Potential origin of cells that contribute to valve calcification and fibrosis. Valve interstitial cells (VICs) are the main cellular component of the aortic valve. In interstitial cells, activated myofibroblasts are likely to arise from either quiescent VICs or a subpopulation of endothelial cells that undergo endothelial to mesenchymal transformation (EMT). RANKL increased the matrix calcification, ALP activity, and activation of the osteoblast transcription factor runx2 in cultured human aortic valve myofibroblasts. OPG prevents the interaction of RANKL with its receptor, RANK
