BMC Biotechnology recently published our paper that is the first report of transgenic L. sericata that express and secrete a human growth factor. Sterile L. sericata maggots are approved for debridement of wounds. The maggots clean the wound and inhibit 
bacterial growth but randomised trials have not shown that this therapy shortens wound healing times. The long term goal of our research is to make GM strains that express a variety of antimicrobial peptides and growth factors that enhance wound healing. The image is of GM maggots that express PDGF-BB
