Abstract

The thymus is a primary lymphoid organ composed of a three-dimensional (3D) epithelial network that provides a specialized microenvironment for the phenotypical and functional maturation of lymphoid progenitors. The specification of the pharyngeal endoderm to thymus fate occurs during the early stages of thymic organogenesis, independent of the expression of the transcription factor Foxn1. However, Foxn1 governs the later organogenesis of thymus together with the colonizing lymphoid cells. In the present chapter, we will review recent evidence on the topic covered in our original chapter (Muñoz and Zapata 2019). It described the early development of thymus and its resemblance to the development of endoderm-derived epithelial organs based on tubulogenesis and branching morphogenesis as well as the molecules known to be involved in these processes.

胸腺个体发生与发育。
胸腺是一个由三维(3D)上皮网络组成的初级淋巴器官,为淋巴祖细胞的表型和功能成熟提供了一个特殊的微环境。咽部内胚层对胸腺命运的指定发生在胸腺器官发生的早期阶段,独立于转录因子Foxn1的表达。然而,Foxn1与定植的淋巴样细胞一起支配着后来的胸腺器官发生。在本章中,我们将回顾有关原始章节(Muñoz和Zapata 2019)所涵盖主题的最新证据。它描述了胸腺的早期发育及其基于小管形成和分支形态发生的内胚层上皮器官发育的相似性,以及已知参与这些过程的分子。
