Comparison of two cells with stained actin filaments: With WAVE complex and after genetic removal of the WAVE complex. The WAVE complex is important for the formation of lamellipodia. In the cell without WAVE complex, these lamellipodia, i.e. the actin filament-rich networks at the cell edge, are missing. Picture credits: Klemens Rottner and Frieda Kage/TU Braunschweig
