Microtubules 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 کاملCytoskeleton: Microtubules Born on the Run
The organization of microtubules into large arrays determines cell morphology and structure. Recent work in the fission yeast describes a novel mechanism for microtubule self-organization in the absence of centrosomes; this mechanism may function in a variety of cell types found in diverse organisms.
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 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 ...
