Structure	Level	Pattern	Image	Note
TS19: ventricle cardiac muscle	Strong		2A	Abundant expression in ventricular myocardium compared with surrounding tissue.
TS19: myocardium layer	Strong	Ubiquitous	2A	Expression much higher and more evenly distributed between compact and trabecular zones at E11.5 than at E14.5.

Structure	Level	Pattern	Image	Note
TS22: trabecular myocardium	Strong		2D	Expression predominantly in trabecular zone.
TS22: compact myocardium	Weak		2D	Less expression in compact zone.
