Directed-migration of fibroblasts using the opto-CXCR4 system. Cells migrate following a gradient of light, the centre of the light source is depicted (+). Untransfected cells (not mCherry positive) do not migrate and light has no effect on them.

Directed migration of fibroblasts (red), to the direction of light (circle with cross). While fibroblasts migrate they interact with other cells (green) via an engineered receptor system that can be controlled by a small compound.

This assay has been used to determine the functionality of patient-derived mutant gonadotropin receptors (Rivero-Müller A, et al. 2015 Jun;172(6):K27-36. doi: 10.1530/EJE-14-1095) and the luteinising hormone beta subunit (LHB) (Potorac I, et al. 2016 Dec;231(3):197-207), as well as the interactions between ligand-loaded nanoparticles to the trageting receptor (from our work Paramonov V, et al. Nanotheranostics 2018; 2(4):320-346. doi:10.7150/ntno.23826):
