Cultures of embryonic Drosophila melanogaster cells were examined by electron microscopy and events in myogenesis were recorded. Thick and thin myofilaments, T-tubules and sarcoplasmic reticulum all appeared at about the same time, 10.5 hr. This was about 5 hr after the final division of myoblasts and about the time that muscle cells were elongating, aligning and fusing. Sarcoplasm typical of insect muscle was detected by 18.5 hr, as were myotendonal and tendocuticular junctions. Two populations of myocytes were detected, the cytoplasm of one more electron-dense than the other. The only previous report of myofibrilogenesis in invertebrate embryos had described novel mechanisms. In Drosophila embryonic material, however, the sequence of myofibrilogenesis resembled that in postembryonic insect or vertebrate material.
