Cell division: Biochemically controlled mechanics
Technical advances are providing new insights into the mechanical properties of cells. Now, by combining genetic and biochemical studies with high-resolution mechanical measurements from atomic force microscopy, the biochemical bases of mechanical processes such as cytokinesis should be discernible.
متن کاملThe mechanics of microtubule networks in cell division
The primary goal of a dividing somatic cell is to accurately and equally segregate its genome into two new daughter cells. In eukaryotes, this process is performed by a self-organized structure called the mitotic spindle. It has long been appreciated that mechanical forces must be applied to chromosomes. At the same time, the network of microtubules in the spindle must be able to apply and sust...
متن کاملMechanics of Constriction during Cell Division: A Variational Approach
During symmetric division cells undergo large constriction deformations at a stable midcell site. Using a variational approach, we investigate the mechanical route for symmetric constriction by computing the bending energy of deformed vesicles with rotational symmetry. Forces required for constriction are explicitly computed at constant area and constant volume, and their values are found to be...
متن کاملThe structural mechanics of cell division in Trypanosoma brucei.
Undoubtedly, there are fundamental processes driving the structural mechanics of cell division in eukaryotic organisms that have been conserved throughout evolution and are being revealed by studies on organisms such as yeast and mammalian cells. Precision of structural mechanics of cytokinesis is however probably no better illustrated than in the protozoa. A dramatic example of this is the pro...
