Fig. 2 - Inhibitors of motor activity interfere with MT rearrangement in melanophore fragments. Pigment distribution (left columns) and arrangement of MTs (middle columns) in melanophore fragments injected with buffer (upper row) sodium orthovanadate (middle row) or kinesin antibody (lower row) and stimulated to aggregate (left panel) or disperse (right panel) pigment granules; numbers in right columns of each panel indicate number of fragments with radial arrangement of MTs per total number of fragments tested. Bars, 20 mm.
