Spatiotemporal expression pattern of Fibulin-7 in the development process of murine mandibular first molars

doi:10.19438/j.cjoms.2017.05.001

Abstract

Abstract: PURPOSE: To investigate the expression patterns of Fibulin-7 in murine tooth germs of mandibular first molars at early developmental stages. METHODS: Mandible samples of C57BL/6J mice of embryonic day 15.5, postnatal day 1 and day 7 were collected. The expressions of Fibulin-7 in murine mandibular first molar germs were detected by immunohistochemistry staining. RESULTS: The expression of Fibulin-7 was detected and gradually increased from late bell stage till maturation of tooth germs in mandibular first molars. CONCLUSIONS: Fibulin-7 was expressed at different stages through the development of tooth germs, indicating their individual functions in the process of mesenchymal cells into odontoblasts and the formation of pulp-dentin complex.
