移植了一颗猪的心脏后,那只狒狒多活了195天

2018-12-12 10:35:32   网易科技 

研究人员已经成功为狒狒进行了革命性的跨种族移植手术,其中一只狒狒植入猪心脏后存活了6个月时间。这个过程被称为异种器官移植,指的是一个物种的器官被移植给另外一个物种。专家们希望这项技术未来有一天能够解决全球器官捐赠严重短缺的困境。

这只移植了猪心脏的狒狒成功存活了195天,这也让科学家们更接近于在人类身上进行猪器官移植实验。慕尼黑大学Bruno Reichart带领的科学家团队首先对捐赠心脏的猪进行了基因改造,这样它们的心脏组织就不会携带猪心脏的特征。这样做也会让狒狒的免疫系统不会把心脏视作外来物体而产生排斥反应。

在研究中,来自德国、瑞典和瑞士的研究人员为5只狒狒移植了猪心脏。其中一只狒狒手术后不久去世,另外两只存活了3个月时间。剩下的两只去世前分别存活了195天和182天。由于全球器官捐献的严重短缺,这项研究对于医疗领域来说可能意味着巨大的突破。猪是人类进行器官移植的理想候选者,因为它们的器官,特别是心脏和肾脏与人类的器官非常相似。

研究团队在发表于《自然》杂志的论文中写道:“移植的猪心脏连续工作了长达195天,这对于心脏异种移植的临床应用是一项里程碑式的突破。在过去长达25年的研究中,接受猪器官异种移植后的狒狒,最大生存限度只有57天,而且据我们所知只有一次达到了这一限度。”

但是专家认为这项研究尚未完成。英国心脏基金会的Jeremy Pearson教授称:“这项最新研究让我们更接近于将猪心脏移植到人类身上。但是在第一例猪心脏移植给人类之前,仍然需要进行更广泛而且更长期的研究。”

他并未参与到这项研究中,但是他认为:“在人类身上进行异种移植需要严肃对待,研究人员必须证实它们比人造心脏更加成功,并且确保心脏移植不会将病毒传递给器官接受者,引发潜在的安全隐患。”
