CXCR4 expression.

(A) Expression of CXCR4 and CD33 antigens on freshly purified G-CSF mobilized CD34⁺ progenitors from a representative experiment. Markers were set according to isotypic controls. The percentage of cell coexpressing both antigens is indicated. (B) CXCR4 expression on freshly purified CD34⁺CD105⁺ and CD34⁺CD105⁻ cell fractions from a representative experiment. Markers were set according to isotypic controls. (C) CXCR4 expression during unilineage E, GM, and Mk differentiation. Markers were set according to isotypic controls. The percentage of cells coexpressing CXCR4 and glycophorin-A, CD33, or CD61 differentiation antigens is indicated.
