Abstract

Vascular calcification is common and clinically significant in atherosclerosis and heart failure. It was long believed to be an end-stage process of "passive" mineral precipitation. However, there is now a growing awareness that vascular calcification is a biologically regulated phenomenon. It has many similarities to bone formation, and ectopic bone is a well-documented part of vascular calcification. This implies that alterations in vascular cell differentiation, extensive or localized, are an integral part of vascular calcification. Matrix gamma-carboxylated glutamate (GLA) protein (MGP)-deficient mice develop extensive vascular calcification with replacement of the media by progressively calcifying cartilage. A potential mechanism that explains these findings is MGP interference with bone morphogenetic proteins-potent inducers of cartilage and bone.
