Honors Theses
Cardiovascular disease is the leading cause of death in the United States with one of the major contributors being vascular calcification, characterized by the deposition of calcium-phosphate hydroxyapatite. Once thought to be a passive process due to aging, medial vascular calcification is becoming better understood as a tightly regulated, cellmediated process. Vascular smooth muscle cells (VSMCs) within the medial arterial layer respond to inflammation, oxidative stress, and changes in pyrophosphate levels, which induce differentiation into osteoblast-like cells. Fibroblasts within the adventitial layer (AFBs) also alter their function in response to vascular calcification signaling, although this is largely understudied. The AGE/RAGE …
