Preparation and physical properties of a novel biocompatible porcine corneal acellularized matrix

In Vitro Cell Dev Biol Anim. 2010 Jul;46(7):600-5. doi: 10.1007/s11626-010-9328-9. Epub 2010 Jun 9.

Abstract

This study was to investigate the stability, physico-mechanical property and biocompatibility of porcine corneal acellularized matrix (PCAM) that was prepared using human sera treatment to decellularize corneas. The stability (the rate of biodegradation) and physico-mechanical property (water uptake, density, and porosity) of PCAM were not compromised, compared with porcine fresh cornea matrix (PFCM, p > 0.05). The contact and extract cytotoxicity tests with human corneal epithelial cells and human keratocytes showed that PCAM has a good biocompatibility ex vivo and no cytotoxic effect. These results present the ability to create safety scaffolds that function as cornea grafts and provide a novel experimental approach for the study of cornea tissue engineering using acellular porcine cornea.
