Co-infusion of adipose tissue derived mesenchymal stem cell-differentiated insulin-making cells and haematopoietic cells with renal transplantation: a novel therapy for type 1 diabetes mellitus with end-stage renal disease.

Type 1 diabetes mellitus (T1DM) is a common cause of end-stage renal disease (ESRD). Various factors contribute to wide fluctuations in blood glucose levels and exogenous insulin requirement in such patients even after renal transplantation (RT). Simultaneous pancreas-kidney transplantation is one of the therapies for these patients. Stem cell (SC) therapy for T1DM and for minimisation of immunosuppression after RT has shown encouraging results. We report a 30-year-old-man with T1DM since 15 years and ESRD since 2 years, who underwent living donor RT and co-infusion of in vitro generated insulin-making cells differentiated from donor adipose tissue derived mesenchymal stem cells and bone marrow -derived haematopoietic SC into subcutaneous tissue, portal and thymic circulation under non-myeloablative conditioning. Over follow-up of 13 months he has stable graft function with serum creatinine, 1.2 mg/dl, zero rejection and glycosylated haemoglobin level of 6.1% on calcineurin-inhibitor based therapy......
