Analysis of circulating Vβ TcR repertoire after transplantation with FACS-sorted autologous CD34⁺ HPC versus a healthy donor. (A) Percentage of CD3⁺ peripheral T cells that express a given Vβ TcR at 3 weeks, 5 weeks, 3 months, 6 months, and 1 year after transplantation for patient #2. (B) Percentage of CD3⁺ peripheral blood T cells that express the same Vβ TcRs over time in a healthy donor. The frequencies of Vγ9 and Vδ2 were identical and are shown using the same symbol.
