项目摘要
Physiologic changes at brain death (BD) would affect the organ suitability and outcome of transplantation. We first examined whether donor BD affects early lung function and graft survival using MHC-defined CLAWN miniature swine. Up-regulation of proinflammatory cytokines as early as 6h after BD induction was observed in the BD donor associated with inflammatory cell infiltrates on 2-hour and 2-day biopsies. Moreover, graft survival using BD donor was significantly shorter compared to the non-BD donor (26 days vs 47 days). Next to establish a new strategy to reduce inflammatory change after brain death, we tried to establish porcine mesenchymal stem cells (MSC) derived from bone marrow and adipose tissue, and successfully cultured them. After confirmation of the characteristics of these cells as MSC, we evaluate whether injection of MSC to brain-dead donor contribute to improve graft function and survival using preclinical lung transplant model of miniature swine.
脑死亡时的生理变化(BD)会影响器官的适合性和移植结果。我们首先检查了供体BD是否使用MHC定义的Clawn Miniature Swine是否会影响早期肺功能和移植物的生存。在BD供体与2小时和2天的活检相关的BD供体中,在BD供体中观察到BD诱导后6H的促炎细胞因子的上调。此外,与非BD供体相比,使用BD供体的移植物存活率明显短(26天比47天)。接下来,我们建立了一种新的策略来减少脑死亡后的炎症变化,我们试图建立源自骨髓和脂肪组织的猪间充质干细胞(MSC),并成功培养了它们。在确认这些细胞作为MSC的特征后,我们评估了使用微型猪的临床前肺移植模型将MSC注射到脑死亡供体是否有助于提高移植功能和存活。
