Abstract： BACKGROUND: Dlx gene family is highly expressed in the cranial neural crest cells, and regulates the cranial neural crest cel migration and differentiation. OBJECTIVE: To review the mechanism that the highly-expressed Dlx genes mediate the cranial neural crest cel migration and differentiation. METHODS: An online search of CNKI and Medline databases was performed for articles published before 2013 using keywords of “cranial neural crest cells, migration of cranial neural crest cells, Dlx, Dlx overexpression, Fgf, chodrogenesis, osteogenesis” in Chinese and English, respectively. Relevant articles were summarized from three aspects: the migration of cranial neural crest cells, Dlx over-expression’s impact on the migration of cranial neural crest cells, interaction between the environment and Dlx genes. A total of 63 articles were included. According to inclusion criteria, 43 articles were retained at last. RESULTS AND CONCLUSION: Dlx abnormal-expression wil lead to cel -cel adhesion. Dlx over-expression wil induce most of the cranial neural crest cells aggregate and migrate to a wrong place, and result in skeletal dysmorphology. Dlx over-expression wil also lead to ectopic chondrogenesis, and the interaction between cel factors can be the possible reason for this.
