Fig. 8. Cell sorting between cadA^– cells and wild-type cells. Cells were developed in liquid for 4 hours and then either cadA^– or wild-type cells were labeled with DiI. Equal number of wild-type and cadA^– cells were mixed and shaken for 6 hours. (A) A pair of phase and epifluorescence images showing a random mixture of labeled and unlabeled cadA^– cells. (B) A pair of phase and epifluorescence images showing cell sorting between labeled cadA^– cells and unlabeled KAX3 cells. Scale bars: 20 µm. (C) The percentage of aggregates showing cell sorting was scored for the different cell mixtures. The DiI-labeled cell strain is indicated by an asterisk.
