科学家开启人造心脏:跟真实一样能跳动

2018-11-14 09:46:37   快科技 

心脏病一直都是人类健康的一大杀手,每年因为这个疾病去世的不在少数。

据德国媒体报道称,该国的研究人员已经在实验室培育出人类心脏组织肌条。这些利用人类诱导多功能干细胞培育成的组织不仅能够正确表达基因,而且其伸缩跳动也和真实心房组织一样。

换句话说,科学家已经培养出了心脏组织,其伸缩跳动也和真实心房组织一样,而目前他们还在致力于研究如何利用实验室培育的心脏组织开发治疗心房纤颤的药物。

现阶段科学家依然在努力的方向是,人类诱导多功能干细胞(hiPCSs)始于人体内的成体细胞,将这些细胞恢复到干细胞阶段,就可以培育成任何组织类型。

研究人员Marta Lemme表示:“这些心房肌条能够模拟心房颤动,也有助于测试药物。尽管如此,仍然可以做出改进,使其与人类心房组织更接近。对我们来说,下一步是测试各种诱发心律失常的方法,研究心房颤动电重构的机制,并测试新的潜在药物。”
