choroid plexus

They focused on a small region called the choroid plexus, which is known as a major conduit of immune cells into the brain.

Laminin is also a component of the meninges2 and is present in a CNS structure called the choroid plexus, which is where immune cells and cells from solid tumours often enter the CNS3.

Most clusters include cells from all samples, except for a cluster expressing blood genes and a cluster expressing choroid plexus epithelial cells that are mostly from animal WT5E.

Many of them also contain areas which look like choroid plexuses.

After a month, the fragments had organized themselves into primitive structures that could be recognized as developing brain regions such as retina, choroid plexus and cerebral cortex, the researchers explained in a telephone briefing.
