Expression of myl1 in post-somitogenic stages. A: Expression of myl1 was restricted to myogenic structures in the dorsal and ventral part of the trunk in the 24-hpf embryo. A2: Transverse section of 24-hpf embryo showing myl1 expression in the muscle domain. B: Expression of myl1 in 2-dpf embryo in whole mount showing myl1 specifically in the dorsal and ventral trunk. B2: Transverse section of 2-dpf embryo showing myl1 in the myogenic region of the trunk. C: Myl1 expression is expressed in the trunk musculature in 4-dpf juvenile fish, but at decreasing levels as compared to earlier stages of development. C2: Transverse section of 4-dpf fish showing myl1 in the myogenic region of the trunk. C3: Transverse section of 4-dpf fish showing myl1 expression in the craniofacial musculature.
