Fig. 9. The frequency of wave initiation in the cAR1 affinity receptor mutants. Histogram showing the distribution of wave initiation periods and wave velocities of the mutant IIIb21 at the aggregation stage of development. The waves are concentric and the mutants do not fire successive wave from the same centre. Consequently, the cells do not aggregate. (A) Concentric darkfield wave initiated in random locations. (B) Time-space plot showing the disappearance of the waves after 6 hours. (C,D) Comparison of wave velocity and period between IIIb21 and N272.
