WIP deficiency does not affect fibroblast morphology or protein content.

<p><b>a</b> Representative western blot of WIP, N-WASP and Nck expression in soluble lysates of lung-derived fibroblasts from WIP^+/+ and WIP^−/− mice. Numbers indicate relative expression levels of each protein to GAPDH content and control fibroblasts determined by densitometry. GAPDH labeling confirmed equivalent protein loading control. <b>b</b> FACS analysis of forward and side scatter in control (WIP^+/+) and WIP^−/− fibroblasts. <b>c</b> Phase-contrast images from plated control (WIP^+/+) and WIP^−/− murine fibroblasts do not show evident morphological differences between both populations. Scale bar 50 µm.
