AhR expression modulates cell migration in epithelial cells. Wild type (EV), sh-AhR, and CA-AhR NMuMG cells (A) or primary AhR+/+ and AhR−/− keratinocytes (B) were grown to confluence, and their ability to migrate was analyzed in wound healing assays after 48 h. The experiments were done in triplicate in three independent cultures of each genotype. Data are shown as the mean ± S.D. Bar, 200 μm. A.U., arbitrary units.
