(D) Distribution of distance to nucleus, normalized on cell size, quantified by image (as in c) segmentation (see Material and Method, Confocal microscopy and early/late quantification) of EEA-1+ endosomes in siCTL and siKIFC1 ECs. Results are from three independent experiments for a total of 4091 early endosomes in 19 siCTL cells (215 ± 20 endosomes per cell) and 2275 early endosomes in 20 siKIFC1 cells (114 ± 10 endosomes per cell) and analyzed by a two-tailed heteroscedastic Student's t-test, p≤ 0,001 ***.
