Microtubules in orbit
The faithful segregation of DNA during mitosis is critical to the life of a cell. A complex molecular machine called the mitotic spindle mediates this task. The spindle is made up of microtubule-binding proteins and microtubules on which the chromosomes are segregated. A complete understanding of the formation of the bipolar spindle and the mechanism of chromosome movement on the spindle remain...
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...
