We report a direct examination of the expression of one collagen gene (DCg1) during Drosophila melanogaster metamorphosis, based on data from in situ hybridization. The transcripts of this gene, thought to encode a basement membrane type IV collagen, are mainly accumulated during ecdysis in wandering haemocytes. Our results demonstrate that haemocytes contribute to extracellular matrix deposition and seem to perform a fibroblastic function during Drosophila development.
