The Craniofacial Developmental Molecular Biology Program will consist of investigators from the University of Southern California, Schools of Dentistry and Medicine who participate in a multi-disciplinary research team focused on investigations of craniofacial genetics and developmental biology. The faculty collaboration includes investigators from the USC Institute of Genetic Medicine, the USC Comprehensive Cancer Center and the USC Center for Craniofacial Molecular Biology. The overall Program theme will use molecular biology approaches to investigate fundamental mechanisms required for normal development of the craniofacial complex. These findings will be applicable to further the understanding of normal developmental regulation and the molecular etiology of craniofacial birth defects. The Craniofacial Developmental Molecular Biology Program will consist of five Research Projects and one Core Resource. Project 1 (Dr. Yang Chai), "Characterization of Genes Involved in the Specification of Tooth and Meckel's Cartilage Morphogenesis," will characterize the Smad- related intracellular signaling pathway that is activated during mandibular morphogenesis. Project 2 (Dr. Larry Kedes) "Co-Activators and Repressors of Muscle Transcription," will investigate the activity of Twist, p300/CBP and PCAF during the differentiation of muscle cells. Project 3 (Dr. Yi-Hsin Liu) "Genes Involved in Skull Suture Morphogenesis," will examine patters of gene expression unique to the cranial sutures that may be correlated with abnormal suture development resulting in craniosynostosis. Project 4 (Dr. Robert Maxon) "Function of MSX2 and Twist in Calvarial Morphogenesis," will examine the regulation and activation of interacting transcription factors Twist and Msx2 during bone cell commitment and differentiation. Project 5 (Dr. Charles Shuler) " Mechanisms of Epithelial-Mesenchymal Transformation during Palatogenesis," will investigate the molecular mechanism underlying the epithelial-mesenchymal transdifferentiation of the medial edge epithelium during palatal fusion. The activities of the Program will be supported by an Administrative Core that will provide support for purchasing, manuscript preparation, scheduling for seminars and collaborative research planning and financial management. The Program will benefit from the availability of several other established cores at the University of Southern California available to support the research activities of all the Projects. This program will continue a long-term series of collaborations that have provided an excellent scientific environment to advanced the understanding of the molecular mechanisms underling craniofacial development.

颅面发育分子生物学项目将由来自南加州大学牙科学院和医学院的研究人员组成，他们参与了一个多学科的研究团队，专注于颅面遗传学和发育生物学的研究。教师合作包括来自南加州大学遗传医学研究所、南加州大学综合癌症中心和南加州大学颅面分子生物学中心的研究人员。整个计划主题将使用分子生物学方法来研究颅面复合体正常发育所需的基本机制。这些发现将适用于进一步了解正常发育调节和颅面出生缺陷的分子病因。颅面发育分子生物学计划将由五个研究项目和一个核心资源组成。项目1（杨柴博士），“参与牙齿和梅克尔软骨形态发生的基因描述”，将描述在下颌形态发生过程中激活的Smad相关的细胞内信号通路。项目2 （Larry Kedes博士）“肌肉转录的共同激活因子和抑制因子”将研究Twist、p300/CBP和PCAF在肌肉细胞分化过程中的活性。项目三（刘义新博士）“与颅骨缝合形态发生相关的基因”，将研究颅骨缝合线特有的基因表达模式，这些基因表达模式可能与导致颅缝闭合的异常缝合线发育相关。项目4 （Dr. Robert Maxon）“MSX2和Twist在颅骨形态发生中的功能”将研究在骨细胞承诺和分化过程中相互作用的转录因子Twist和MSX2的调节和激活。项目5 （Charles Shuler博士）“腭发育过程中上皮-间质转化机制”，将研究腭融合过程中内边缘上皮-间质转分化的分子机制。该计划的活动将由一个行政核心提供支持，该核心将为采购、稿件准备、研讨会安排、合作研究计划和财务管理提供支持。该计划将受益于南加州大学其他几个已建立的核心，以支持所有项目的研究活动。该项目将继续开展一系列长期合作，为深入了解颅面发育的分子机制提供良好的科学环境。
