摘要

In this study, mechanics of plasma membrane vesicles in cells have been theoretically investigated based on minimization of bending and in-plane shear strain energy of the membrane. The results are: ⅰ) The vesicles change their shapes dramatically as the opening radius increases. During the large deformation process, the sudden shape changes due to spontaneous curvature were observed accompanying with a step-like increase in strain energy, ⅱ) Effects of the in-plane shear modulus μ upon the equilibrium shape of the connected system were observed particularly in the vicinity of the neck part and the constricted part of the vesicles where curvature changes dramatically, ⅲ) The computed shape given by the present method is relatively in good agreement with the results observed on electron micrographs.
