The primary MTOC in a cell is called the centrosome, and it is usually located adjacent to the nucleus. Microtubules tend to grow out from the centrosome to the plasma membrane.

Microtubules: the cell’s towropes. ... To do this, the microtubule must connect, via a motor protein, to an actin cable anchored in the cell membrane of the emerging daughter cell.

Along with actin, microtubules are an essential component of the cytoskeleton, and they serve to determine a cell ’ s shape as well as its movements. Microtubules are vital to processes such as ...

During cell division, new microtubules form on the sides of existing ones to create a branched network. The sites where new microtubules will grow are marked by globules of condensed TPX2.

BERKELEY, CA – Microtubules are active protein polymers critical to the structure and function of cells and the process of cell division. In a living cell their growing ends constantly elongate ...

Using the zebrafish, the authors showed the progressive establishment and maintenance of planar cell polarity in the zebrafish floorplate. To do this, they detected the posterior localization of the ...

Molecular motor grows cell's microtubules Date: October 26, 2015 Source: Penn State Summary: Motor proteins that pause at the ends of microtubules and produce pushing forces can also stimulate ...

The gossamer of membrane tucks away inside the cell in neat, well-defined pleats. “When you store pleats on the helical angle in this way, you can store an infinite amount of material,” Flaum ...

Migrating cells use stiffened microtubules to push through tissue barriers, seeking out weak points in tissue, according to a Northwestern Medicine study published in Cell Reports.
