However, the efficiency of mobilization varies among donors, and suboptimal mobilization may require additional collection procedures or rescue strategies.\n\nThis prospective, multicenter, randomized trial evaluates whether the timing of daily G-CSF administration (morning vs evening) affects the level of circulating CD34+ cells prior to apheresis in healthy donors. Participants will be randomly assigned to receive subcutaneous G-CSF 10 μg\u002Fkg once daily for 5 consecutive days either at 08:00 (±15 minutes) or at 20:00 (±15 minutes). The primary endpoint is the peripheral blood CD34+ cell count measured approximately 12 hours after the last G-CSF dose and within 60 minutes before the start of the first apheresis session. Secondary endpoints include collection efficiency and CD34+ yield metrics, the proportion of donors achieving the target CD34+ dose on the first collection day, the need for a second collection day, and donor safety outcomes.\n\nThe goal of the study is to identify a practical dosing schedule that may improve stem cell mobilization and streamline donor collection procedures.",[28],"Granulocyte Colony-Stimulating Factor (G-CSF) Mobilization",[30,31,32],"CD34","G-CSF","Allo-HSCT","RECRUITING","2026-06-25",{"date":36,"type":37},"2026-06-29","ACTUAL",{"date":39,"type":37},"2026-03-01",{"date":41,"type":22},"2027-03-30",{"name":43,"class":44},"First Affiliated Hospital of Zhejiang University","OTHER",3,""]
