Fig. 3From: Comparison of circulating fibrocytes from non-asthmatic patients with seasonal allergic rhinitis between in and out of pollen season samplesRepresentative flow cytometry analyses of circulating fibrocytes showing the gating strategy, out vs in A tree pollen season and B grass or ragweed pollen season. Progenitor cells were selected based on the expression of CD34 (CD34 plots). Fibrocytes were selected afterward with gating of the CD45+ collagen I+ population (CD45 plots). Finally, the expression of the chemokine receptor CXCR4+ was measured (CXCR4 plots)Back to article page
