FPR1 and cancer: Post-analysis of time-lapse video recordings in this OOC system allowed the extrapolation of high numbers of single cell tracks associated to high interaction times between immune cells (including DCs) and cancer cells, showing that immune cells with intact FPR1 perform biased random walks toward anthracycline-treated cancer cells, while those with mutated FPR1 show uncorrelated random walks (Biselli et al., 2017).
