摘要
胶原蛋白 X 是一种细胞外基质蛋白,通常存在于注定要矿化的肥大软骨中。它与哺乳动物硬组织的矿化过程密切相关,特别是调节基质成分的分区。尽管牙齿的牙本质矿化程度很高,但以前却没有任何报道表明这种结缔组织中存在胶原蛋白 X。在这里,我们首次根据微观形态学和免疫组化数据报告了哺乳动物牙本质中胶原蛋白 X 的存在。我们推测,牙本质中的胶原蛋白 X 可能会长期阻止矿化前沿向牙髓中未被矿化的软组织成分发展。
The first report of the presence of collagen X in mammalian dentinal matrix
Collagen X is an extracellular matrix protein, usually found in the hypertrophic cartilage destined to be mineralized. It is intimately associated with the mineralization process of the mammalian hard tissues, and particularly, regulating the compartmentalization of matrix components. Despite the fact that the dentine of the tooth is highly mineralized, there are no previous reports to indicate the presence of collagen X in this connective tissue. Here we report, for the first time, its presence in mammalian dentine based on micromorphological and immunohistochemical data. We hypothesize that the collagen X in dentine may in the long term arrest the progression of the mineralization front towards the soft tissue components of the pulp that are not destined to be mineralized.
期刊介绍:
Morphologie est une revue universitaire avec une ouverture médicale qui sa adresse aux enseignants, aux étudiants, aux chercheurs et aux cliniciens en anatomie et en morphologie. Vous y trouverez les développements les plus actuels de votre spécialité, en France comme a international. Le objectif de Morphologie est d?offrir des lectures privilégiées sous forme de revues générales, d?articles originaux, de mises au point didactiques et de revues de la littérature, qui permettront notamment aux enseignants de optimiser leurs cours et aux spécialistes d?enrichir leurs connaissances.
