Certificate of Analysis. Human Cardiac Fibroblasts (HCF) Primary Human Cardiac Fibroblasts (HCF) are isolated from the ventricles of an adult heart. They play a central role in the maintenance of the extracellular matrix in the normal heart and the synthesis of growth factors and cytokines.
The aortic valve functions as a one-way valve between the heart and  the rest of the body. Blood is pumped from the left ventricle of  the heart, through the valve, and down â¦ the aorta, which in turn  supplies blood to all of the organs in the body.etween heart  contractions, the valve closes, preventing blood from flowing  backwards into the heart. The function of the aortic valve is then  twofold: (1) It provides a route for which blood can leave the  heart, and (2) It prevents blood that has already left the heart  from leaking backwards into the heart.
