MOVAS Cells

The MOVAS cell line is a murine vascular smooth muscle cell (VSMC) line derived from the aortic smooth muscle cells of C57BL/6 mice. This immortalized cell line retains key smooth muscle characteristics, making it a valuable tool for studying VSMC biology and pathophysiology. MOVAS cells have been extensively used in research on vascular processes such as atherosclerosis, calcification, and cellular signal transduction. They express characteristic smooth muscle markers, including alpha-smooth muscle actin (α-SMA), and can be cultured under various experimental conditions to model vascular diseases.

One of the major applications of MOVAS cells is in the study of vascular calcification. This cell line can undergo calcification in vitro when cultured in calcifying media containing β-glycerophosphate and ascorbic acid, mimicking processes observed in primary VSMCs. MOVAS cells exhibit elevated alkaline phosphatase activity and calcium deposition, which are key markers of vascular calcification. This model has also been validated against primary murine aortic VSMCs, showing comparable responses to calcifying conditions and treatments with known inhibitors like levamisole and etidronate. These features establish MOVAS as a reliable and cost-effective alternative to primary VSMCs, reducing experimental variability and ethical concerns.

Additionally, MOVAS cells have been used to explore cholesterol metabolism, a process critical to atherosclerosis development. They express essential cholesterol transporters such as ABCA1 and ABCG1, and exhibit functionality in cholesterol efflux to HDL and apoAI. Cholesterol-loading experiments have demonstrated their ability to transdifferentiate into macrophage-like cells, a process linked to atherosclerotic plaque formation. These findings highlight the utility of MOVAS cells in studying cholesterol homeostasis, phenotypic plasticity, and vascular disease progression.
