Intra‐Articular Injection of Autologous Adipose Tissue‐Derived Mesenchymal Stem Cells for the Treatment of Knee Osteoarthritis: A Phase IIb, Randomized, Placebo‐Controlled Clinical Trial
Woo‐Suk Lee, et al., STEM CELLS Translational Medicine

 

This study found that rapamycin‐activated autophagy could protect cartilage endplate (CEP) from inflammation‐induced degeneration in a mouse model. Moreover, this study demonstrated that rapamycin‐activated autophagy promotes the expression of antioxidant proteins, thus affecting scavenging ROS, reducing cell senescence, and maintaining the differentiation potential of cartilage endplate stem cells (CESCs). Nrf2/Keap1 signaling is a pivotal pathway in controlling the expression of antioxidant proteins, and it was found that activation or inhibition of autophagy affects the expression and nuclear translocation of Nrf2, thus mediating CEP degeneration induced by TNF‐α. These findings are beneficial for the prevention of disease and for the development of clinical therapies.
