| Outline of Final Research Achievements |
Adipose-derived stem cells (ADSCs) can easily be isolated from subcutaneous adipose tissue and cultured in large quantities with a minimally invasive procedure. So, our study team has investigated them in various fields such as bones, cartilages, peripheral nerves, menisci and ligaments. The purpose of this study was to determine whether intra-articularly injected ADSC sheets inhibited articular cartilage degeneration during osteoarthritis(OA) development in a rabbit anterior cruciate ligament transection (ACLT) model.
Our study showed that the OA progression was milder in the ADSC sheets group. Furthermore, collagenases (MMP-1, MMP-13) and aggrecanase (ADAMTS-4) were less expressive in the same group. So, we suggested that the ADSCs inhibited progression of articular cartilage degeneration by secreting liquid factors having chondro-protective effects. To the best of our knowledge, our study is the first to prove the role of ADSC sheets in the treatment of OA.
