Immunohistochemical stuby of the repaired joint arising from transplanting the articular disk in the sternoclavicular joint to the temporomandibular joint.

在这项研究中，我们用彩色图像系统阐明了弹性纤维和氧他兰纤维在人胸锁关节[SCJ]中的分布，并用免疫过氧化物酶染色阐明了细胞外基质中弹性纤维和羟基塔兰纤维的分布。细小弹力纤维散在分布于胸锁骨盘纤维层。该关节盘由位于SCJ关节盘胸骨侧的胶原束和位于关节盘锁骨侧的包括结缔组织在内的细胞组成。视盘厚度由下到上逐渐增加。I、III、V型胶原纤维及其他细胞外基质在SCJ的锁骨、胸骨肥大带及关节的结缔组织中均有表达。颈椎关节盘面的细胞活性高于胸骨表面。

In this study, we clarified the distribution of elastic and oxytalan fibers in a human sternoclavicular joint [SCJ] using a color image system and in extracellular matrices using immunoperoxidase staining. Fine elastic fibers [EFs] were scattered in the fibrous layr of the sternoclavicular disk. This articular disk was composed of a collagenous bundle on the sternum side of the articular disk in the SCJ and cellular components including connective tissue on the clavicular side of the articular disk. The thickness of the disk gradually increased from the inferior to superior portion. Collagen fibers type I,III and V and other extracellular matrices [ECMs] were detected in the hypertrophic zone in the clavicular and sternum side of the SCJ and in the connective tissue of the articulatio condylar. On the cervical surface of the articular disk, cellular activity was higher than on the sternum surface.
