Abstract:

BACKGROUND: During the development of teeth, several signaling pathways, such as bone morphogenetic protein (BMP), fibroblast growth factor (FGF), Wnt, and sonic hedgehog (Shh) signaling pathways, transmit message between epithelium and mesenchyme. These mediators are required for cell division, differentiation, migration, survival and apoptosis.
OBJECTIVE: To review how the BMP, FGF, Wnt, and Shh signaling pathways regulate tooth development in order to provide reference for the study on stem cell differentiation into odontogenic cells. 
METHODS: Articles were retrieved from CNKI and PubMed database (from 2004 to 2017) with the key words of “bone morphogenetic protein, fibroblast growth factor pathway, Wnt protein, sonic hedgehog, tooth development, tooth organogenesis”. Studies related to molecular mechanisms of BMP, FGF, Wnt, Shh signaling pathway in tooth development and the recent articles with detailed, rigorous content as well as unambiguous viewpoint were included.
RESULTS AND CONCLUSION: The BMP, FGF, Wnt, and Shh signaling pathways are the pivotal molecular cascades throughout the whole stage of tooth development, regulating initiation, morphogenesis and cytodifferentiation of dental germ. Moreover, the four signaling pathways are closely related, promoting and restricting each other, and form a complex network. The reverse control mechanism of antagonistic factor is an important part of the network, which is critical to the terminal pattern and amount of the teeth.
