Muscle cell cultures from Drosophila melanogaster were obtained by plating dissociated gastrula stage embryo cells on protamine-treated culture dishes. They myogenic cells in these cultures fuse to form multinucleated pulsating cells by 15 hr after plating. An analysis of protein synthesis during myogenesis in these cultures, as measured by the(More)
The tissue and developmental specificities of the three Drosophila isoactins, originally identified in primary myogenic cultures and in the permanent Schneider L-2 cell line, have been investigated. Of these three isoactins (I, II, and III), actins I and II are stable and actin III is unstable. Two-dimensional polyacrylamide gel electrophoretic analyses of(More)
