Successful liver allografts in mice by combination with allogeneic bone marrow transplantation.
Successful liver allografts were established by combination with allogeneic bone marrow transplantation. When liver tissue of BALB/c (H-2d) or C57BL/6J (H-2b) mice was minced and grafted under the kidney capsules of C3H/HeN (H-2k) mice, it was rejected. However, when C3H/HeN mice were irradiated and reconstituted with T-cell-depleted BALB/c or BALB/c nu/nu bone marrow cells, or with fetal liver cells of BALB/c mice, they accepted both donor (stem-cell)-type (BALB/c) and host (thymus)-type (C3H/HeN) liver tissue. Assays for both mixed-lymphocyte reaction and induction of cytotoxic T lymphocytes revealed that the newly developed T cells were tolerant of both donor (stem-cell)-type and host (thymus)-type major histocompatibility complex determinants. We propose that liver allografts combined with bone marrow transplantation should be considered as a viable therapy for patients with liver disease such as liver cirrhosis and hepatoma.
