Structure	Level	Pattern	Image	Note
TS26: skeletal muscle	Strong	Non-Uniform	3C	There is high expression in the skeletal muscle, with intense staining observed in the intercostals and abdominal walls. Muscles in the extremities are also stained.
TS26: diaphragm	Very strong		3C
TS26: smooth muscle tissue	Absent		3C	There is slight, if any, expression in the smooth muscle.

Structure	Level	Pattern	Image	Note
TS26: skeleton	Present	Regionally restricted	3E	Expression is present in bone, especially in the epiphysis of tubular bone corresponding to cartilage. It is not present in the diaphysis, where the formation of bone has occured.

TS26: skeleton	Present	Regionally restricted	3F	Expression is present in bone, especially in the epiphysis of tubular bone corresponding to cartilage. It is not present in the diaphysis, where the formation of bone has occured.

TS26: bronchiole epithelium	Strong		3G

Structure	Level	Pattern	Image	Note
TS28: placenta	Present	Regionally restricted	3H	Expression is intense in the labyrinthine layer and moderate in the spongiotrophoblast layer.
TS28: decidua	Absent		3H

TS28: placenta	Present	Regionally restricted	3I	Expression is intense in the labyrinthine layer and moderate in the spongiotrophoblast layer.
TS28: decidua	Absent		3I

Structure	Level	Pattern	Image	Note
TS26: eye	Weak
TS26: metanephros	Weak
TS26: skin	Weak
TS26: brain	Absent			There is little, if any, expression in the brain.

Structure	Level	Pattern	Image	Note
TS26: embryo	Present	Regionally restricted		The expression patterns are similar to those seen in -/- animals, but the levels of expression are reduced.

Structure	Level	Pattern	Image	Note
TS22: embryo	Present	Regionally restricted		The expression patterns are similar to those seen at E18.5.
