Expression of diaFH3FH1FH2.Scer\UAS.P\T.T:Avic\GFP-EGFP under the control of Scer\GAL4en-e16E does not induce significant numbers of ectopic filopodia at the leading edge and there is little effect on protrusions of epidermal cells ventral to the leading edge. Lamellipodial area and filopodial number is similar to wild type in leading edge cells. Filopodial lifetime is significantly increased compared to wild type.
