New study out on bioRxiv! We have studied how resources are shared between actin networks competing for a limited pool of components. biorxiv.org/content/10.110…

6. We then studied the same situation, in presence of turnover and we saw that the size of the structures has a weak dependence with the number of beads in the microwell.

7. We then looked at structures with various densities in competition for limiting ressources. For that, we prepared "weak" and "strong" beads. Without turnover, when the two beads are in competition in the same microwell , the weak bead never start to grow.

Guerin Alvéole 10. We then demonstrated that when there is turnover, weak structures (from beads or micropatterns) can grow when they are in competition with strong networks. Turnover enables the weakest to exist!

Guerin Alvéole To challenge the limits of the system, we studied conditions with many beads in the microwells. We then looked at the fraction of weak beads moving, as a function of competition strength (defined by the number of strong beads).
