Fig. 2From: Mechanism of induction of binucleated cells by multiwalled carbon nanotubes as revealed by live-cell imaging analysisTime-lapse analysis of cell division involving MWCNT fibers (25.3 μg/mL). a Short MWCNT fibers (approximately 5 μm) did not inhibit cell division. b Long MWCNT fibers (approximately 20 μm) inhibited cytokinesis and induced the formation of binucleated cells (the white dotted line in the image at 5 h 40 min). Time (h:min) is shown at the top. Bar, 41 μmBack to article page
