T cells are oligoclonal in subject 1 before transplantation but are polyclonal after transplantation in both subjects by flow cytometry. TCR diversity for CD4 (A) and CD3 (B) T cells was assessed for subject 1 before transplantation. (C) The latest diversity assessment in subject 1 is shown; (D) the latest assessment in subject 2 is shown. Note that the y-axis in the CD4 in panel A differs from the y-axis in CD4 panels C-D. (A,C-D) The shaded area represents the normal range ± 3 SD based on data from 19 healthy adults.
