"Pericyte actomyosin-mediated contraction at the cell-material interface can modulate the microvascular niche."
The conversion of the chemical energy of ATP into mechanical work by myosin involves coordinated changes in the actomyosin affinity and the orientation of myosin cross-bridges relative to the fiber axis

B, Yu LC (1993) Structural changes in the actomyosin cross-bridges associated with force generation.
The researchers demonstrated that any significant change in the dynamics of actomyosin assembly or par6α activity stops neuron migration in its tracks.
To determine if Bub2 has an effect on actomyosin ring contraction through its regulation of Tem1, we used live cell imaging of Myo1-GFP in a bub2Delta strain.
In healthy myocardium, cardiomyocytes attach to a collagen-based extracellular matrix that must be sufficiently flexible for actomyosin forces to pump the heart.
The perfect substrate, one that mimics the elasticity of normal heart tissue, provides an environment optimal for transmitting contractile work to the matrix and for promoting actomyosin striation and thus healthy and mature heart fibers.
Available information suggests that thrombin induces endothelial permeability by promoting actomyosin contractility through the Rho / ROCK signaling pathway.
