Numerous treatments have been used in the management of corneal chemical burns; however, no optimal treatment for corneal chemical burns currently exists. The present study investigated the effects of topical chondrocyte.derived extracellular matrix (CD-ECM) treatment on corneal wound healing, using an alkali burn mouse model. Topical treatment with CD-ECM was shown to reduce corneal opacity following an alkali burn. A histological examination observed the presence of regenerated epithelial cells and a small number of inflammatory cells in the corneas of CD-ECM-treated mice. The majority of the inflammatory cells present in the corneas of the phosphate.buffered saline (PBS)-treated mice were neutrophils that expressed matrix metalloproteinase (MMP)-9. The amount of neutrophils was significantly reduced in the corneas of the CD-ECM-treated mice. Furthermore, the expression levels of interleukin (IL)-8 were significantly reduced in the CD-ECM treatment group, but not in the mice that received the PBS treatment. The results of the present study indicate that CD-ECM treatment may accelerate wound healing in a model of alkali burn-induced corneal injury. The therapeutic mechanism may be associated with accelerated reepithelialization and reduced recruitment of MMP-9-Expressing neutrophils, through inhibiting the production of IL-8. Source
