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. The complex for promoting cartilage differentiation comprising the stem cells or the culture thereof and the cartilage cell-free crush provided in the present invention is not only differentiated into cartilage cells without side effects even in vivo, but also promotes differentiation of inherent stem cells in vivo into cartilage cells via a paracrine effect exhibited in the differentiated cartilage cells to effectively regenerate the damaged cartilage, and thus the complex may be widely used for treatment of arthropathy involving the cartilage damage.
