A) EGFP expression in the heart, somites and mid-brain of a MyocdKI/+;mTmGm/+ embryo. Notice that red fluorescence is diminished in regions in which EGFP is expressed. A mTmGm/+ single heterozygote embryo was included as a control (Scale bar, 1mm). B) EGFP expression in a 2 month old adult MyocdKI/+;mTmGm/+ mouse cardiovascular tissues such as the Atrium (A), Aorta (Ao), and in the left common carotid aortic branch (Ar), while EGFP is not observed in Adipose tissue (Ad) of (Scale bar, 2mm). C) EGFP expression in the foot pad (FP), skeletal muscle (SkM), tongue (To) and nostrils (No) of a 2 month old adult MyocdKI/+;mTmGm/+ mouse (Scale bar, 4mm).
