Researchers create a biomimetic model to study wound healing in burn and laceration wounds. The team designed an in vitro model system made of fibroblasts embedded in a collagen hydrogel. Wounds were created in this microtissue using a microdissection knife to mimic laceration or a high-energy laser to simulate a burn. They discovered that fibroblasts clear away damaged tissue before depositing new material. This part of the healing process is slower in burn wounds.
