Neural tube formation The central nervous system is derived from the neural tube, which appears during the fourth week after fertilization. At this early stage the embryo takes the form of a trilaminar germ disc, lying in the floor of the amniotic sac (Fig. 2.1). The germ disc is composed...
neural tube_胚胎学行业词汇 神经管 neural tube词源英文解释 The first known use of neural tube was in 1888 neural tube医学词典英英释义 neural tubenoun the hollow longitudinal dorsal tube that is formed by infolding and subsequent fusion of the opposite ectodermal folds in the vertebrate embryo and...
The future central nervous system is derived from an unspecified sheet of ectoderm, with fate being instructed by signals emanating, in the main, from a specialized region of the early embryo, the organizer. The organizer secretes signals that have the net effect of inhibiting the BMP pathway, ...
Neurons derive from the more apical daughter in asymmetric divisions in the zebrafish neural tube 来自 掌桥科研 喜欢 0 阅读量: 66 作者:P Alexandre,AM Reugels,D Barker,E Blanc,JDW Clarke 摘要: In the developing CNS, asymmetric cell division is critical for maintaining the balanced production of...
1c). The primary division is between neuronal and non-neuronal cell types, which are in turn split into ependymoglial cells (that is, neural-tube-derived glia) and other cells (that is, vascular cells, meningeal fibroblasts, blood cells and glial cells from the peripheral nervous system (...
This chapter discusses the dorsoventral subdivisions of the neural tube. The lateral wall of the neural tube is divided by the sulcus limitans into dorsal and ventral portions termed the alar and basal plates, respectively. The dorsal and ventral walls are referred to as the roof and floor plat...

Studies from our group and others have shown that in vitro somite myogenesis is regulated by neural tube and notochord factors including Wnt, Sonic hedgeho... A Pirskanen,JC Kiefer,SD Hauschka - 《Developmental Biology》 被引量: 142发表: 2000年 The influence of neural tube-derived factors on...
We use this system to recreate neural tube folding from human stem cells in a dish. Upon neural induction5,6, neural ectoderm folds into a millimetre-long neural tube covered with non-neural ectoderm. Folding occurs at 90% fidelity, and anatomically resembles the developing human neural tube. ...
In vivo, the neural tube forms from a planar neuroepithelial sheet that folds together to generate the lumen-containing tube. It is interesting that in vitro, as the ESCs divide and progress along the neural lineage, they generate a lumen at quite early stages corresponding to primitive ...
