title: [Differentiation of multipotent mesenchymal stromal cells of bone marrow into cells of cartilage tissue by culturing in three-demential OPLA scaffolds].
abstract: Bone marrow multipotent mesenchymal stromal cells represent a perspective material for engineering of human three-dimensional transplants of cartilage tissue. We are demonstrated the opportunity of the directed differentiation of BM MMSC in cells of cartilage tissue by culturing them in three-dimensional scaffolds, presented by polymer OPLA in medium with inductors of chondrogenesis. For loading cells in porous scaffolds used method which essence consist in saturation of polymeric blocks by cellular suspension with the subsequent centrifugal force of cells in scaffolds and culturing of engineering constructs for 28 days in chondrogenic medium. Histological analysis derived in vitro of three-dimensional transplants showed uniform distribution of cells in the matrix with morphologically distinct chondrocytes-like cells of hyaline cartilage. Immunohistochemical analysis detected aggrecan and collagen type II within the extracellular matrix. Preclinical the researches lead on a livestock of immunodeficient mice have shown not toxicity of the engineering constructs.
