Fig. 7From: Microtubule cytoskeleton-disrupting activity of MWCNTs: applications in cancer treatmentMWCNTs interference with the cell cycle. a Diagram comparing mitosis in untreated versus MWCNT-treated cells. Spindle formation is abnormal (apolar, tripolar, or multipolar) in the presence of MWCNTs leading to mitotic blockage and apoptosis. b Phases of a normal cell cycle (top) compared to that in cells treated with MWCNTs (bottom)Back to article page
