TS21: cerebellum ventricular layer	Present		7A WT left , 7A WT right BLBP	Expressed in radial glia progenitors, which were tightly arranged in a few cell layers along the ventricular lining.

Structure	Level	Pattern	Image	Note
TS21: cerebellum ventricular layer	Present		7A CKO right BLBP , 7A CKO left	Expressed in radial glia progenitors, which were considerably dispersed and less tightly arranged as compared to the wild-type. Some were displaced basally and some were maintained in the ventricular surface.

TS23: cerebellum ventricular layer	Present		7B WT middle BLBP , 7B WT right , 7B WT left , 7B WT middle Overlay	Expressed in radial glia progenitors. Dorsally directed processes were seen.

Structure	Level	Pattern	Image	Note
TS23: cerebellum ventricular layer	Present		7B CKO left , 7B CKO middle BLBP , 7B CKO middle Overlay , 7B CKO right	Reduced number of positive radial glia progenitors and radial glia processes were randomly distributed. Cell bodies were abnormally elongated in a horizontal rather than vertical plane along the ventricular surface and also situated aberrantly in basal locations.
