal vesicles were observed within the nanotubular filopodia as well as in the tip vesicle of FTV. Scale bar: 500 nmBack to article page
