Migration and expansion of donor T cells occurred independently of non-T donor splenocytes and vice versa. (A) Lung, (B) liver, (C) spleen, and (D) femur. B10.BR mice were lethally irradiated and given C57BL/6 BM with either whole splenocytes or TCD splenocytes or purified T cells from eGFP Tg C57BL/6 mice. Tissues from 1 of 3 representative mice from each time point per group are shown. Stereomicroscope was set to 8.0 × (lung, liver, spleen) and 10.0 × (femur) zoom factor with a 0.63 × transfer lens.
