Reinforced microtubules
Heart contractions cause periodic wavy buckling of microtubles. M uch of the mechanical strength of micro-tubules comes from the cytoskeleton surrounding them, report Brangwynne et al. on page 733. When compressive forces push on a microtubule in a cell, such as when a growing polymer butts up against the cell edge, the fi ber bends in multiple short wavelength curves like a snake. By contrast,...
متن کاملNanobiomechanical Properties of Microtubules
Microtubules, the active filaments with tubular shapes, play important roles in a wide range of cellular functions, including structural supports, mitosis, cytokinesis, and vesicular transport, which are essential for the growth and division of eukaryotic cells. Finding properties of microtubules is one of the main concerns of scientists. This work helps to obtain mechanical properties of m...
متن کاملMicrotubules born on microtubules
Wnt ؉ BMP ؍ stem cell tem cell fate is determined by growth factors. But on page 309, Kléber et al. show that the right combination of growth factors can also keep cells from committing to a differentiated fate. Neural crest stem cells (NCSCs), they find, are maintained by the dual punch of Wnt and BMP. NCSCs have the potential to become many different cell types. For example, Wnt exposure of...

متن کاملDynamic Simulation and Mechanical Properties of Microtubules
This work is conducted to obtain mechanical properties of microtubule. For this aim, interaction energy in alpha-beta, beta-alpha, alpha-alpha, and beta-beta dimers was calculated using the molecular dynamic simulation. Force-distance diagrams for these dimers were obtained using the relation between potential energy and force. Afterwards, instead of each tubulin, one sphere with 55 KDa weight ...
