Abstract
INTRODUCTION: Human teeth are composed mainly of dentin, formed by the odontoblasts. Dentin matrix protein 1 (DMP1) is one of odontoblast differentiation's most important growth factors. Human DMP1 has yet to be completely identified or studied. This study aimed to clone and characterize human DMP1. MATERIALS AND METHODS: The DMP1 gene sequence was prepared and cloned by transfection of human 293 cells. RESULTS: The recombinant DMP1 was purified and characterized. CONCLUSION: The results suggested its future use in dental tissue regeneration and tissue engineering.
