A The membrane is connected to the membrane skeleton by rows of transmembrane picket-proteins, according to the picket-fence model32. The protein rows subdivide the membrane into compartments and serve as barriers to the membrane flow. The membrane within each compartment bulges outwards because of a contraction of the membrane skeleton. B A schematic representation of the cross-sections of the dome-like shapes of the membrane compartments and the notations. \(P\) is the intracellular pressure and \(a\) is the membrane compartment radius in the base plane. C A schematic representation of an element of the compartment boundary and the notations: \(\zeta\) is the cross-sectional radius of a trans-membrane picket-protein, 2 h is the center-to-center distance between two adjacent picket-proteins and \(U\) is the velocity of the 2D membrane flow.
