Membrane-free stem cell components (MFSCC) from basal adipose tissue-derived stem cells (ADSCs) are unknown for the treatment strategies in osteoarthritis (OA). OA has been considered to be associated with inflammatory damage and cartilage degradation. In this study, we intended to investigate the molecular mechanism of the anti-inflammation and cartilage protection effect of MFSCC in vitro (rat primary chondrocytes) and in vivo (rat OA model). The MFSCC treatment significantly inhibited interleukin-1α (IL-1α) stimulated inflammation and cartilage degradation. The MFSCC considerably reduced the levels of inflammatory factors such as iNOS, COX-2, NO, and PGE2 and was suppressed NF-κB and MAPKs signaling pathways in IL-1α-stimulated rat chondrocytes. Additionally, biomarkers of OA such as MMP-9, COMP, and CTX-II decreased in the monosodium iodoacetate (MIA)-induced rat OA model by MFSCC treatment. In conclusion, the MFSCC was established to suppress IL-1α induced inflammation and cartilage degradation in vitro and in vivo. These findings provide new insight for understanding OA therapy using membrane-free stem cell approaches. View Full-Text
