Effect of postgrafting administration of G-CSF on CD4⁺ cell recovery in HLA-mismatched recipients of hematopoietic transplants.

Shown are the time kinetics of CD4⁺ T-cell recovery in patients who received G-CSF (panel A) compared with those who did not (panel B). CD4⁺ cell counts in patients who did not receive G-CSF were significantly higher than those in patients who had (P < .0001) at all time points from day 60 after transplantation onward.
