Fig. 4. Distances of fusion sites of vesicles from the nearest Golgi element in untreated or nocodazole-treated stationary and migrating fibroblasts. The distances from each site of fusion (mapped in Fig. 2) to the closest Golgi element (before the release of the Golgi block) were measured for stationary (A) and migrating (B) cells. The data from untreated and nocodazole-treated cells are coded in black and grey, respectively. To normalize for cell size, the distance values are displayed as the percentage of the maximal distance between the centre of the Golgi and the furthest edge of the cell. The counts are normalized to the total counts (notice the axis break).
