The spindle apparatus of Coprinus micaceus begins to develop from the diglobular polar body outside the nucleus. During both meiotic divisions it operates inside the nuclear envelope and consists of ...

The orientation of cell division is tightly regulated to ensure proper tissue morphogenesis and to prevent cancerous growth. Cell division can be symmetric resulting in two equal daughter cells and ...

Eukaryotes assemble a microtubule-based spindle apparatus that separates chromosomes into daughter cells during cell division. Although studies of how spindle microtubules capture kinetochores of ...

Researchers from Ludwig-Maximilians-Universitaet (LMU) in Munich have identified a signaling pathway that restricts cleavage furrow formation to the mid-plane of the cell. Cell division is a ...

Cambridge, Mass. - April 26, 2012 - The mitotic spindle, an apparatus that segregates chromosomes during cell division, may be more complex than the standard textbook picture suggests, according to ...

The mitotic spindle, an apparatus that segregates chromosomes during cell division, may be more complex than the standard textbook picture suggests. The mitotic spindle, an apparatus that segregates ...

The findings shed light on the mechanisms behind "self-organization" - an essential characteristic of biological structures. Organisms are composed of a variety of structures including muscles, ...

Researchers have for the first time directly observed the “molecular motor”, called Xkid, that plays a critical role in facilitating the proper alignment of chromosomes during cell division. The study ...
