Chronic kidney disease has been recognized as a major public health problem worldwide and renal fibrosis is a common pathological process occurring in chronic renal failure. It is very promising to find the strategies to slow or even prevent the progression of fibrosis. This study focused on whether renal fibrosis decellularized scaffolds has the potential to be a model of cellular mechanisms of tissue fibrosis or donors for tissue engineering. In order to evaluate the feasibility of decellularized scaffolds derived from pathological kidneys, histology, proteomics and ELISA will be used to analysis the changes in the structure and main components of fibrotic tissue. The fibrosis model in this paper was induced by adenine-fed and the results showed that the structure of fibrotic scaffold was changed and some protein were up-regulated or down-regulated, but the cytokines associated with renal regeneration after injury were remained. In cell experiments, endothelial progenitor cells proliferated well, which proved that the fibrotic scaffolds have non-cytotoxic. All these conclusions indicate that the renal fibrosis decellularized scaffolds model has the ability to study fibrosis mechanism and the potential to be engineering donors as well as normal scaffolds.
