用激光使牙齿再生

试想用一种简单的激光治疗就能令一只破碎牙齿的一部分重新生长。能使牙齿重新生长可让补牙、人造牙冠、及令人不舒服的牙科就诊成为过去。

研究人员通过搞清楚如何刺激牙本质的生长而向这一场景又接近了一小步。

牙本质是构成牙齿的坚硬、钙化的组织。zui近有一大堆的专注于操纵干细胞来刺激组织再生的研究。这些研究中的大多数聚焦于从外部改变干细胞的技术，例如，通过输送生长因子或使用某种细胞外基质。

在此，哈佛医学院等机构的研究人员希望看到他们是否能通过激活已经在身体内的生长因子而不是通过添加外部的因子或材料来操纵干细胞。牙本质组织（它比骨头更硬但比牙釉质软）组成了牙齿的核心。当某个牙齿出现豁缺或损坏，牙科医生会用陶瓷或其它合成材料来保护牙齿（如补牙用填充物质、人造牙冠及牙齿贴片等）。

研究发现，在大鼠中，激光可令一块失去的牙齿结构再生。研究人员用钻头在大鼠的牙齿结构中制造了一个缺损并去除了一块牙本质。他们接着对暴露的牙齿结构及其下方的软组织用激光照射。12 周后，该小组观察到，新的牙本质已经形成。原来，激光激活了一种叫做TGF-β的生长因子，后者可刺激干细胞再生出牙本质。

研究人员表示，由于TGF-β存在于许多组织（如皮肤和骨）中，而且它已知在控制组织炎症中颇为重要，因此这一技术可能被应用于身体的其它部位。眼下，研究人员专注于在人群中测试牙本质的再生。
