E-ros + Ceprate indicates sheep red blood cell rosetting plus positive selection of CD34+ cells with use of Ceprate SC columns; MACS, magnetically activated cell sorter; and GVHD, graft-versus-host disease.
G-CSF was given in a dosage of 5 μg/kg of body weight daily for the first 20 days after transplantation.
CD3+ T cells contained the same proportion (50%-70%) of CD4+ cells in the two series.
There were no significant differences between patients receiving G-CSF and those not receiving G-CSF (P = .34) as determined 270 days after transplantation.
