Tissues were harvested from representative mice shown in Figure 6. Tissues from recipients of CD4+ naive T cells were harvested between day 8 and day 9. Tissues from recipients of TCD BM only and memory T cells were harvested after recipients were electively killed on day 182. Shown are individual scores of maximum scores of 12 for each target organ.
TCD BM indicates T-cell-depleted BM; ND, not determined.
