Migration and invasion induced by the CX3CR1/CX3CL1 interaction in hypoxic OvCa cells. OVCAR-3, SW 626, and TOV-112D cells were cultured in the presence of CoCl2 (150 μM) (to mimic hypoxia), and with or without CX3CL1 (chemoattractant) and KC7F2 (inhibitor) in the medium. Over 6 days, migration and invasion were assessed. (a) Morphology and (b) quantitative analysis of surface area, representing the invading cells projecting out of the spheroid into the medium when using CX3CL1. For cells under hypoxia, there was minimal growth, or they remained as aggregates when treated with or without the inhibitor, KC7F2
