Cell adhesion is attachment of a biological cell to another cell or to its surroundings through molecular interactions. Adhesion strength and turnover help determine how cells transmit forces and rearrange.
A cell-cell junction coupling adhesion to the cytoskeleton. It can transmit mechanical load while being remodelled during epithelial movements.
A focal adhesion is a multiprotein connection between integrins and the actin cytoskeleton. It can transmit traction and change its assembly in response to loading.
