9. Self-assembled columns of stacked lipid bilayers mediated by metal ion recognition

Author

Waggoner, Tina A., Last, Julie A., Kotula, Paul G., and Sasaki, Darryl Y.

Subjects
Bilayer lipid membranes -- Research, Chemistry
Abstract

The identification of a synthetically produced higher ordered self-assembled structure made up of lipid bilayers with self-limiting dimensions mediated by chemical recognition at the membrane surface is reported. There is a columnar structure of stacked lipid bilayers uniform in width.

26. The physicochemical origins of coincident epitaxy in molecular overlayers: lattice modeling vs potential energy calculations

Abstract

Calculations of optimum overlayer-substrate configurations were performed using potential energy methods and a simple geometric lattice misfit modeling algorithm to determine the physicochemical origins of epitaxial stabilization of coincident molecular overlayers. The samples studied are beta-bis(ethylenedithio)tetrathiafulvalene triiodide, perylenetetracarboxylic diimide and perylenetetracarboxylic dianhydride overlayers on a graphite substrate. Results showed, at least for van der Waals overlayers, that overlayer orientations are influenced more by the phase relationship between the overlayer and the substrate than by specific molecule-substrate interactions.

Abstract

Abstract: Recent studies indicate that the biophysical properties of the cellular microenvironment strongly influence a variety of fundamental cell behaviors. The extracellular matrix’s (ECM) response to mechanical force, described mathematically as the elastic modulus, is believed to play a particularly critical role in regulatory and pathological cell behaviors. The basement membrane (BM) is a specialization of the ECM that serves as the immediate interface for many cell types (e.g. all epithelial cells) and through which cells are connected to the underlying stroma. Matrigel is a commercially available BM-like complex and serves as an easily accessible experimental simulant of native BMs. However, the local elastic modulus of Matrigel has not been defined under physiological conditions. Here we present the procedures and results of indentation tests performed on Matrigel with atomic force microscopy (AFM) in an aqueous, temperature controlled environment. The average modulus value was found to be approximately 450Pa. However, this result is considerably higher than macroscopic shear storage moduli reported in the scientific literature. The reason for this discrepancy is believed to result from differences in test methods and the tendency of Matrigel to soften at temperatures below 37°C. [Copyright &y& Elsevier]
