Pattern Formation of Biomembrane Induced by Reaction-diffusion Dynamics of Curvature-inducing Proteins

Pattern formation by curvature-inducing proteins on spherical membranes

Spatial organisation is a hallmark of all living cells, and recreating it inmodel systems is a necessary step in the creation of synthetic cells. It is therefore of both fundamental and practical interest to better understand the basicmechanisms underlying spatial organisation in cells. In this work, we use a continuummodel ofmembrane and protein dynamics to study the behaviour of curvature-ind...

Pattern Formation by Reaction-diffusion

PROBLEM DEFINITION In biology, embryological development of the structure of an organism or limb is referred to as morphogenesis. As a result of morphogenesis, complex shapes and patterns can form starting from just a single cell. Two main mechanisms that contribute to the embryo’s development are cell movement and cell specialization based on cell position. These mechanisms are influenced by s...

Lateral diffusion induced by active proteins in a biomembrane.

We discuss the hydrodynamic collective effects due to active protein molecules that are immersed in lipid bilayer membranes and modeled as stochastic force dipoles. We specifically take into account the presence of the bulk solvent that surrounds the two-dimensional fluid membrane. Two membrane geometries are considered: the free membrane case and the confined membrane case. Using the generaliz...
