Reporter:	lacZ
Antibody:	anti-B-galactosidase

Structure	Level	Pattern	Image	Note
TS19: cerebellum primordium	Present	Regionally restricted	4A center , 4A right	Expression was detected at the surface of the cerebellar anlage. There was no overlapping of expression with Wls.

Structure	Level	Pattern	Image	Note
TS19: cerebellum primordium	Present	Regionally restricted	4B right , 4B center	Expression was detected at the surface of the cerebellar anlage. A minimal number of cells showed coexpression with Lmx1a.

Structure	Level	Pattern	Image	Note
TS21: cerebellum	Strong	Regionally restricted	5B , 5C	Expression was strong in the emerging external granule cell layer.
TS21: rhombic lip	Present	Regionally restricted	5B , 5C	Columns of expression were detected in the rhombic lip. There was some overlap with Wls expression.

Structure	Level	Pattern	Image	Note
TS23: cerebellum external granule cell layer	Present		5F , 5E
TS23: rhombic lip	Present		5F , 5E	Expression was detected in the exterior face of the rhombic lip, continuous with the forming external granule cell layer. Expression was largely non-overlapping with Wls with only a few co-expressing cells.

Structure	Level	Pattern	Image	Note
TS26: cerebellum external granule cell layer	Present		5I , 5H	There was no co-expression with Wls.

Structure	Level	Pattern	Image	Note
TS23: rhombic lip	Present	Regionally restricted	6_center , 6_right	LacZ reporter was detected in the rhombic lip. Co-expression with Wls was seen in the interior face of the rhombic lip in many more cells in the mutant compared to the wild type.
