FL plasma levels correlate with DC1/DC2 reconstitution after SCT. (A) Levels of FL (○), G-CSF (⋄), GM-CSF (▵), and SCF (□) in PB of patients on days 7, 14, and 30 after SCT, as determined by ELISA. The mean value (bars) and SEM is indicated. (B-D) Correlation between numbers of circulating DC1 and DC2 on day 14 in individual patients and day 7 plasma levels of FL, G-CSF, and SCF, respectively. Solid line shows the correlation.
