Outline of Final Research Achievements

Twenty-four knees of 12 adult beagle dogs were randomly assigned to either group 1 (a single injection of 1 ml lactated Ringer’s solution), group 2 (a single injection of 5×106 cells synovium-derived MSCs (SMSCs) with 1 ml 0.01% hacid (HA)), group 3 (while 3 times injection group had a single injection of 5×106 cells SMSCs with 1 ml 0.01 % HA.) A partial thickness cartilage defect with 4 mm was created on medical femoral condylar.Group 2 and 3 were significantly greater than that of group 1. However, there was no significant difference between the group 2 and group 3.

Academic Significance and Societal Importance of the Research Achievements

近年、関節軟骨損傷モデルに対して間葉系幹細胞の関節内注射を行い、良好な軟骨再生を得たという基礎的研究の報告が散見される。しかしそれらの研究において、関節内注射の回数は様々であり、一定の見解はない。本研究の結果から、関節軟骨損傷に対する間葉系幹細胞の関節内注射において、単回投与と複数回投与の間に治療成績の差はない可能性が示唆された。すなわち、今後間葉系幹細胞を用いた再生医療が現実となった際、患者に対する不要な侵襲を避けるための根拠となる可能性がある。
