YAP reads contractility in the embryo 🐭 Asymmetric divisions give early blastomeres different contractility, which sorts them inside or outside. Contractility controls where Yap sits, and cells that lose it take on inner-cell-mass markers wherever they are.

Nuclear rotation before mitosis is thought to be caused by actin contractility, and the interaction of hydrodynamic forces. What else might we be missing from static images?

YAP is a general-purpose mechanosensor 📖 YAP/TAZ read stiffness, shape, stretch, shear and contractility and turn them into cell-specific gene programmes, with roles from embryos and stem cells to regeneration, fibrosis and cancer.

Cells frequently cross between compartments, yet persistent mispositioning remains rare.

Rather than preventing errors, these tissues continuously correct them. Differences in adhesion and contractility bias misplaced cells back toward their compartment, preserving tissue organization.

Interestingly, we find that calcium flashes drive the localized, pulsatile actomyosin contractility required for efficient tricellular zipping.

We discuss several other examples (in chick, mouse and Drosophila) where metabolic states regulate cellular behaviour, affecting mechanical transitions including increased contractility, tissue stiffening and epithelial-to-mesenchymal transition.

I’m not surprised this study was neutral and wouldn’t have been that surprised if CI-guided treatment led to harm. Lots to unpack.

In simple terms, the investigators have increased CI by increasing RA pressure (fluids), increasing contractility and reducing SVR (dobutamine).

Is this sensible?
