Summary

Sarcomere assemblage in striated muscle of the early developing chick embryo was studied with the electron microscope. In myogenic chick somites, non-striated myofibrils are seen with the electron microscope, prior to striated ones. These crude myofibrils are traversed at regular periodic intervals by a tubular system which is associated with dense Z-line material shortly after its appearance. Longer sarcomeres as well as banding patterns similar to those found in mature striated muscle follow and possibly depend on prior Z-line formation.
