So we discussed the tissue factor. So we said that the tissue factor is basically a glycoprotein. So this is shown in green and this is, let's say, the cell membrane of some endothelial cell found in the blood vessel. So what this tissue factor does is it's actually a glycoprotein that basically interacts with other molecules, namely factor seven, to form a dimer complex. And this glycoprotein, this tissue fact, is actually used to initiate the blood clot and cascade, the formation of the blood clot. More specifically, it initiates the extrinsic pathway of that coagulation cascade.
