bioRxiv, 2021 Morphogens are signaling molecules that convey positional information and dictate cell fates during development. Although ectopic expression in model organisms suggests that morphogen gradients form through diffusion, little is known about how morphogen ...

A case for revisiting Nodal signaling in human pluripotent stem cells
Stem Cells, 2021 Nodal is a transforming growth factor‐β (TGF‐β) superfamily member that plays a number of critical roles in mammalian embryonic development. Nodal is essential for the support of the peri‐implantation epiblast in the mouse embryo and subsequently acts to

Symmetry-enforced Band Nodes in 230 Space Groups [PDF]
Phys. Rev. B 104, 045107 (2021), 2021 Crystallographic symmetries enforcing band touchings (BTs) in the Brillouin zone (BZ) have been utilized to classify and predict the topological semimetals. Though the early proposed topological semimetals contain isolated nodal points in the BZ, the proposed nodal line semimetals later could host various structures of several nodal lines/loops: nodal ...

Embryonic morphogen nodal is associated with progression and poor prognosis of hepatocellular carcinoma. [PDF]
PLoS ONE, 2014 BACKGROUND: Nodal, a TGF-β-related embryonic morphogen, is involved in multiple biologic processes. However, the expression of Nodal in hepatocellular carcinoma (HCC) and its correlation with tumor angiogenesis, epithelial-mesenchymal transition, and ...

Interlocking nodal chains and their examples in carbon networks [PDF]
Carbon 157, 563 (2020), 2020 Nodal chain is a typical topological phase in nodal line semimetals. Here, we propose a new topological phase -- interlocking nodal chains, in which two sets of nodal chains are interlocked each other. It includes one- (1D), two- (2D) and three-dimensional (3D) versions, which can be produced by a three-band model.

An essential role for maternal control of Nodal signaling
eLife, 2013 Growth factor signaling is essential for pattern formation, growth, differentiation, and maintenance of stem cell pluripotency. Nodal-related signaling factors are required for axis formation and germ layer specification from sea urchins to mammals ...
