Tendon ruptures are a great burden in clinics. Finding a proper graft material as a substitute for tendon repair is one of the main challenges in orthopaedics, for which the requirement of a biological scaffold would be different for each clinical application. Among biological scaffolds, the use of decellularized tendon-derived matrix increasingly represents an interesting approach to treat ten...

When short segments are involved, primary re-anastomosis affords excellent results. Longer lesions, involving more than half...

Interactions between stem cells and extracellular matrix (ECM) are requisite for inducing lineage-specific differentiation and maintaining biological functions of mesenchymal stem cells by providing a composite set of chemical and structural signals. Here we investigated if cell-deposited ECM mimicked in vivo liver's stem cell microenvironment and facilitated hepatogenic maturation. Decellulari...

The tissues of a multicellular organism contain two main components, the cells themselves, onwhichmost biological research has traditionally focused, and the material that lies between the cells. This material is called the extracellular matrix, usually abbreviated to ‘ECM’. The ratio of tissue volume occupied by ECM to that occupied by cells varies from less than 1:10 (e.g. in muscles) to more...

The immune response due to Galα1,3-Galβ1-4GlcNAc-R(α-Gal) epitopes is an important factor in bioprosthetic heart valve failure. The aim of this study was to evaluate the immune reaction and anticalcification effect of α-galactosidase and decellularization for glutaraldehyde (GA)/genipin fixed bovine pericardium using α1,3-galactosyltransferase knockout(α-Gal KO) mouse(C57BL/6). Bovine pericardi...

Objective(s): Use of biological scaffolds and automating the cells directing process with materials such as growth factors and glycosaminoglycans (GAGs) in a certain path may have beneficial effects in tissue engineering and regenerative medicine in future. In this research, chondroitin sulfate sodium was used for impregnation of the scaffolds. It is a critical component in extracellular matrix...
