Figure 5.
Human MCp in bone marrow and peripheral blood demonstrate surface expression of CCR1 and CCR5. Ficoll-separated cells from bone marrow (BM) and blood of five healthy donors were stained with fluorescently-conjugated antibodies and analyzed by flow cytometry. (A) MCp were identified as CD4− CD8− CD19− CD14− CD34hi CD117+ FcεRI+ cells. (B) Representative histograms for CCR1 and CCR5 surface expression on blood and BM MCp. (C) The differential expression of CCR1 and CCR5 by MCp from blood and BM were compared and illustrated as a difference in gMFI. Each donor is labeled by a specific color. The bars show the mean ± SEM. **p < 0.01.
