Fig. 4From: Analysis of Actin and Focal Adhesion Organisation in U2OS Cells on Polymer NanostructuresNumber of FAs, combined FA area per cell and fraction of FA area to cell area for cells imaged on three different surface types (flat and pillar arrays with pitches of 1000 nm and 2000 nm). Each grey point corresponds to an observation from one cell. Statistical significance between the distributions was determined using Mann–Whitneys non-parametric testBack to article page
