Executing gene circuits by cell-free transcription−translation into cell-sized compartments, such as liposomes, is one of the major bottom-up approaches to building minimal cells. The dynamic synthesis and proper self-assembly of macromolecular structures inside liposomes, the cytoskeleton in particular, stands as a central limitation to the development of cell analogs genetically programmed. In this work, we express the Escherichia coli gene mreB inside vesicles with bilayers made of lipid-polyethylene glycol (PEG). We demonstrate that two-dimensional molecular crowding, emulated by the PEG molecules at the lipid bilayer, is enough to promote the polymerization of the protein MreB at the inner membrane into a sturdy cytoskeleton capable of transforming spherical liposomes into elongated shapes, such as rod-like compartments. We quantitatively describe this mechanism with respect to the size of liposomes, lipid composition of the membrane, crowding at the membrane, and strength of MreB synthesis. So far unexplored, molecular crowding at the surface of synthetic cells emerges as an additional development with potential broad applications. The symmetry breaking observed could be an important step toward compartment self-reproduction.

ABSTRACTAs an important method for preparing ordered mesoporous polymer and carbon, organic template directed self-assembly is facing challenges because of the weak non-covalent interactions between the organic templates and the building blocks. Herein we developed a novel synthetic procedure based on a reactive template-induced self-assembly to construct ordered mesoporous framework. The aldehyde end-group of reactive template can react with the building blocks (i.e., resol) to form a stable covalent bond during the self-assembly process. This leads to an enhanced interaction between resol and template and thus achieves the formation of ordered mesostructure.
