Figure 4: Surface of the roof of the fourth ventricle.

From: Identification of novel cellular clusters define a specialized area in the cerebellar periventricular zone

Figure 4

SEM image in A1 shows a panoramic view of the ventricle, with lobe I (I) anterior to the choroid plexus (a, anterior, p, posterior). Magnification of the area shows the cilia that characterize the ependymal cells and a thickening that corresponds to the VMC (white arrow); this structure includes cells with only two cilia (yellow arrowheads in B,D) and with multiple small cilia (red arrowheads in B,D). These cells also contain several spheroid structures (white arrowheads in B), and blood vessels were observed near this area (white arrowhead in E). The VMC is different from the uniform cellular organization found laterally that consists of multiple ciliated cells shown in (C) I: lobule I; ChP: choroid plexus; a: anterior; p: posterior.
