In a proof-of-concept study, NC State University researchers show that genetically engineered green bottle fly (Lucilia sericata) larvae can produce and secrete a human growth factor - a molecule that helps promote cell growth and wound healing. Sterile, lab-raised green bottle fly larvae are used for maggot debridement therapy (MDT), in which maggots are applied to non-healing wounds, especially diabetic foot ulcers, to promote healing. Maggots clean the wound, remove dead tissue and secrete anti-microbial factors. The treatment is cost-effective and approved by the Food and Drug Administration. However, there is no evidence from randomized clinical trials that MDT shortens wound healing times. http://medicalxpress.com/news/2016-03-maggots-human-wound.html
