Lung transplantation in wild-type mice. A, C3H → B6 lung grafts on postoperative day 3. B, Division of adoptively transferred CFSE-labeled CD45.1+ T cells in lung grafts, contralateral lungs (C. Lung), draining lymph nodes (LN) and spleen 3 days after C3H → B6 lung transplantation. C, Division of adoptively transferred, CFSE-labeled CD44lowCD45.1+ T cells 3 days after C3H → B6 lung transplantation. D, Division of T cells injected on postoperative day 4 and analyzed 3 days later after C3H → B6 lung transplantation. E and F, C3H → B6 (E) and B6 → B6 (F) lung grafts on postoperative day 7. G, Division of T cells injected on day 0 and analyzed in lung grafts on postoperative day 3 after B6 → B6 transplantation. Data are representative of at least three independent experiments.
