自1974年Slavkin和他的合作者提出牙骨质的上皮起源以来,已经进行了许多实验来提供牙釉质相关蛋白沿着牙根表面沉积的证据。然而,釉原蛋白和其他蛋白质都没有完全满足期望。在以前的研究中,我们已经确定了一种新的mRNA编码的细胞外样蛋白,我们称之为amelin。它在大鼠磨牙和切牙的分泌期和分泌后成釉细胞中高水平表达。本研究中描述的原位杂交实验还将amelin信息定位到邻近根端新沉积牙本质外周表面的上皮细胞以及嵌入臼齿细胞牙骨质中的细胞。在切牙中,amelin RNA阳性细胞在牙骨质形成开始的区域被检测到。在牙根表面的细胞中未发现釉原蛋白RNA信号。我们推测根鞘上皮细胞和成釉细胞都在合成釉蛋白,釉蛋白可能是参与牙骨质形成的关键蛋白之一。(J Bone Miner Res 1996;11:892 - 898)
Since 1974, when Slavkin and his collaborators proposed the epithelial origin of cementum, many experiments have been carried out to provide evidence for deposition of enamel‐related proteins along the root surface. However, neither amelogenin nor other proteins have fully satisfied expectations. In previous studies, we have identified a novel mRNA coding for an extracellular‐like protein which we called amelin. It was expressed at high levels in secretory and postsecretory ameloblasts in rat molars and incisors. In situ hybridization experiments described in the present study also localized the amelin message to epithelial cells adjacent to the peripheral surface of newly deposited dentin in the root end and to cells embedded in cellular cementum in molars. In incisors, the amelin RNA positive cells were detected in the area where cementum formation had been initiated. No amelogenin RNA signal was found in the cells at the root surface. We postulate that the epithelial cells of the root sheath as well as the ameloblasts are synthesizing amelin which might be one of the key proteins coupled to the process of cementogenesis.
