Summary of the double blind analysis of actin fluorescence.

Treatment	Cell-Cell Boundaries			Filopodia Clusters			Mean Total Actin Fluorescence in Filopodia per Cell (±S.D.)
	Total Cell Boundaries	Mean Pixel Intensity (±S.D.)	P-valuea (vs shRb H)	Total Cells	Proportion of cells with filopodia	P-valueb (vs shRb H)

^aP-values were determined using the Kruskal-Wallis with Dunn’s multiple comparisons test.

^bP-values were determined using the Fisher’s exact test.
