During cell division, a ring forms around the cell equator, which contracts to divide the cell into two daughter cells. Together with researchers from Heidelberg, Dresden, Tübingen and Harvard, Professor Jan Kierfeld and ...

During the final stage of cell division, a short-lived contractile ring constricts the cellular membrane and eventually separates the dividing cell in two. Although this "molecular muscle's" composition, mainly actin and ...

Researchers of the FOM Institute AMOLF and from Marseille and Paris have demonstrated that cells require a protein called septin to build a ring of actin filaments. This ring of proteins is crucial to drive cell division. ...

Proper cell division is a basic process critical to cell survival. A ring composed of actin filaments and myosin motor proteins pinches the cell apart, producing two daughter cells with equal amounts of cellular components.

Rod-shaped bacterial cells normally divide by constriction midway along their long axis. LMU physicists have developed a theoretical model to explain how Myxococcus xanthus localizes the plane of division to mid-cell.

Cell division is a fundamental biological process which ensures that, following the replication of the mother cell's genome, the two sets of chromosomes are equally distributed between two daughter cells. Chromosomes are ...
