LPA stimulation increases FA size in a PP2-sensitive manner.
Top: Deconvolution microscopy of FAs. Representative FAs are shown in an expanded view in the insets. All FAs in each cell, not just those featured in the insets, were analyzed to determine the mean FA area. Scale bars: top, 20 µm; bottom, 5 µm. Bottom: Mean FA area is significantly greater in cells stimulated with LPA (n = 82 cells). ***p<0.001, unpaired, two-tailed Student’s t-test.
