(A) Migration of CD34 cells from a peripheral blood stem cell harvest over 16 hours at 37°C through filters coated with H120 15 μg/mL and BSA with and without a mixture of SCF 100 ng/mL, IL-3 10 ng/mL, G-CSF 500 ng/mL, and IL-6 200 U/mL. Migration was increased with H120 compared with BSA (P = .01) in the presence of growth factors. (B) Migration of CD34 cells over 16 hours through filters coated with BSA, H120, and H0 at 15 μg/mL with the mixture of growth factors used in (A). Migration was increased with H120 compared with BSA (P < .001) and H0 (P < .001).
