Abstract

Recessive dystrophic epidermolysis bullosa (RDEB), an inherited disease featuring blistering wounds, causes constant inflammation that leads to the eventual development of an aggressive form of squamous cell carcinoma (RDEB SCC). The persistence of inflammatory chemokines such as MCP-1 and Il-8 in RDEB wounds may foster RDEB SCC carcinogenesis. We report the production of ternary composite nanofibers containing pullulan, chondroitin sulfate, and tannic acid as RDEB wound dressings. The swellable fibers are stable to hydration and absorb ∼500% their weight in water. The fibers remove ∼99% of MCP-1 from solution in <2 h. Scavenged media did not promote RDEB SCC migration.
