Article Abstract

In this review, the authors outlined concepts and strategies to achieve immune tolerance through inducing hematopoietic chimerism after solid organ transplantation and introduced challenges and opportunities in harnessing two-way alloresponses to improve outcomes after intestinal transplantation (ITx). Next, the authors discussed the dynamics and phenotypes of peripheral blood and intestinal graft T-cell subset chimerism and their association with outcomes. The authors also summarized studies on other types of immune cells after ITx and their potential participation in chimerism-mediated tolerance. The authors further discussed strategies and future directions to promote chimerism-associated tolerance after ITx to overcome rejection and minimize immunosuppression.

Compelling experimental evidence confirms that the robustness and longevity of mixed chimerism (MC) relies on the persistence and availability of donor-derived hematopoietic stem cell (HSC) niches in recipients. Based on our prior work in rodent vascularized composite allotransplantation (VCA) models, we hypothesize that the vascularized bone components in VCA bearing donor HSC niches, thus may provide a unique biologic opportunity to facilitate stable MC and transplant tolerance. In this study, by utilizing a series of rodent VCA models we demonstrated that donor HSC niches in the vascularized bone facilitate persistent multilineage hematopoietic chimerism in transplant recipients and promote donor-specific tolerance without harsh myeloablation.

Measurement of chimerism in cynomolgus monkeys using human-specific short tandem repeat-based assay.

Preclinical testing of a mixed chimerism mediated organ transplant tolerance strategy, in a cynomolgus macaque model, would be facilitated by the establishment of a reliable technique for quantitative assessment of chimerism. Among various techniques used for measurement of chimerism in humans, microsatellite DNA profiling has been considered the most versatile one that can discriminate between two individuals. We adopted a commercially available short tandem repeat profiling methodology to cynomolgus monkeys using two human specific alleles, TPOX and CSF1PO.
