Stable factor (English factor VII) is a protein that plays an important role in blood clotting in the human body. It belongs to the clotting factor family and is the seventh factor in the coagulation system.
The stable factor was discovered in 1954 by American scientists and got its name due to its ability to maintain stability during storage. It is the most stable coagulation factor of all seven. After its discovery, scientists began to conduct numerous studies to understand how it works.
One of the most important properties of a stable factor is its ability to control the rate of blood clot formation. When blood vessels are damaged, the coagulation system causes the formation of hemostatic threads inside the vessel, which control bleeding and prevent large blood losses. However, if the stable factor is inactive or its quantity decreases, the rate of formation of these threads becomes much slower, which can lead to serious bleeding and even death.
Scientific research shows that the stable factor is associated with genetic factors and can change
