The method, which was developed in Newcastle, should help women like Sharon Bernardi, from Sunderland, who lost all seven of her children to mitochondrial disease.
这一技术诞生于英国纽卡斯尔,将帮助像来自桑德兰市的莎伦•博纳迪这样的女性,她的七个孩子都死于线粒体疾病。
Ms Bernadi said was "overwhelmed" by the decision.
博纳迪太太表示,她获悉这一决议通过时欣喜万分。
Mitochondria are the tiny compartments inside nearly every cell of the body that convert food into useable energy. They have their own DNA, which does not affect characteristics such as appearance.
线粒体是可将食物转化为可用能量的小“隔间”,几乎存在于身体所有细胞中。它们拥有自己的DNA,这些DNA不会影响外貌等特征。
Defective mitochondria are passed down only from the mother. They can lead to brain damage, muscle wasting, heart failure and blindness.
