We selected T regulatory cells (Tregs) from standard leukapheresis using double-negative selection (anti-CD8 and anti-CD19) followed by positive selection (anti-CD25) and 72 procedures were performed. A median of 263 x 10(6) cells (range 143-470 x 10(6)) were recovered with a mean of CD4(+)/CD25(+) cells of 94.5 +/- 2.4% (36.5 +/- 18.6% CD4(+)/CD25(+hi)). FoxP3(+) cells were equal to 79.8%+/- 22.2. CD127(+) cells were 12.5%+/- 8.2. The inhibition assay showed an inhibition rate of 67 +/- 22. Cells isolated by means of this approach can be used in allogeneic hematopoietic stem cell transplantation to reduce the incidence and severity of GvHD without bystander inhibition of general immunity.
