| 摘 要： | 目的:研究外源性Gli1抑制剂GANT61对小鼠磨牙胚体外发育的影响。方法:采用小鼠磨牙胚体外培养系统,运用体视镜、组织学HE染色方式观察小鼠磨牙胚被Gli1抑制剂GANT61影响后的发育情况,并对牙胚构成部分进行测量。结果:在Gli1抑制剂GANT61作用下,实验组相对于对照组出现下磨牙牙胚发育速度减慢,成釉器凹陷且形态不规则,内釉上皮细胞呈现不规则排列,成釉器大小在高浓度GANT61组明显变小。结论:Gli1抑制剂GANT61可能通过扰乱成釉器的发育阻碍胎鼠磨牙胚的发育过程。

| Abstract: | Objective:To study the effect of Gli1 inhibitor GANT61 on tooth development in mice.Methods:The mouse molar germ in culture system was observed with stereoscope and histology after being affected by the Gli1 inhibitor GANT61,and the size of the tooth germ was measured.Results:Histological analysis showed that the degree of GANT61 treated group’s development was slower compared with that in the control group.Furthermore,the enamel organ was irregular in shape,and the inner enamel epithelial cells were irregularly arranged.The size of the enamel organ was significantly smaller in the high dose of GANT61 compared with that in the control group.Conclusion:GANT61 can block the development of molar by disturbing the development of enamel organ. |
