From: Artificial modulation of cell width significantly affects the division time of Escherichia coli

Cell division is promoted in ‘necked’ channels. (a) Schematic of microchannels with periodic necks. The enlarged section is the top view of the necks. (b) Time-lapse images of two representative cells with fluorescently labeled nucleoid (HU-mCherry), which are in straight channel (upper panel, \(\varphi\) = 0, time interval is 4 min) and ‘necked’ channel (lower panel, \(\varphi\) = 0.84, time interval is 2 min). (c) The correlation between division time t and the constriction ratio \(\varphi\) for cells in ‘necked’ channel. For all quantitative data, each value is mean ± SD. Sample size for each group is shown in Supplementary Table S4.
