The Drosophila male germline provides a strong model system to understand numerous developmental and cell-biological processes, owing to a well-defined anatomy and cell type markers in combination with various genetic tools available for the Drosophila system. A major weakness of this system has been the difficulty of approaches for obtaining material for biochemical assays, proteomics, and genomic or transcriptomic profiling due to small-size and complex tissues. However, the recent development of techniques has started allowing us the usage of a low amount of material for these analyses and now we can strategize many new experiments. The method for enrichment or isolation of rare populations of cells is still challenging and should meaningfully influence the reliability of the results. Here, we provide our semi-optimized protocol of enrichment of undifferentiated germ cells and somatic cells from non-tumorous Drosophila testis, which we have successfully improved after multiple trials.
