Movie 5.

Dynamic microtubule breaching inside a branched actin network. Time-lapse imaging of a dynamic microtubule (green) polymerizing in between two branched actin networks (magenta) in presence of actin bundles (10nM of Arp2/3 complex). The yellow arrow shows the point of contact between the minus end of the microtubule and the branched network. The white arrow shows the plus end of the microtubule breaching inside of the branched actin network. Scale bar, 10 µm.
