Abstract

We describe the creation of cell adhesion mediated by cell surface engineering. The Flt3-ligand was fused to a membrane anchor made of the diphtheria toxin translocation domain. The fusion protein was attached to the surface of a cell by an acid pulse. Contact with another cell expressing the receptor Flt3 lead to its activation. This activity involved direct cell-cell contact. A mean force of 20 nN was needed to separate functionalized cells after 5 min of contact. Overall, we showed that it is possible to promote specific cell-cell adhesion by attaching protein ligands at the surface of cells.
