Figure 8

Unlabeled Dictyostelium cells (70%) were mixed with RFP-expressing cells (30%) in starvation buffer and incubated for 17 hours to induce chemotactic aggregation. When mixed with unlabeled wild-type cells, RFP-expressing β1/2- cells migrated in streams (A), similar to mixed populations of labeled and unlabeled wild-type cells (B). Mixed populations of labeled and unlabeled β1/2- cells did not aggregate in response to starvation conditions (C). Scale bar, 100μm.
