The Journal of Cell Biology, Volume 158, Number 1, July 8, 2002 31-37Dual-wavelength fluorescent speckle microscopy reveals coupling of microtubule and actin movements in migrating cells Wendy C. Salmon, Michael C. Adams and Clare M. Waterman-Storer

Shows dual-wavelength FSM of microtubules (green) and f-actin (red).

Shows that the retrograde flow of microtubules oriented perpendicular to the leading edge in the lamellipodium is coupled to the movement of immediately adjacent lamellum f-actin speckles.
