High CXCR7 expression of peripheral blood and bone marrow lymphocytes.

<p>(A) CXCR7 is expressed in peripheral blood leukocytes, however an increase in CXCR7 cell surface expression was observed in lymphocytes compared to monocytes and neutrophils. This difference was more apparent and significant when the cells were permeabilized (lymphocytes vs. monocytes, <i>P = 0.0265</i> and lymphocytes vs. neutrophils, <i>P = 0.0286</i>) showing that the localization of this receptor is mainly intracellular in B-lymphocytes, CD4⁺ T-lymphocytes and CD8⁺ T-lymphocytes; <i>Mann-Whitney</i> test.
