CXCR3 expression is decreased while CXCR6 expression is unchanged on SSc ECs compared to HMVECs. HMVECs (A) and SSc ECs (B) were cultured on gelatin-coated chambers and immunofluorescence stained. Staining with specific antibodies against CXCR3, CXCR6, or irrelevant IgG control is shown. Nuclei were counter stained with DAPI. Staining was detected using a fluorescence microscope and images were taken at 400×.
