Figure 2. Imaging WT cells at large forces causes substantial ultrastructural changes.

(a) Height and (b) deflection images of the polar region of an L. lactis WT cell recorded with an applied force of 5 nN. The inset shows a high-resolution deflection image recorded in the square region. (c) Statistical analysis of the width of the periodic features observed in height images (n=45 measurements on two different cells, average width ± s.e.m.).
