Coordinating cell polarization and morphogenesis through mechanical feedback. [PDF]
PLoS Computational Biology, 2021 Many cellular processes require cell polarization to be maintained as the cell changes shape, grows or moves. Without feedback mechanisms relaying information about cell shape to the polarity molecular machinery, the coordination between cell ...

Patterned mechanical feedback establishes a global myosin gradient [PDF]
Nature Communications, 2022 How does DNA encode shape? Here, via in toto light sheet microscopy and optogenetic control of cellular forces, the authors show that spatially patterned mechanical feedback loops establish the cytoskeletal patterns driving axis elongation tissue flow in

Mechanical feedback coordinates cell wall expansion and assembly in yeast mating morphogenesis. [PDF]
PLoS Computational Biology, 2018 The shaping of individual cells requires a tight coordination of cell mechanics and growth. However, it is unclear how information about the mechanical state of the wall is relayed to the molecular processes building it, thereby enabling the coordination

A Mechanical Feedback Classification of Linear Mechanical Control Systems
Applied Sciences, 2021 We give a classification of linear nondissipative mechanical control system under mechanical change of coordinates and feedback. First, we consider a controllable case that is somehow a mechanical counterpart of Brunovský classification, then we extend ...

Excitable dynamics driven by mechanical feedback in biological tissues [PDF]
Communications PhysicsPulsatory activity patterns, driven by mechanochemical feedback, are prevalent in many biological systems. However, the role of cellular mechanics and geometry in the propagation of pulsatory signals remains poorly understood.

Synthesis of nonlinear elastic couplings on the basis of modified kinematic graphs
Trudy Odesskogo Politehničeskogo Universiteta, 2017 In this work the analytical research of existing elastic couplings with linear mechanical feedback and synthesis was carried out taking into account passive elastic couplings with nonlinear mechanical feedback.

Modeling Interactions among Migration, Growth and Pressure in Tumor Dynamics
Mathematics, 2021 What are the biomechanical implications in the dynamics and evolution of a growing solid tumor? Although the analysis of some of the biochemical aspects related to the signaling pathways involved in the spread of tumors has advanced notably in recent ...
