Enhanced mobilization in αM^–/– mice by fucoidan. αM^+/+ and αM^–/– mice were treated with 2 doses of fucoidan (50 mg/kg each; ▪) or PBS (□). Nucleated cells isolated from peripheral blood 6 hours after treatment were assayed for CFU-C content. Error bars represent mean ± SEM values. *P < .005; n = 5-24.
