C, D TNT formation (marked by black triangles and white arrowheads) was imaged in control and shM2 H1299 (C) and shM2 A549 (D) cells by confocal microscopy. Scale bar: 60 μm. Boxed areas are enlarged and shown at the bottom of the corresponding images. E, F Quantification of the percentage of cells forming TNTs in control and shM2 H1299 (E) and shM2 A549 (F) cells. 13 images per group (E) and 10 per group (F) were captured for quantification. Three independent experiments were conducted. G Data information: data were analyzed by one-way ANOVA with Bonferroni post-test and shown as mean ±SEM; *** P < 0.001. Three independent experiments were performed
