제목 Characterization and in Vitro Biocompatibility of Liver Extracellular Matrix
초록 Liver regeneration requires growth factors, cells and a scaffold for optimal effectiveness. Previousstudies have noted the potential of decellularized liver (L-ECM) for tissue regeneration. Compared to epithelialorgans liver lobule lacks basement membrane and is mainly structured with a matrix consisting of fibronectinand collagen. L-ECM is also noted as a suitable substrate for immobilization of hepatocyte growth factor(HGF) which is beneficial in regenerating the hepatocytes. In this study several methods were investigated toproduce L-ECM viable for use as a biomaterial. L-ECM was prepared by decellularization of rabbit liverthrough freeze thaw method (FTM) or the use of Triton X-100 or sodium dodecyl sulfate (SDS).   Materialproperties of the L-PG were observed through Fourier transform infrared spectroscopy (FT-IR), transmittedelectron  microscopy  (TEM),   and  scanning  electron  microscopy  (SEM).   Remaining,   DNA/RNA,  sulfatedglycosaminoglycans (sGAG) and collagen was also quantified  to assess the effect  of  the  decellularizationprocess. In vitro cell biocompatibility was tested using rat bone marrow stem cells (rBMSC), pre-osteoblastcells (MC3T3-E1, endothelial cells (CPAE) and fibroblast cells (L929). The biocompatibility and the healingability of the  L-ECM was investigated by  applying in liver defect of rat models
