Oxygen availability (normoxia vs. hypoxia) modulates DFs: proliferation (A), metabolic activity (B) and migration (C). Foxn1.−/− DFs cultured under hypoxic or normoxic conditions with KCM (keratinocyte conditioned media) from Ad-Foxn1- or Ad-GFP-transduced keratinocytes were analysed with a BrdU incorporation assay followed by flow cytometry analysis (A; n = 4), MTT metabolic activity assay (B; n = 4) or scratch migratory assay (C; n = 4). Values are the lsmean ± SE; asterisks indicate significant differences between normoxic or hypoxic condition transduction (**p < 0.01)
