“胡桃玩旅行者的小坤坤视频”大开眼界!3胡桃玩旅行者的小坤坤视频D打印机能打印器官了?

  3D打印胡桃玩旅行者的小坤坤视频大家都已经很熟悉了,但胡桃玩旅行者的小坤坤视频你能想象用这种方法打印器官吗?在正在举办的第26届高交会上,全球首个类器官3D打印机就亮相了,我们一起去一探究竟。

  总台央视记者 张春玲:这是本届高交会上全新亮相的,由深圳清华大学研究院成果转化的全球首个3D类器官打印机。我手上的样品就是由人工培育的心脏细胞和相关的材料通过这台打印机打印出来的。未来这样的技术可以应用在药物开发、精准医疗、再生医学等多个领域。

  类器官是利用干细胞技术经体外三维培养形成的微型组织,通常由多种细胞类型组成。类器官能够最大程度模拟体内真实器官的结构和功能,因此具有广泛的医学应用前景。就像我们的打印机需要墨水,生物打印机需要的是生物墨水,它们由细胞、培养细胞生长的生物水凝胶,以及营养因子构成。它们经过生物打印机的打印,还能保持细胞的活性。打印精度可以达到0.05微升,也就是直径两三百微米。

  深圳清华大学研究院生物智能制造和活体打印研发中心副主任 陈建伟:可以替换和修复部分受损器官,我们也还在探索用体外制造人类器官来生产这种生命活性物质,比如一些肝的类器官,生产这种类似白蛋白之类的物质。

  全球首个类器官3D打印机,是清华大学团队20年的科研成果,通过跨学科交叉研究一步步实现了工程落地,目前正处在临床科研阶段。

  深圳清华大学研究院生物智能制造和活体打印研发中心副主任陈建伟:我们也想把这些技术真正去进行产业落地,能够真正惠及每一个人。(央视新闻客户端)
