Fig. 9. myoA/myoF cells do not show any chemotaxis in natural waves of cAMP generated by control cells in mixtures. myoA/myoF cells were mixed with control (JH10) cells at a ratio of 1:9, respectively. After 8 hours, cells were motion analyzed. (A) Instantaneous velocity plots of a representative control and neighboring mutant cell. (B) Centroid tracks of a control cell and a neighboring myoA/myoF cell. The phases of the wave are noted along the tracks. The small arrow denotes direction of control cell.
