Fig. 4. MT dynamics at steady-state. Fluorescently labelled microtubules were imaged at the periphery of living melanophores after pigment aggregation. Imaging was begun 2 hrs after injection of Cy-3 labeled tubulin and 1 hr after stimulation of aggregation by adrenalin. Arrowheads directed to the right indicate growing ends of MTs and arrowheads directed to the left indicate shortening ends. Time in seconds shown in lower left corner. Bar, 5 µm.
