Mechanics of Anteroposterior Axis Formation in Vertebrates.

Summary of "Mechanics of Anteroposterior Axis Formation in Vertebrates."

The vertebrate anteroposterior axis forms through elongation of multiple tissues during embryogenesis. This process is based on tissue-autonomous mechanisms of force generation and intertissue mechanical coupling whose failure leads to severe developmental anomalies such as body truncation and spina bifida. Similar to other morphogenetic modules, anteroposterior body extension requires both the rearrangement of existing materials-such as cells and extracellular matrix-and the local addition of new materials, i.e., anisotropic growth, through cell proliferation, cell growth, and matrix deposition. Numerous signaling pathways coordinate body axis formation via regulation of cell behavior during tissue rearrangements and/or volumetric growth. From a physical perspective, morphogenesis depends on both cell-generated forces and tissue material properties. As the spatiotemporal variation of these mechanical parameters has recently been explored in the context of vertebrate body elongation, the study of this process is likely to shed light on the cross talk between signaling and mechanics during morphogenesis. Expected final online publication date for the , Volume 35 is October 7, 2019. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

Medical and Biotech [MESH] Definitions

The branch of physics which deals with the motions of material bodies, including kinematics, dynamics, and statics. When the laws of mechanics are applied to living structures, as to the locomotor system, it is referred to as BIOMECHANICS. (From Dorland, 28th ed)

The rotational force about an axis that is equal to the product of a force times the distance from the axis where the force is applied.

A Wnt protein and ligand for FRIZZLED RECEPTORS that may function as an inhibitor or activator of the WNT SIGNALING PATHWAY. For example, it activates signaling in the presence of Frizzled-4 but is inhibitory when coupled with ROR2 TYROSINE KINASE. It is required for axis formation during EMBRYOGENESIS and inhibits the proliferation, migration, and invasiveness of cancer cells.
