Broader clinical application of reconstructive hand and face transplantation is hindered by the need for lifelong immunosuppression for allograft maintenance. In this review, we summarize various cell-based approaches to tolerance induction currently under investigation in both clinical and pre-clinical models to alleviate the need for chronic immunosuppression. These include strategies to induce mixed hematopoietic chimerism, therapy with T and B regulatory cells, regulatory macrophages, tolerogenic dendritic cells, and mesenchymal stem cells. The vascularized, intragraft bone components inherent to reconstructive transplants serve as a continuous source of donor-derived hematopoietic cells, and make hand and face transplants uniquely well suited for cell-based approaches to tolerance that may ultimately tilt the risk-benefit balance for these life-changing, but not life-saving, procedures.
