    • PROBLEM TO BE SOLVED: To provide a method for inducing proliferation and differentiation of a cartilage cell or increasing cartilage substrate production by administering the effective dose of a RANKL binding molecule that acts on a cartilage precursor cell and/or a mesenchymal stem cell to promote cartilage differentiation, proliferation and maturity of these cells, reinforce the differentiation of the cartilage cell, and cause the proliferation of the cartilage cell; and a drug composition for inducing the proliferation and the differentiation of the cartilage cell or increasing the cartilage substrate production.SOLUTION: A drug composition for treating or preventing a cartilage metabolism disease includes a compound that acts on a cartilage precursor cell and/or a mesenchymal stem cell to cause at least one selected from among (a) promotion of differentiation of the cartilage precursor cell and/or the mesenchymal stem cell, (b) promotion of proliferation of the cartilage precursor cell and/or the mesenchymal stem cell, (c) promotion of maturity of the cartilage precursor cell and/or the mesenchymal stem cell, (d) reinforcement of differentiation of a cartilage cell, (e) proliferation of the cartilage cell and (f) an increase in cartilage substrate production as an active ingredient.
    • 要解决的问题:提供一种通过施用有效剂量的作用于软骨前体细胞和/或间充质干细胞以促进软骨的RANKL结合分子的软骨细胞增殖和分化或增加软骨底物产生的方法 这些细胞的分化,增殖和成熟,增强软骨细胞的分化,并引起软骨细胞的增殖; 以及用于诱导软骨细胞的增殖和分化或增加软骨底物产生的药物组合物。解决方案:用于治疗或预防软骨代谢疾病的药物组合物包括作用于软骨前体细胞和/或间充质的化合物 (a)促进软骨前体细胞和/或间充质干细胞分化的至少一种,(b)促进软骨前体细胞和/或间充质干细胞的增殖,(c 促进软骨前体细胞和/或间充质干细胞的成熟,(d)加强软骨细胞的分化,(e)软骨细胞的增殖和(f)作为活性成分的软骨底物生产的增加 。
