Plasma level of SDF1.

(A) In SCID mice, the concentration of human SDF1 was measured throughout the study in the plasma of AdSDF1-treated (○) or AdNull-treated mice (●). All data are expressed as the mean (n = 4) ± SEM. (B) In SCID mice, the concentration of human SDF1 was measured in the plasma (▪) and BM (■) of AdSDF1-treated mice 3 days and 5 days after vector administration. All data are expressed as the mean (n = 5) ± SEM. The result from SDF1 level of BM compared to level of plasma achieves statistical significance (*P < .005).
