ABSTRACT:
To obtain an artificial cartilage tissue having high strength and biocompatibility. There is provided an artificial cartilage tissue which is substantially free of heterologous protein and is substantially free of scaffold derived from non-cartilage-derived cells, but contains mammalian cartilage-derived cells and an extracellular matrix formed by the cartilage-derived cells, where: (1) the water retention per mg of tissue dry weight is 17.8 mg or less; (2) collagen of 5.57 μg or more per mg of tissue wet weight is contained; (3) proteoglycan of 9.22 μg or more per mg of tissue wet weight is contained.
