摘要

移植缺血再灌注损伤(IRI)后的内皮衰竭引发炎症级联,损害同种异体移植血流并导致急性排斥反应。激活间充质干细胞(MSCs)先天免疫调节表型的培养条件可能会减弱iri介导的内皮细胞衰竭。我们假设,缺氧或炎症细胞因子的扩张启动了MSCs的免疫抑制功能,并在体外输送后改善了同种异体移植物的灌注。

Ex Vivo Primed Mesenchymal Stem Cell Therapy Prevents Endothelial Failure and Enhances Allograft Perfusion
Endothelial failure following ischemia-reperfusion injury (IRI) in transplantation triggers the inflammatory cascade, compromising allograft perfusion and contributing to acute rejection. Culture conditions that activate the innate immunomodulatory phenotype of mesenchymal stem cells (MSCs) may attenuate IRI-mediated endothelial failure. We hypothesized that expansion in hypoxia or with inflammatory cytokines primes immunosuppressive functions of MSCs and improves allograft perfusion after ex-vivo delivery.
