Abstract

As the inner lining of the vessel wall, vascular endothelial cells are poised to act as a signal transduction interface between haemodynamic forces and the underlying vascular smooth-muscle cells. Detailed analyses of fluid mechanics in atherosclerosis-susceptible regions of the vasculature reveal a strong correlation between endothelial cell dysfunction and areas of low mean shear stress and oscillatory flow with flow recirculation. Conversely, steady shear stress stimulates cellular responses that are essential for endothelial cell function and are atheroprotective. The molecular basis of shear-induced mechanochemical signal transduction and the endothelium's ability to discriminate between flow profiles remains largely unclear. Given that fluid shear stress does not involve a traditional receptor/ligand interaction, identification of the molecule(s) responsible for sensing fluid flow and mechanical force discrimination has been difficult. This review will provide an overview of the haemodynamic forces experienced by the vascular endothelium and its role in localizing atherosclerotic lesions within specific regions of the vasculature. Also reviewed are several recent lines of evidence suggesting that both changes in membrane microviscosity linked to heterotrimeric G proteins, and the transmission of tension across the cell membrane to the cell–cell junction where known shear-sensitive proteins are localized, may serve as the primary force-sensing elements of the cell.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Stem cells sense active and passive forces from their external microenvironment and convert these physical stimuli into biochemical responses.

    “it is now increasingly appreciated that stem cells also experience active and passive forces from their external microenvironment and convert these physical stimuli into biochemical responses19.”

    From Organoids (2022) · cites this paper as [19]

    The section headed “Do changes in membrane fluidity modulate mechanochemical signal transduction?” describes cells converting mechanical stimuli into biochemical signals. The review discusses this process in endothelial cells, however; it does not establish the claim specifically for stem cells or distinguish active and passive forces in their microenvironment.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
