项目摘要

Abstract The cranial neural crest (CNC) cells, the migrating multipotent cells giving rise to different derivatives composing the majority of the craniofacial structures including bone, cartilage, neurons, glia, smooth muscle, melanocytes and adipocytes. Abnormal CNC development results in the most common congenital human birth defects like cleft lip/palate, craniosynostosis, and genetic syndromes, giving a large impact of the life of patients and their families. Therefore, the objective of our proposed study is to understand the molecular regulatory mechanism regulating CNC development. Key Hippo signaling roles have been broadly observed in development and diseases involving many different tissues and organs. However, Hippo's role in craniofacial development is still poorly understood. Wnt signaling is known to play a pivotal role in CNC development and cross talks with Hippo signaling in some context like in heart, whereas there is a knowledge gap of Hippo and Wnt interaction in craniofacial development. We have obtained promising preliminary data indicate that Hippo signaling interacts with Wnt signaling and plays a critical role in regulating CNC-derived craniofacial development. In this proposed study, we will dissect the important roles of Hippo-Yap pathway in CNC cells migration and differentiation, and how Hippo and Wnt pathways cross talk to regulate CNC derived craniofacial development. The goal of the proposed studies is to elucidate the molecular regulatory mechanisms underlying CNC development and help to develop novel therapeutic strategies and diagnostic tools for craniofacial defects.

摘要颅神经嵴（CNC）细胞，迁移的多能细胞，产生不同的细胞分化。包括骨，软骨，神经元、神经胶质、平滑肌、黑素细胞和脂肪细胞。异常CNC开发结果在最常见的先天性人类出生缺陷，如唇腭裂，颅缝早闭，遗传综合征，给患者及其家庭的生活带来很大的影响。因此我们拟议研究的目的是了解调节的分子调节机制 CNC开发Hippo的关键信号作用在发育和涉及许多不同组织和器官的疾病。然而，河马在颅面的作用对发展仍然知之甚少。已知Wnt信号在CNC中起关键作用在某些情况下，如在心脏中，Hippo信号的发展和交叉对话， Hippo和Wnt在颅面发育中相互作用的知识缺口。我们所获得有希望的初步数据表明，Hippo信号与Wnt信号相互作用，在调控CNC衍生的颅面发育中起关键作用。在这项研究中，我们将剖析Hippo-Yap通路在CNC细胞迁移和分化中的重要作用， Hippo和Wnt通路如何相互作用以调节CNC衍生的颅面发育。的本研究的目的是阐明CNC的分子调控机制开发和帮助开发新的治疗策略和诊断工具，颅面缺陷
