Traveling motility of actin lamellar fragments under spontaneous symmetry breaking García López, Claudia Magliocca, Martina Meunier, Nicolas Cell motility is connected to the spontaneous symmetry breaking of a circular shape. In [8], Blanch-Mercader and Casademunt performed a nonlinear analysis of the minimal model proposed by Callan and Jones [11] and numerically conjectured the existence of traveling solutions once that symmetry is broken. In this work, we prove analytically that conjecture by means of nonlinear bifurcation techniques. 2025-11-03T09:28:27Z 2025-11-03T09:28:27Z 2026-02-05 journal article García, C., Magliocca, M., & Meunier, N.
