The proposed pathway of ACV formation in articular chondrocytes. Articular chondrocytes display ongoing autophagy and low levels of ACV formation and release. Factors which increase autophagy produce increased numbers of autophagosomes, which are released as extracellular ACVs in a caspase- and Rho/ROCK- dependent process.
