Drosophila melanogaster
Schneider 2 cells, usually abbreviated as S2 cells, are one of the most commonly used "Drosophila melanogaster" cell lines. S2 cells were derived from a primary culture of late stage (20–24 hours old) "Drosophila melanogaster" embryos by Dr. Imogene Schneider, likely from a macrophage-like lineage.
