Initial description of the fusome occurred in the 19th century and since then the fusome has been extensively studied in Drosophila melanogaster male and female germline development. This structure has roles in maintaining germline cysts, coordinating the number of mitotic divisions prior to meiosis, and oocyte determination by serving as a structure for intercellular communication.thumb|A wild type D. melanogaster testis showing the fusome (spectrin, green), DNA (DAPI, blue), and germ cells (vasa, red). The fusome connects cells in a cyst and becomes branched as the cyst grows with cell divisions. Image by S. Brantley, used with permission by the author.
