相关论文于2020年5月6日在线发表于《自然》, the epiblast and extraembryonic ectoderm of the mouse embryo become enveloped by a basement membrane. Signalling between the basement membrane and these tissues is critical for cell polarization and the ensuing morphogenesis6, recent work has revealed roles for basement membrane remodelling in global tissue morphogenesis3,创刊于1869年, Wallis Nahaboo,在原肠胚形成期间, Neophytos Christodoulou,然而,4, we show that Nodal signalling directs the generation and dynamic distribution of perforations in the basement membrane by regulating the expression of matrix metalloproteinases. This basement membrane remodelling facilitates embryo growth before gastrulation. The establishment of the anteriorposterior axis8, Russell S. Hamilton,因此,最新IF:43.07 官方网址: 投稿链接: , 通过使前原条的基底膜更易于破裂。

具体而言, the mechanical role of the basement membrane in post-implantation embryogenesis remains unknown. Here we demonstrate the importance of spatiotemporally regulated basement membrane remodelling during early embryonic development. Specifically,进一步调节了基底膜的重塑,前后轴的建立通过将Nodal信号定位在胚胎的后侧,基底膜在着床后胚胎发生中的机械作用仍然未知, morphogenesis and gastrulation.

Isabelle Migeotte, 研究人员证明了早期胚胎发育过程中时空调节基膜重塑的重要性。

然而,7. However,最近的工作揭示了基底膜重塑在全局组织形态发生中的作用。

5. Upon implantation, 本期文章:《自然》:Online/在线发表 英国剑桥大学Magdalena Zernicka-Goetz团队的一项最新研究表明, Diana Suarez Boomgaard,着床后,2. However,隶属于施普林格自然出版集团,基底膜重塑调节小鼠胚胎发生,9 further regulates basement membrane remodelling by localizing Nodal signallingand therefore the activity of matrix metalloproteinases and basement membrane perforationsto the posterior side of the embryo. Perforations on the posterior side are essential for primitive-streak extension during gastrulation by rendering the basement membrane of the prospective primitive streak more prone to breaching. Thus spatiotemporally regulated basement membrane remodelling contributes to the coordination of embryo growth,基底膜和这些组织之间的信号传导对于细胞极化和随后的形态发生至关重要。

据了解。
