Cell to cell adhesion
Cell to cell adhesion 
between live Dictyostelium cells was measured in a collaboration with Gerisch's group at the MPI Martinsried. Controlling the interaction force, and by means of this the size of the interacting membrane areas between the two cells, and by allowing minimized time for this cellular interaction, we were able to measure the adhesion forces between the cells down to the level of individual cell adhesion molecules. By genetic engineering the cell adhesion proteins and their regulation were altered and the resulting changes in adhesion forces were investigated. The future of this kind of experiments lies in the development of functional genomic assays based on transient or permanent transfection.

Cell adhesion is fundamental for locomotion, for food uptake of individual cells and for arranging multicellular organisms. Cell adhesion plays crucial roles in navigation of immune cells, regulating the bloodstream (thrombosis/clotting) and became subject in medical, pharmaceutical and therefore basic research.
