And that can essentially affect the process of cell to cell adhesion. And cell to cell adhesion is the process by which cells bind and attach to other cells. So let's focus for now on cell adhesion. So cells can bind to one another by using a special type of molecule found on the membrane known as the cell adhesion molecule or CA M. Now, it turns out that morphogens can influence the way that cells attach to other cells by expressing different types of calm molecules on the membrane of those cells. In fact, it turns out that the reason one cell binds to another cell is because they have the same type of Cam molecules. So cells tend to aggregate and form groups because they contain the same exact cell adhesion molecule on the membrane.
