Abstract: The present invention relates to a method for producing a cartilage model, comprising the step of simultaneously culturing a porous natural polymer support and a cartilage cell; a cartilage model produced by the method; and a method for testing the activity or toxicity of a test substance, comprising the step of treating the cartilage model with the test substance. A mature cartilage or aged cartilage model that can substitute an animal model may be produced using the method for producing the cartilage model according to the present invention, and the effectiveness and safety of the test substance may be accurately verified using the cartilage model thus produced, and thus, the cartilage model may be diversely utilized in the fields of new medicine development, disease research, and artificial organ development.
