Centrioles are cylindrical structures involved in the generation of microtubules - fibers inside of cells that form a network to provide structure and shape to cells and to mediate transport processes ...

Centrosomes are not essential for cell division in most animal cells, although they contribute to the efficiency of mitotic spindle assembly. Centrosome loss is tolerated surprisingly well in fly ...

Tubulin superfamily members are essential for maintaining the microtubule cytoskeleton. α- and β-tubulin form the basic subunit of the microtubule polymer and assembly of microtubules is nucleated at ...

Centrioles are surrounded by pericentriolar material (PCM), which is proposed to promote new centriole assembly by concentrating γ-tubulin. Here, we quantitatively monitor new centriole assembly in ...

Cells contain various specialized structures - such as the nucleus, mitochondria or peroxisomes - known as "organelles''. Tracing their genesis and determining their structure is fundamental to ...

Centrioles are cylindrical structures involved in the generation of microtubules—fibers inside of cells that form a network to provide structure and shape to cells and to mediate transport processes.

Most knowledge on centrioles has been built by studying dividing animal cells in a narrow group of species, like flies or humans. “Recent technological advances in several fronts allow us to study ...

Human sperm cells are well-studied, so scientists were completely surprised to find a previously unknown structure in the little swimmers. And perhaps more surprising, this newfound structure may ...

Advanced microscopes have helped scientists discover a new component of sperm. Scientists now believe sperm contain two centriole structures, which are vital for fertilizing an egg. Researchers ...
