NC-37 cells express functional CXCR5 and CCR7. A: Flow cytometry analysis of chemokine receptor expression by NC-37 cells. Open histograms show receptor-specific staining; filled histograms show isotype controls. Relevant controls are color-matched. B: Assessment of bare filter NC-37 cell migration to a range of concentrations of CCL19, CXCL12, or CXCL13. The mean ± SEM of six wells per concentration is shown. Representative of 3 independent experiments.
