Comments "The network of short, branched filaments at the leading edge is generally narrow, less than 1µm deep under the plasma membrane (Svitkina and Borisy, 1999). Further from the membrane, all of the filaments are long and unbranched (Small et al., 1978). Given the rate of movement (0.2µm per second) and the width of the zone of branched filaments, these branched filaments must be remodeled into long, unbranched filaments in about 5 s. The first step in this remodeling process must be dissociation of branches from the sides of their mother filaments."
