Migration of α_Mβ₂ WT 293 transfected cells was assessed as in the legend to Fig. 1 A to different concentrations of Fg placed either in the upper or lower transwells. Data are means of cells per HPF for duplicate wells from three or more experiments expressed as percentage of WT (migration to 50 μg/ml Fg, lower well).
