dc.description.abstract | Cell size and shape can be modified by hydrostatic pressure differences between both sides of its membrane. In order to analyze its behavior, two simplified models are evaluated. A model for vesicle expansion based on water uptake is applied to a spherical shaped vesicle. Results show a radius increase up to 20% in a time interval of the order of 10 minutes. On the other hand, we evaluate a model for membrane-cortex adhesion, which is related to membrane deformations due to local detachments. Simulations of the model are done considering both deterministic and stochastic dynamics. Results show that below a pressure difference threshold, only in stochastic simulations a membrane-cortex detachment occurs. Typical times for this process are of the order of 0.1 to 1000 s depending on the detachment condition imposed | ca |
