通过机器灌注使捐赠的肝脏在生物学上变得更年轻

科学家们发现，放置在机器灌注系统中的捐赠肝脏在生物学上似乎变得更年轻。研究人员使用表观遗传学和基因表达的“衰老时钟”发现，即使在时间上更老的肝脏，经过灌注后，其生物年龄也比储存在冰上的肝脏低。这种效应表明灌注可以将生物衰老逆转约30%，这可能解释了为什么灌注的器官在移植后表现更好，并可能带来改进的器官利用和修复策略。 AI

捐赠的肝脏可以变得更年轻

Once an organ is removed from a donor’s body, the clock starts ticking. Surgeons usually flush the organ with a preservative solution, bag it, and put it on ice—where it immediately starts to degrade. The team has a matter of hours to get it into a recipient’s body. There’s anoth…
