| Outline of Final Research Achievements |
Meniscal injury is treated with suture or partial meniscectomy in Japan, however irreparable injury has still to be investigated for the novel surgical technique because it goes osteoarthritic changes dramatically. Heparansulfate 6-O endosulfatases (Sulfs) had reported to be the essential factor for cartilage homeostasis and therapeutic potential for OA. In this research, We investigated the role of Sulf-1 in meniscus by using KO mice and its mechanism. As the result, Sulf-1 was associated with the meniscus homeostasis and type II collagen expression was reduced in Sulf-1 KO menisci. TGF/Smad cell signaling was accelerated with Sulf-1 supplementation, which overexpressed type II collagen. As the next step, novel meniscus therapy by using scaffold has been developed. We Scaffold involving Sulf-1 function may have a therapeutic potential in the near future.
