The cultured cells formed growth cones shaped like a thin lamellipodium for 1 to 3 days.
The peripheral actin ultrastructure of the growth cone has also been well characterized as being composed of two distinct structural domains: filopodia containing arrays of uniformly polarized (barbed end distal) actin filaments, and intervening lamellipodium domains with less polarized filament structure (cf figure 6a; Lewis and Bridgman, 1992).
The larger (10 [[micro]meter] diameter) pieces developed a broad, skirt-like lamellipodium or extended long filopodia into which the cytoplasm streamed.
