Phase separation and critical size in molecular sorting
Elisa Floris, Andrea Piras, Francesco Saverio Pezzicoli +3
Molecular sorting is a fundamental process that allows eukaryotic cells to distill and concentrate specific chemical factors in appropriate cell membrane subregions, thus endowing…
Optimality in self-organized molecular sorting
Marco Zamparo, Donatella Valdembri, Guido Serini +4
We introduce a simple physical picture to explain the process of molecular sorting, whereby specific proteins are concentrated and distilled into submicrometric lipid vesicles in e…
On the Mean Residence Time in Stochastic Lattice-Gas Models
Marco Zamparo, Luca Dall'Asta, Andrea Gamba
A heuristic law widely used in fluid dynamics for steady flows states that the amount of a fluid in a control volume is the product of the fluid influx and the mean time that the p…
Universal features of cell polarization processes
A. Gamba, I. Kolokolov, V. Lebedev +1
Cell polarization plays a central role in the development of complex organisms. It has been recently shown that cell polarization may follow from the proximity to a phase separatio…
Spatial signal amplification in cell biology: a lattice-gas model for self-tuned phase ordering
Teresa Ferraro, Antonio de Candia, Andrea Gamba +1
Experiments show that the movement of eukaryotic cells is regulated by a process of phase separation of two competing enzymes on the cell membrane, that effectively amplifies shall…
3D simulations of early blood vessel formation
F. Cavalli, A. Gamba, G. Naldi +3
Blood vessel networks form by spontaneous aggregation of individual cells migrating toward vascularization sites (vasculogenesis). A successful theoretical model of two dimensional…
