项目摘要

ABSTRACT Congenital heart disease is the leading cause of death in the western world affecting approximately 1.3 million Americans. The heart initially forms in vertebrates as a bilaminar tube comprised of an inner endocardium and outer myocardial layer. At later stages of development a third layer is added to the heart from the epicardium which forms from a dynamic precursor structure, the proepicardial organ (PEO) which forms on the septum transversum, a structure adjacent to the heart. As the embryo matures, cells from the PEO migrate onto the heart surface ultimately giving rise to several essential cell types in the adult heart including cardiac fibroblasts and the smooth muscle cells of the vasculature. The aim of this proposal will leverage our series of unique technologies, reagents, and animal models to elucidate the molecular and cellular pathways required for the formation and function of the epicardium. In doing so, we will provide a platform for studying heart formation and hemostasis, and thus proved mechanistic insight into human congenital heart disease.

抽象的先天性心脏病是西方世界主要的死亡原因，影响约 1.3 百万美国人。脊椎动物的心脏最初形成为双层管，由内部心内膜和外心肌层。在开发的后期阶段，第三层被添加到心脏来自心外膜，心外膜由动态前体结构（心外膜器官）形成 (PEO) 形成于横隔上，横隔是与心脏相邻的结构。作为胚胎成熟后，PEO 中的细胞迁移到心脏表面，最终产生几种必需细胞成人心脏中的类型包括心脏成纤维细胞和脉管系统的平滑肌细胞。这该提案的目的是利用我们一系列独特的技术、试剂和动物模型阐明形成和功能所需的分子和细胞途径心外膜。这样做，我们将为研究心脏形成和止血提供一个平台，从而证明了对人类先天性心脏病的机制洞察。
