Chemotaxis of healthy cells to the fMLP chemoattractant. (A) The connecting line between the initial position and the end position of the cell in a migration medium. (B) The connecting line between the initial position and the end position of the cells in the 10 nM of fMLP gradient. (C) The connecting line between the initial position and the end position of the cells in the 100 nM of fMLP gradient. (D) The connecting line between the initial position and the end position of the cells in the 1000 nM of fMLP gradient. (E–H) Comparison of quantitative cells migration parameters including drifting index (AI), cell velocity (V), the migration displacement in the gradient direction (S), and the total migration distance (L).
