CD49d levels on blood, bone marrow, and MIP-2–mobilized neutrophils. Cell surface expression of CD49d on neutrophils from a nonperfused bone marrow, and those mobilized from the perfused femoral bone marrow following a 10-minute infusion of either vehicle or MIP-2 (1 nM). (A-B) Expression of CD49d and the isotype-matched control mAb (ic) is shown. Histograms are representative of n = 3 to 5 separate perfusions with staining performed in triplicate. (C) Combined results are expressed as the mean of the specific geomeans ± SEM (n = 3-5 separate rats or perfusions). ^*P < .05.
