Movie 8.

Dynamic microtubule polymerizing in-between close actin branched meshwork with a high angle of interaction. Time-lapse imaging of dynamic microtubules (green) polymerizing in between two branched actin networks (magenta), without actin bundles (100nM of Arp2/3 complex), at an angle greater than 60°. Yellow arrow show the point of contact between microtubules - tip and the branched actin meshwork. White arrow show microtubule + tip piercing the branched actin meshwork. Scale bar, 10 µm.
