SSUH2在小鼠牙胚发育中的时空表达
|
Abstract:
摘要 目的:探讨牙本质发育不良I型(dentin dyspepsia type I,DD-I)相关致病基因Ssuh2在小鼠牙胚发育各个时期中的作用。方法:采用HE确定小鼠下颌第一磨牙牙胚发育E13.5d、E14.5d、E16.5d、P2.5d、P7d的时期,采用免疫组化法观察SSUH2在各个时期的表达分布。结果:蕾状期(E13.5d),SSUH2在上皮细胞和间充质细胞均呈阳性表达;帽状期(E14.5d)和钟状早期(E16.5d),SSUH2均在基底膜、内、外釉上皮层、釉结、颈环呈强阳性表达。细胞分化及分泌期(P2.5d)和矿化期(P7d),SSUH2均在成釉细胞、成牙本质细胞、牙釉质、上皮根鞘中呈强阳性表达。结论:SSUH2在小鼠牙胚发育中均有表达,且各个时期略有差异,SSUH2可能参与小鼠的牙胚发育
