The Stanford Medical Center Program in Multi-Organ Transplantation and the Division of Bone marrow Transplantation are enrolling patients into a research study to determine if donor stem cells given after a living related one Haplotype match kidney transplantation will change the immune system such that immunosuppressive drugs can be completely withdrawn.

Detailed Description:

The goal of this study is for the recipients of a living related kidney transplant of one HLA haplotype to be withdrawn of immunosuppressive medication and become "tolerant "to their kidney graft. The recipient will receive a conditioning regimen composed of low dose radiation to the lymphoid tissue (total lymphoid irradiation, TLI) and anti-thymocyte globulin (ATG) at the time of transplant. They will then be infused with purified "stem cell" and T-cell from their kidney donors 2 weeks after the transplant to try to achieve mixed chimerism of their white blood cells with the donor (the recipient would have a mixture some of the with blood cells of the donor and theirs in their blood). The kidney donor has to provide peripheral stem cell 6-8 weeks before kidney donation. It is an outpatient procedure done using peripheral veins after treatment with G-CSF (filgrastim).Immunosuppressive medication will be decreased gradually and possibly stopped by the end of the first year after the transplantation if the recipient meets withdrawing criteria (persistence of mixed chimerism more than 180 days, no episode of rejection and no rejection on surveillance kidney biopsy). Potential candidates need to be approved for kidney transplant and available for close follow-up at Stanford University Medical Center.
