Key result
In embryonic chick skeletal muscle, α-, β-, and γ-actins are present and assembled into myofibrils, with β- and γ-actins disappearing as muscle development proceeds.

Does not yet alter clinical myopathy management; leaves open conservation of actin isoform transitions in mammalian myogenesis.
Shimizu et al. (1980) studied Skeletal muscle development. Developmental stage of skeletal muscle was evaluated on Proportions of actin types (α, β, γ) in soluble and myofibril fractions. In embryonic chick skeletal muscle, α-, β-, and γ-actins are present and assembled into myofibrils, with β- and γ-actins disappearing as muscle development proceeds.
