Filopodial-Tension Model of Convergent-Extension of Tissues
Fig 6
Contact-mediated pulling version of the model.
(A) Cells only pulls neighbors (here, 3) that share a common surface area (shown in red) and that lie inside a maximum angle with respect to the convergence plane (here the horizontal axis). (B) Dependence of τ and κ with λforce is qualitatively the same as before (Fig 4). (C) Dependence with nmax is reversed, with the speed of intercalation (τ-1) saturating after nmax = 3 and κ still decreasing. (D) The (κ τ,) x ϑmax curves are more symmetric, but the tissue still elongates more and faster at lower angles.
