In order to improve our knowledge on the vertebral development, structure and mineralization in Acipenseriformes, we undertook a study in a growth series of reared Siberian sturgeons (Acipenser baerii) using in toto clear and stain specimens, histological and ultrastructural observations, X-ray micro-tomography, and solid state NMR analyses. Scutes were also studied to compare the tissue structure and mineralization of endoskeletal and dermal skeletal elements. This study completes and clarifies previous investigations on vertebral development and architecture in sturgeons, and brings original data on the structure of (i) the perichondral bone that is progressively deposited around the vertebral elements during ontogeny, (ii) the typical cartilage composing these elements, and (iii) the scutes. In addition we provide data on the mineralization process, on the nature of the bone mineral phase, and on the growth dynamics of the vertebral elements.

为了增进我们对鲟形目动物椎体发育、结构和矿化的了解，我们对养殖的西伯利亚鲟（Acipenser baerii）生长系列进行了一项研究，采用整体透明和染色标本、组织学和超微结构观察、X射线显微断层扫描以及固态核磁共振分析。还对骨板进行了研究，以比较内骨骼和皮骨骼元素的组织结构和矿化情况。本研究完善并澄清了先前关于鲟鱼椎体发育和结构的研究，并提供了有关以下方面结构的原始数据：（i）在个体发育过程中逐渐沉积在椎体周围的软骨周骨；（ii）构成这些椎体的典型软骨；（iii）骨板。此外，我们还提供了矿化过程、骨矿物质相的性质以及椎体元素生长动态的数据。《解剖学记录》，300:437 - 449，2017年。© 2016威利期刊公司。
