Fig. 5. Dynamics of EFA6A ruffles and microvilli-like protrusions. (A) BHK cell expressing EGFP-EFA6A at the start of a time-lapse series. The box indicates the region of focus displayed as frames in B. Epifluorescence frames were obtained every 30 seconds. The arrows point to a ruffle that persisted during the entire series. Double-head arrows and arrowheads point to ruffles that formed or collapsed during the series, respectively.
