Abstract:

Copine 7(CPNE7), a calcium phospholipid-binding protein found in preameloblast-conditioned medium(PACM), is initially expressed and secreted by dental epithelial cells. CPNE7 plays an important role in the differentiation of dental mesenchymal cells to odontoblasts. Recently, accumulating evidence has demonstrated that CPNE7 can induce the tertiary dentin formation and reduce the permeability of dentin by promoting mineral deposition in dentinal tubules, which allows CPNE7 to be applied in dentin repair. Besides, CPNE7 has shown positive effects on cementogenesis, but has no obvious relationship to the formation of periodontal ligament(PDL). In this study, we summarized research progress of the roles and mechanisms of CPNE7 in the development of dentin and periodontium, offering new approaches to treating related diseases.

Key words: Copine 7, dentin, periodontium, tissue regeneration, CPNE7 derivative
