A new technique for development of rabbit ear Keloid model

Keloids and hypertrophic scars are an exaggeration of fibroplasia in dermal repair. keloids are found solely in humankind,and not in animals. thus far no practicable animal model of keloid has been made. recently a prototype rabbit ear keloid model has been produced by the authors by giving transforming growth factor beta 1 injection,and then skin punch excision on rabbit ear. in the present follow-up study consisting of eight refind techniques,best keloid was produced by the technique where transforming growth factor beta 1 injection was followed by ventral skin,ventral perichondrium,cartilage,and dorsal perichondrium punch excision,leaving behind only dorsal skin. copyright 2017 zoological society of pakistan.
