Characterizing expression pattern of Six2Cre during mouse craniofacial development

Abstract

Craniofacial development is a complex process involving diverse cell populations. Various transgenic Cre lines have been developed to facilitate studying gene function in specific tissues. In this study, we have characterized the expression pattern of Six2Cre mice at multiple stages during craniofacial development. Our data revealed that Six2Cre lineage cells are predominantly present in frontal bone, mandible, and secondary palate. Using immunostaining method, we found that Six2Cre triggered reporter is co-expressed with Runx2. In summary, our data showed Six2Cre can be used to study gene function during palate development and osteogenesis in mouse models.
