The replenishment of specialized cells depends on the activity of stem cells. Recent advances in stem cell research have shown that the germline stem cells (GSCs) in Drosophila melanogaster can increase their mitotic activity in response to mating. Here, we show that this ability to respond to mating is eliminated if the males are mutant for the ABC transporter, White, the genetic background for a plethora of fly lines. Furthermore, we were not able to reproduce previous findings that female flies increase their GSC numbers and mitotic activity upon mating. Our findings underline the importance of careful experimental design and control specimen.
