Cell adhesion

Cells in our body are like tiny building blocks that come in different shapes and sizes. They need to stick to each other and stay in a group to do their job properly. Just like how magnets attract each other, cells in our body use special molecules called adhesion molecules to stick to each other.

Think of adhesion molecules as glue that holds the cells together. These molecules have special shapes and hooks that interact with the surface of the other cell. Once they attach, they hold tight and keep the cells together.

Not all cells use the same type of adhesive molecules, and they may use different sets of molecules depending on where they are in the body. Some cells may also change the type of adhesive molecules they use when they need to move or do something different.

Without adhesion molecules, our cells would be like tiny LEGO bricks that just tumble around and couldn’t work together to make things happen. Cell adhesion is essential for keeping our body together and working properly!
