(b-d) MCF10.DCIS.com cells (104 cells) transfected with scrambled siRNA (siNC) or siRNA against RAB2A (siRAB2A) were plated onto 6-well dish. Representative phase contrast light microscopy images (b) and the distribution of cell numbers per cluster of the indicated cell number (c) are shown. Data are means ± SD of 10 fields (n > 60 cells/field) of independent 4 independent experiments. Bars, 100 μm. Efficacy of RAB2A gene silencing was verified by qPCR (d). Bar, 200 µm.
