CD44v6 and αvβ3 are highly expressed in granulocyte and monocyte but not lymphocyte subpopulation of hPBMCs. A Representative side scatter vs. forward scatter plot of hPBMCs representing populations of lymphocytes (L), granulocytes (G) and monocytes (M). B&C Expression of OPN receptors (αvβ3 (B) and CD44v6 (D)) was measured in hPBMCs and was evaluated in L vs. GM subsets. D Transwell migration assay in L vs. GM subset indicated that only the latter is capable of migrating toward OPN thus providing a functional relevance of expression of receptors.
