From: A novel Dictyostelium RasGEF required for chemotaxis and development
Appearance of EDTA-stable contacts in ( open symbols ) untreated and ( closed symbols ) cAMP treated cells. Cells of (squares) AX2 or (triangles) HSB61 were developed in suspension. At the developmental time indicated in the abscissa cells were taken, incubated with 10 mM EDTA and cell adhesion measured in the agglutinometer of Beug and Gerisch, as described in Methods. A representative experiment is shown.
