Filopodial-Tension Model of Convergent-Extension of Tissues
Fig 4
Competition between filopodial tension and surface tension in the 2D filopodial tension model.
(A) The elongation time (τ) till the tissue’s inverse aspect ratio decreases to 0.5 as a function of the filopodial tension (λforce) of the cells for different surface tensions (γ). (B) Insert: Degree of tissue deformation (κ) as a function of λforce. An increase in the surface tension of the tissue reduces the final degree of CE (larger κ) shifting the κ vs. λforce curve to the right. The opposite effect happens when the surface tension is decreased. Main: The κ vs. λforce curves collapse when we rescale with the tension force by the surface tension plotting κ vs. λforce/γ.
