小鼠钟状期牙胚中Frizzled蛋白的表达
Expression of Frizzled Protein in Mouse Tooth Germ at Bell Stage
摘要
Abstract
Objective To observe the expression of Frizzled protein in mouse tooth germ at bell stage and explore the possible function of Wnt/Frizzled signal molecules. Methods Mouse embryos at 17 and 19 days of gestation (E17 and E19) as well as mice postnatal day 2 (PN2) were employed in our study. The frozen sections of the first lower molar were made and indirect immunofluorescence technique was carried out on the sections. The location of Frizzled protein was observed under the fluorescence microscope. Results Frizzled protein was expressed weakly in the inner- and outer- dental epithelium at E17. At E19,the positive staining was found to distribute at the summit of both pre-ameloblasts and pre-odontoblasts. At P2,Frizzled protein was expressed strongly at the summit of ameloblasts and odontoblasts. Conclusion Wnt/Frizzled signal molecules may be involved in the differentiation of ameloblasts and odontoblasts.关键词
