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 ...

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 ...

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 from a variety of sources, principally differentiating fibroblasts and smooth muscle cells from neonatal chicken and mammalian tissues and from organ cultures of chicken duodenum, were used as ...
