Preparation of Tissue-Specific Matrix from Decellularized Porcine Cartilage

For full decellularization of cartilage tissue when preparing tissue-specific matrices of dense tissues from decellularized porcine articular cartilage, treatment with surfactant should be followed by treatment with supercritical fluids. Ethanol introduced as a polarity modifier leads to more complete cartilage decellularization, which is associated with a reduction of destructive changes in the extracellular matrix. The preserved morphology and active proliferation of mesenchymal stromal cells of human adipose tissue in the presence of the tissue-specific matrix of porcine cartilage indicate that the matrix is promising for use as a cell carrier for tissue engineering of cartilage.
