Abstract (original English)

Transplantation tolerance is still a Utopian dream for many transplanters. Mesenchymal stem cells (MSC) have shown immuno-modulatory and tolerogenic effects in experimental models. We present a 29-year-old male with end stage renal disease (ESRD) who was transplanted with HLA 4/6 matched kidney from 51-year-old father in June 2010 preceded by co-infusion of donor-adipose tissue derived mesenchymal stem cells (AD-MSC) and bone marrow derived hematopoietic stem cells (BM-HSC) under non-myeloablative conditioning for deleting rejecting T and B-cells. He has maintained fairly stable graft function with serum creatinine (SCr) between 1.5 and 1.8 mg/dL at 3 years post-transplant with absence of donor specific antibodies (DSA), normal protocol graft biopsy, and peripheral T-regulatory cell levels (pTregs) (CD127(low/-)CD25(high)CD4+) of 4.57% on zero immunosuppression since 6 months.
