Outline of Final Research Achievements |
This study investigated to develop a clinical applicable DN gel implant and elucidated physical and biological factors regulating the DN gel-induced cartilage regeneration. (1) We developed a 0.5-mm thick gel implant. (2) We found that a 1.0-mm DN gel implant induced in vivo cartilage regeneration in a rabbit model. (3) We observed that DN gel induced in vivo cartilage regeneration regardless of location in which the DN gel was implanted in the joint. (4) We observed that DN gel induced in vivo cartilage regeneration regardless of the size of osteochondral defect. (5) We found that DN gel induced in vivo cartilage regeneration in a sheep model. (6) We found that the hyaluronic acid was a useful molecule to promote cartilage regeneration induced by DN gel.
