Abstract

In this issue, Sobrino et al. present a case of hematopoietic chimerism and subsequent tolerance after isolated kidney transplantation in a pediatric patient with syndromic combined immune deficiency. This report not only highlights the chimerism approach for tolerance induction in transplantation, but it is also the first evidence of hematopoietic stem cells in human kidneys. This commentary discusses the potency and risks of the chimerism approach for tolerance induction after solid organ transplantation, especially in (pediatric) patients with immune deficiencies.
