Morphological analysis of cementogenesis using a newly identified cementoblast specific marker

我们证实了水通道蛋白在牙骨质形成过程中的表达。大鼠磨牙脱细胞牙骨质形成过程中牙根面细胞表达水通道蛋白。免疫组化鉴定这些细胞为成牙骨质细胞。在牙槽骨发育过程中，水通道蛋白在牙周膜与牙槽骨界面细胞上表达。这些细胞具有与成牙骨质细胞不同的形状，并具有翼状突起。这些结果表明，aquapolin在牙周组织的发育过程中起着重要的作用。

We demonstrated the expression of aquaporin during cementgenesis. Cells on the developing root surface expressed aquaporin in rat molars during acellular cementgenesis. We immuno-histochemicaly identified these cells as cementblasts. The expression of aquaporin was observed on the cells on the interface between periodontal ligament and alveolar bone during alveolar bone development. These cells showed the different shapes from cementoblasts and possessed wing-like projections. These results suggest that aquapolin plays an important role during the development of periodontal tissue.
