CXCR6 expression in human gingival fibroblasts (HGF). (a) Total RNA was prepared from non-stimulated HGF. The expression of CXCR6 mRNA in non-stimulated HGF was analysed by reverse transcription–polymerase chain reaction, as described in the Methods. (b) Flow cytometric analysis of CXCR6 expression in non-stimulated HGF. The filled line represents CXCR6-specific fluorescence and the open line represents the background level of fluorescence caused by isotype matched antibody.
