Structure	Level	Pattern	Image	Note
TS21: neural retina	Present	Regionally restricted	1A' , 1A	Expression was primarily detected in the ciliary margin of the neural retina. A few immunopositive cells were seen in the bottom of the ganglion cell layer. Expressing cells were not detected in the neuroblast layer.
TS21: lens epithelium	Present		1A

TS23: lens epithelium	Present		1B' , 1B
TS23: retina layer	Present	Regionally restricted	1B , 1B"	Broad expression was detected in the ganglion cell layer. Expression in the ciliary margin of the neural retina disappeared at E15.5. Expressing cells were not detected in the neuroblast layer.
