Figure 3: Adipogenesis versus osteogenesis in ectopic calcification. Induction ofcommon vascular progenitor cells lead to differentiation of cells to either endothelial, pericytes or smooth muscle cells. Pricytes myofibroblasts are also derived from different progenitor cells and fibroblasts. Myofibroblasts have the ability to follow either the adipogenesis or the osteogenesis pathways.
