Supplementary 3: Filopodia numbers decrease along HaCaT cell membranes at later timepoints of infection.

Confocal microscopy images of cells incubated with virus for 4 hrs (A-D), 6hrs (E-H), and 8hrs (I-L). (A, E, I) DAPI stained the nucleus (grey) (B, F, J) phalloidin to visualize F-actin (green), and H16.V5 to stain L1 capsid protein (C, G, K). Merged images of every channel (D, H, L). Confocal images were obtained under oil using a 63X oil lens with a zoom factor of 1. Images are shown in X, Y, Z planes of a Z stacks.
