Thymic reconstitution is not dependent on the stem cell source employed or GvHD occurrence. Mean (±SE) number of log10 TREC was measured by quantitative PCR, before, and 3 and 6 months after transplantation in patients that received either a haploidentical hematopoietic Stem Cell Transplantation (Haplo, N = 33) or a Cord Blood Unrelated Donor Graft (CB, N = 24). Signal Joint (sj) TREC were quantified in (A,C,E, and F) and betaTREC in (B and D). Results were expressed by 150,000 Peripheral Blood Mononuclear Cells in (A and B) and by μL of blood in (C,D,E, and F). Patients were subsequently subdivided according to GvHD occurrence (E and F).
