第2673期:Tooth grown in laboratory by scientists

Researchers from King's College and Imperial College developed a material that mimics the environment needed for tooth development, allowing cells to send signals and begin forming a tooth. 伦敦国王学院和帝国理工大学的研究人员研发出了一种模拟牙齿生长环境的材料，这种材料可以促使细胞发出信号并开始形成牙齿。 

The idea is that the lab-grown teeth would naturally regenerate and integrate into the jaw, creating a new set that's stronger and far more durable than traditional fillings or implants. 这项研究的想法是让实验室培育的牙齿能够自然地再生并与颌骨结合在一起，从而长出一套更坚固的新牙，其耐用度也会优于补牙用的传统填充材料或种植牙。 

It could take years before these lab-grown teeth are seen in the mouths of dental patients. But scientists say once they discover how to do it, it will revolutionise oral health. 我们可能还需要很多年时间才能看到这种在实验室中培育的牙齿被应用于牙科患者的口腔中。但是科学家们表示，一旦他们研究出应用方法，此项技术就将彻底改变口腔健康。
