Cell motility in response to soluble wound factors. Primary keratinocytes were isolated from wild-type (WT) and CXCR3−/− mice and analyzed for response to a wound growth factor (EGF for the EGF receptor network) and the CXCR3 ligands (IP-9 and IP-10). In a two-dimensional in vitro “wound healing” assay, keratinocytes from both mice were equally responsive to EGF, but only the WT keratinocytes responded to IP-9 and IP-10 for induction of migration (mean ± SD; n=3; *p < 0.05). CXCR3, cysteine-X amino acid-cysteine receptor 3; EGF, epidermal growth factor.
