And by decreasing the amount of cell adhesion molecules between these cells, these cells are able to actually detach from one another and they can move away from one another once they actually detach. And so, by decreasing the amount of cell adhesion molecules, we can eventually form these two structures. So remember, this eventually forms the Umbilical vesicle, also known as our yolksack. And this eventually forms the blue cells eventually form our Ambion in which we have the actual embryo that developing embryo. So Saladesian is a very important process that takes place within morphogenesis and cell to cell adhesion is affected by these morphogens. Now, what about the other thing that these proteins can actually do?
