Evaluation of a new type of wound dressing made from recombinant spider silk protein using rat models

This study investigates the feasibility of recombinant spider silk protein as a wound-dressing material for coverage of deep second-degree burn wounds using an animal model. Sixty Sprague–Dawley (SD) rats were randomly divided into four groups (15 rats in each group). Two types of recombinant spider silk proteins, pNSR-16 and pNSR-32, as well as collagen (as a control) were applied on the wound; the fourth group was left untreated as a negative...
