目的
2
研究Pax6和Wnt7a在碱烧伤小鼠角膜中的表达,探讨Pax6和Wnt7a是否参与了角膜的损伤修复。
方法
2
选取40只健康雌性昆明小鼠,随机分为对照组和实验组,每组20只。实验组小鼠右眼建立角膜碱烧伤模型,左眼不做任何处理。对照组小鼠不做碱烧伤。1个月后,取小鼠角膜组织,HE染色观察角膜的形态学变化;免疫荧光染色及流式细胞术检测角膜组织中p63、Pax6和Wnt7a的表达。
结果
2
肉眼观察到碱烧伤模型小鼠角膜混浊,HE染色观察可见角膜内有杯状细胞和毛细血管增生。实验组小鼠角膜厚度较对照组显著增加(
P
<
0.05)。与正常小鼠的角膜相比,碱烧伤小鼠角膜Pax6阳性表达率降低(
P
<
0.05),而Wnt7a阳性表达率升高(
P
<
0.05)。
结论
2
Pax6及Wnt7a在碱烧后小鼠的角膜中表达量发生改变,提示可能参与了角膜的损伤修复。
Objective
2
To explore the expression of Pax6 and Wnt7a in alkali-burned cornea of mice, and thus discuss whether Pax6 and Wnt7a are involved in the repair of corneal damage.
Methods
2
Totally 40 healthy female Kunming mice were randomly divided into the control group and the experimental group,with 20 mice in each group.The alkali burn model was established in the right eye of mice in the experimental group,and the left eye was not treated. The control group was not intervened by alkali burn. One month later, corneal tissues of mice were taken and the morphological changes of the cornea were observed by HE staining. The expressions of p63, Pax6 and Wnt7a in corneal tissues were detected by immunofluorescence staining and flow cytometry.
Results
2
Corneal opacity was observed with the naked eye in the alkali-burned mice. HE staining revealed goblet cells and capillary hyperplasia within the cornea. The corneal thickness of the mice in the experimental group was significantly increased than that in the control group (
P
<
0.05). Compared with the corneas of normal mice, the positive expression rate of Pax6 in the corneas of alkali-burned mice decreased (
P
<
0.05), while the positive expression rate of Wnt7a increased (
P
<
0.05).
Conclusion
2
The expression levels of Pax6 and Wnt7a changed in the corneas of mice after alkali burn, suggesting that they might be involved in the repair of corneal damage.
