肝细胞生长因子(HGF)被认为是早期器官发生过程中上皮间质相互作用的介质之一,也参与了小鼠磨牙的发育。在发育中的牙齿中,HGF在牙乳头细胞中表达,其受体c-Met在牙上皮细胞中表达。为了研究HGF在牙齿发育中的作用,我们在体外培养的E-14磨牙上检测了反义硫代磷酸寡脱氧核苷酸对HGF翻译抑制的影响。并对体外培养的转基因met E-14磨牙的组织形态发生和牙冠细胞分化进行了分析。3D重建显示尖点模式的扰动。然而,组织形态发生和冠细胞分化是正常的组织学水平。
Hepatocyte growth factor (HGF) is considered to be one of the mediators of epithelio-mesenchymal interactions during early organogenesis and to be also involved in the development of murine molars. In the developing tooth, HGF is expressed in the cells of the dental papillae, and c-Met, its receptor, in the cells of dental epithelia. In order to study the functional role played by HGF in tooth development, we tested the effects of HGF translation arrest by anti-sense phosphorothioate oligodeoxynucleotides on E-14 molars cultured in vitro. We also analyzed the histo-morphogenesis and crown cytodifferentiation of transgenic met E-14 molars cultured in vitro. 3D reconstructions revealed perturbations of the cusp pattern. However, histo-morphogenesis and crown cytodifferentiation were normal at the histological level.
