Profiles of TCRβ repertoire diversity before and after AHSCT. Profiles are shown for a patient with pretransplantation sjTREC level of more than 1200 copies/mL blood (A) and a patient with pretransplantation sjTREC level fewer than 1200 copies/mL blood (B). Profiles are shown before AHSCT (Ai, Bi), 1 month after AHSCT (Aii, Bii), and 6 months after AHSCT (Aiii, Biii).
