Model systems for regeneration: Drosophila

ABSTRACT Drosophila melanogaster has historically been a workhorse model organism for studying developmental biology. In addition, Drosophila is an excellent model for studying how damaged tissues and organs can regenerate. Recently, new precision approaches that enable both highly targeted injury and genetic manipulation have accelerated progress in this field. Here, we highlight these techniques and review examples of recently discovered mechanisms that regulate regeneration in Drosophila larval and adult tissues. We also discuss how, by applying these powerful approaches, studies of Drosophila can continue to guide the future of regeneration research. Summary: In Drosophila, new precision approaches to inducing tissue damage have enabled targeted injury and genetic manipulation of regenerating tissue. Here, we discuss these techniques and the mechanisms that regulate regeneration in Drosophila larval and adult tissues.
