Fig. 10. Filopodial regulation. (A-D) Upper panels: F-actin in D16-C3
cells treated for 7 days with indicated dsRNAs; lower panels: histograms
showing total F-actin (fluorescent phalloidin) in arbitrary units versus total
cell number. Red line, mean actin levels in control cells. (E-L) Actin
(green); Ena (red). (E,F) Control and abl dsRNA. (G-L)
M/Zabl4 and wild type stained in parallel: frames in G and
H show areas enlarged in I-L. Scale bars: 5 µm.
