Abstract: The present invention is to provide a 3D cartilage organoid block prepared by differentiating mesenchymal stem cells into 3D spheroid cartilage tissues, a basic unit for the 3D cartilage spheroid block. The inventors found that both the amount of GAG matrix and the expression of the collagen type2 increased. Therefore, the method of this invention provides clinically applicable cartilage tissues by effectively enhancing the function of the cartilage differentiation constructs according to 2D culture. The 3D cartilage organoid block can be usefully applied to the area, such as, articular cartilage regeneration and plastic surgery, where cartilage tissues restoration is required.

Abstract: The present invention relates to a complex for promoting cartilage differentiation comprising stem cells or a culture thereof and a cartilage cell-free crush, a method for fabricating cartilage by using the complex, cartilage fabricated via the method, a pharmaceutical composition comprising the complex for preventing or treating arthropathy, a method for preventing or treating arthropathy using the composition, a composition for inducing cartilage cell differentiation comprising the prepared cartilage cells, and a method for fabricating cartilage using the prepared cartilage cells.

Abstract: The present invention relates to a method of manufacturing an animal cartilage-derived injectable composition, an injectable composition manufactured by the method, and a use thereof. The injectable composition of the present invention includes a collagen-containing biomaterial in a formulation injectable into joint cavity and may induce cartilage tissue regeneration by repairing tissue via direct injection to a target region without surgical incision. In addition, the injectable composition may be used as a therapeutic agent for arthritis by alleviating osteoarthritis not only because the animal cartilage-derived extracellular matrix contained in the injectable composition protects articular cartilage tissue but also because an environment capable of regenerating damaged articular tissue is created by inducing differentiation of intra-articular stem cells into chondrocytes.

Abstract: Disclosed is a method for producing a stem cell with enhanced efficacy, a stem cell produced thereby, and a method for treating a disease using the same. According to the present invention, sizes of stem cells may be reduced and proliferation ability, differentiation potency, migration ability, and angiogenic potential of stem cells may be significantly enhanced by applying a culturing method provided herein. Thus the present invention may be usefully applied to development of therapeutic agents using stem cells.
