Summary The differentiation of muscles in primary cultures of cells fromDrosophila melanogaster embryos was investigated. In early cultures, and in the absence of exogenous ecdysone, two main classes of muscle were found. Comparison, by light and electron microscopy, of one of these classes (the “myotube” class) with muscles from third instar larvae shows that this class corresponds to the muscles of the body wall of the larva. When α- or β-ecdysone is added to the cultures, these undergo a number of metamorphic changes. Most of the larval muscles disappear, and two new types of muscle form. Ultrastructural and light microscopic examination of these two types indicates that they correspond to the two classes of skeletal muscle (fibrillar and tubular) found in adult flies.
