Notch signaling is a form of cellular communication that relies upon direct contact between cells. To properly induce Notch signaling in vitro, Notch ligands must be presented to cells in an immobilized state. This protocol describes methods for in vitro stimulation of Notch signaling in mouse osteoclast precursors.

Notch Signaling Pathway

2021
The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule. The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not until 1985...

Contact Angle

When a solid is dipped inside a liquid, the liquid surface becomes curved near the contact. For some solid–liquid interfaces, the liquid is pulled up along the solid, while for others, the liquid surface is convex or depressed near the solid surface. This phenomenon can be explained using the concept of cohesive and adhesive forces. The adhesive force is the molecular force between molecules of different materials, that is, between the molecules of the solid and the liquid. The cohesive force...

An Antibody Uptake Assay for Imaging Notch/DeltaD Signaling in Zebrafish Radial Glia Progenitors

2025
This video demonstrates an antibody uptake assay to image Notch/DeltaD signaling in zebrafish radial glia progenitors. It involves mounting agarose-embedded dechorionated zebrafish embryos, injecting a dye solution targeting DeltaD ligands on RGPs, and imaging under a fluorescence microscope for asymmetric cell division confirming Notch/DeltaD signaling activation.
FAQs
A smaller Notch Angle generally creates a sharper stress field near the root, increasing the component’s sensitivity to local loading effects. However, angle alone does not determine the response. Root radius, material behavior, and loading mode also influence how strongly stress concentrates, so meaningful interpretation requires considering these variables together rather than treating angle as an isolated factor.
Root radius changes the local sharpness of a notch independently of its included angle. Two specimens with the same Notch Angle can therefore respond differently if their root radii differ. Evaluating both dimensions helps engineers distinguish the influence of overall notch geometry from the influence of a highly localized root condition, improving comparisons of specimen behavior and defect sensitivity.
The same notch geometry can produce different results in different materials or under different loading modes. Material characteristics affect how the component responds to concentrated stress, while the loading mode changes the way stress reaches the notch root. Consequently, notch-angle comparisons are most useful when material and loading conditions are controlled or explicitly included in the analysis.
Specimen preparation requires selecting and maintaining the intended notch geometry, including the included angle and root condition. Consistent geometry allows results from fatigue, fracture, or tensile tests to be compared meaningfully. If the angle or root radius varies between specimens, observed differences may reflect geometry rather than material or loading behavior, weakening the reliability of the comparison.
Engineers vary or specify Notch Angle when they need to examine how a geometric discontinuity affects specimen behavior under a particular test type. Fatigue testing can support comparisons of repeated-loading response, fracture testing can examine defect sensitivity, and tensile testing can reveal how the geometry influences behavior under direct loading. The selected test depends on the engineering question.
These studies can indicate how sensitive a component or specimen is to a localized defect or geometric discontinuity. Results help engineers compare alternative notch configurations, recognize conditions associated with sharper stress fields, and guide safer design choices. Because the response also depends on root radius, material, and loading mode, test findings support predictions only when those factors remain relevant to the component.
