Mobilization of leukocytes and CD34⁺ cells during G-CSF administration.

Daily WBC and CD34⁺ count during G-CSF mobilization. Arrowheads indicate the day apheresis started. Solid horizontal line represents target CD34⁺ cell count of 6 CD34⁺cells/μL required to undergo apheresis. Two patients did not achieve the target CD34⁺ cell count and did not undergo apheresis.
