了解牙齿再生和更新背后的细胞和分子机制已成为人们非常感兴趣的话题,而小鼠切牙为这些过程提供了一个模型。这个非凡的器官在动物的一生中不断生长,并从位于唇部(朝向嘴唇)和舌部(朝向舌头)颈环(CL)区域的成体干细胞活动池中产生所有必要的细胞类型。只有来自唇侧CL的牙齿干细胞才能产生成釉细胞,成釉细胞在唇侧表面产生釉质,即牙齿的外层覆盖物。这种不对称的釉质形成允许门牙尖端的磨损,而近侧切牙中的祖细胞和干细胞确保牙齿组织不断补充。在体外分离和培养这些祖细胞或干细胞的能力允许它们的扩增,并为许多在体内无法实现的实验打开了大门,例如对潜在干细胞调节因子的高通量测试。在这里,我们描述和展示了一种可靠和一致的方法来培养小鼠切牙唇侧CL的细胞。
Understanding the cellular and molecular mechanisms that underlie tooth regeneration and renewal has become a topic of great interest, and the mouse incisor provides a model for these processes. This remarkable organ grows continuously throughout the animal's life and generates all the necessary cell types from active pools of adult stem cells housed in the labial (toward the lip) and lingual (toward the tongue) cervical loop (CL) regions. Only the dental stem cells from the labial CL give rise to ameloblasts that generate enamel, the outer covering of teeth, on the labial surface. This asymmetric enamel formation allows abrasion at the incisor tip, and progenitors and stem cells in the proximal incisor ensure that the dental tissues are constantly replenished. The ability to isolate and grow these progenitor or stem cells in vitro allows their expansion and opens doors to numerous experiments not achievable in vivo, such as high throughput testing of potential stem cell regulatory factors. Here, we describe and demonstrate a reliable and consistent method to culture cells from the labial CL of the mouse incisor.
