这项研究表明,胶原蛋白是动物中最丰富的蛋白质,在牙齿,骨骼和肌腱中以纳米级形态分布。I型胶原蛋白的这一基本特征以前从未报道过,它为这种无处不在的重要生物纳米材料的纳米级结构提供了新的理解。选择牙本质、骨和肌腱组织样本是因为它们在细胞起源和功能方面的差异,以及将矿化组织与正常生理环境中缺乏矿物质的组织进行比较。形态分布存在于所有三种组织中,证实了该特征是I型胶原的基础,无论是否存在矿物质、胶原的细胞来源(成骨细胞与成牙本质细胞与成纤维细胞)、组织的解剖位置或机械功能。
This study demonstrates that collagen, the most abundant protein in animals, exists as a distribution of nanoscale morphologies in teeth, bones, and tendons. This fundamental characteristic of Type I collagen has not previously been reported and provides a new understanding of the nanoscale architecture of this ubiquitous and important biological nanomaterial. Dentin, bone and tendon tissue samples were chosen for their differences in cellular origin and function, as well as to compare mineralized tissues with a tissue which lacks mineral in a normal physiological setting. A distribution of morphologies was present in all three tissues, confirming that this characteristic is fundamental to Type I collagen regardless of the presence of mineral, cellular origin of the collagen (osteoblast versus odontoblast versus fibroblast), anatomical location or mechanical function of the tissue.
