Stretching short biopolymers by fields and forces.
We study the mechanical properties of semiflexible polymers when the contour length of the polymer is comparable to its persistence length. We compute the exact average end-to-end distance and shape of the polymer for different boundary conditions, and show that boundary effects can lead to significant deviations from the well-known long-polymer results. We also consider the case of stretching ...
متن کاملTheory of Biopolymer Stretching at High Forces.
We provide a unified theory for the high force entropic elasticity of biopolymers solely in terms of the persistence length, ξp , and the monomer spacing, a. When the force f>ℱ h ~ kBTξp /a2 the biopolymers behave as freely jointed chains (FJCs) while in the range ℱ l ~ kBT/ξp <f<ℱ h the worm-like chain (WLC) is a better model. We show that ξp can be estimated from the force extension curve (FE...
متن کاملCell-Fibronectin Interactions Propel Vertebrate Trunk Elongation via Tissue Mechanics
During embryonic development and tissue homeostasis, cells produce and remodel the extracellular matrix (ECM). The ECM maintains tissue integrity and can serve as a substrate for cell migration. Integrin α5 (Itgα5) and αV (ItgαV) are the α subunits of the integrins most responsible for both cell adhesion to the ECM protein fibronectin (FN) and FN matrix fibrillogenesis. We perform a systems-lev...
متن کاملLongitudinal Stretching for Maturation of Vascular Tissues Using Magnetic Forces
Cellular spheroids were studied to determine their use as "bioinks" in the biofabrication of tissue engineered constructs. Specifically, magnetic forces were used to mediate the cyclic longitudinal stretching of tissues composed of Janus magnetic cellular spheroids (JMCSs), as part of a post-processing method for enhancing the deposition and mechanical properties of an extracellular matrix (ECM...
متن کاملBounding cochordal cover number of graphs via vertex stretching
It is shown that when a special vertex stretching is applied to a graph, the cochordal cover number of the graph increases exactly by one, as it happens to its induced matching number and (Castelnuovo-Mumford) regularity. As a consequence, it is shown that the induced matching number and cochordal cover number of a special vertex stretching of a graph G are equal provided G is well-covered bipa...
