The proepicardium is a transient extracardiac embryonic tissue that gives rise to the epicardium and a number of coronary vascular cell lineages. This important extracardiac tissue develops through multiple steps of inductive events, from specification of multiple cell lineages to morphogenesis. This article will review our current understanding of inductive events involved in patterning of the proepicardium precursor field, specification of cell types within the proepicardium, and their extension and attachment to the heart.
心外膜原基是一种短暂的心外胚胎组织,可产生心外膜和许多冠状血管细胞谱系。这种重要的心外组织通过多个诱导事件步骤发育,从多个细胞谱系的特化到形态发生。本文将综述我们目前对参与心外膜原基前体区域模式形成、心外膜内细胞类型特化以及它们向心脏延伸和附着的诱导事件的理解。
