A7r5 Cells

Derived from the smooth muscle of the embryonic thoracic aorta in a BDIx rat, the A7r5 cell line is extensively employed in cardiovascular research. These fibroblast-like cells display a unique flat ribbon-like morphology that transitions into parallel arrays of spindle-shaped cells as they differentiate. This distinct structural adaptation facilitates the study of cellular dynamics and morphology under various physiological conditions. During the stationary phase of their growth cycle, A7r5 cells exhibit a significant increase in the activities of myokinase and creatine phosphokinase (CPK), enzymes critical in cellular energy transfer and metabolism. The synthesis of a specific muscle type CPK isoenzyme upon cessation of cell division in A7r5 cells provides a valuable model for investigating molecular mechanisms underlying muscle development and differentiation. This cell line has been instrumental in exploring the effects of angiotensin II on vascular oxidative stress, offering insights into how this hormone influences cardiovascular physiology. Additionally, A7r5 cells have been used to study the inhibitory effects of phospholipase A2 (PLA2) on lipid droplet formation, further highlighting their utility in cardiovascular research. These applications underscore the A7r5 cell line's versatility and its pivotal role in elucidating critical pathways and potential therapeutic targets in cardiovascular disease studies.
