| Research Abstract |
(AIMS)We investigated that transduction of the human Interleukin-10 (IL-10) gene in mouse foetal liver stem cells (hIL-10-TFLs) protects them from rejection in an allogeneic host and the effects of these cells in organ transplantation.(METHODS)Balb/c mice were sublethally irradiated before receiving vascularized heterotopic heart grafts from C57BL/6 mice. TFLs from C57BL/6 mice transduced with hIL-10, were injected on the day of transplantation, every 20 days.(RESULTS)Heart transplants survived 86.25 versus 46.3 or 11.5 days, in mice which received repeated injections, a single injection, or in control mice. Expressions of H-2b and hIL-10 were found in thymus, liver. Foxp3+ cells present inside the transplanted heart.(CONCLUSIONS)We have shown that repeated injections of hIL-10-TFLs are efficient in impairing transplant rejection. This"prope tolerance"was associated with survival of donor haematopoietic cells in the host.
