Interplay between Notch signaling and mechanical forces during developmental patterning processes.

The coordination between biochemical signals and cell mechanics has emerged in recent years as a crucial mechanism driving developmental patterning processes across a variety of developing and homeostatic systems. An important class of such developmental processes relies on local communication between neighboring cells through Notch signaling. Here, we review how the coordination between Notch-mediated differentiation and cell mechanics can give rise to unique cellular patterns. We discuss how global and local mechanical cues can affect, and be affected by, cellular differentiation and reorganization controlled by Notch signaling. We compare recent studies of such developmental processes, including the mammalian inner ear, Drosophila ommatidia, intestinal organoids, and zebrafish myocardium, to draw shared general concepts and their broader implications in biology.
