Fig. 7. Polarized distribution of markers for clathrin-mediated endocytosis in the basal membrane of migrating cells. (A) The quantification of the relative dsRed-clathrin fluorescence intensity per unit area within three regions along the migrating axis of the cell. The average of seven cells ± s.e.m. is plotted. (B) The quantification of the relative dynamin2-EGFP fluorescence intensity per unit area within three regions along the migrating axis of the cell. The average of six cells ± s.e.m. is plotted. (C) The quantification of the relative Alexafluor488-transferrin fluorescence intensity per unit area within three regions along the migrating axis of the cell. The average of four cells ± s.e.m. is plotted.
