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.
Heart valves separate the atria from the ventricles, or the ventricles from a blood vessel. Heart valves are situated around the fibrous rings of the cardiac skeleton. The valves incorporate leaflets or cusps, which are pushed open to allow blood flow and which then close together to seal and prevent backflow.
