Reporter:	lacZ
Antibody:	anti-B-galactosidase

Structure	Level	Pattern	Image	Note
TS23: rhombic lip	Present	Regionally restricted	3_right , 3_center	Expression was in the cytoplasm and staining was punctate. Expression was predominately in the interior face of the rhombic lip, while cells of the exterior face of the rhombic lip were negative. The reporter co-localized with antibody staining.

TS19: rhombic lip	Present		4C center , 4C right	There was co-expression with Lmx1a.
TS19: hindbrain roof plate	Present	Regionally restricted	4C center , 4C right	Expression was detected in the choroid plexus. There was co-expression with Lmx1a.

Structure	Level	Pattern	Image	Note
TS23: rhombic lip	Strong	Regionally restricted	7_right , 7_left	Expression was robust in the interior face of the rhombic lip and light in the exterior face, and strong in the distal part of the rhombic lip. Co-expression was noted with light expressing Pax6-positive cells in the interior face.

Structure	Level	Pattern	Image	Note
TS23: rhombic lip	Present	Regionally restricted	9A right , 9A left	Expression was detected in the interior face of the rhombic lip. There was co-expression with Lmx1a, which had weak expression in this region.
