[Clinical research on reconstitution of CD4+CD25+ T cells after haploidentical bone marrow transplantation].

The aim of this study was to investigate the reconstitution of CD4(+)CD25(+) T cells after haplo-identical bone marrow transplantation (hiBMT) and its correlation with graft versus host disease (GVHD) and relapse. Peripheral blood samples from 27 patients after hiBMT were harvested and the percentage and absolute counts of CD4(+)CD25(+) T cells were detected by flow cytometry. The correlations of GVHD occurrence and disease relapse with the reconstitution of CD4(+)CD25(+) T cells were analyzed.
