Adherens junctions are specialized structures that help cells stick together, forming strong connections in tissues. They are primarily found in epithelial cells, which line surfaces in the body. These junctions consist of proteins called cadherins that connect to the actin cytoskeleton inside the cell, providing mechanical strength and stability. These junctions play a crucial role in maintaining tissue integrity and facilitating communication between cells. They are essential for processes like embryonic development and wound healing, as they help cells coordinate their activities and maintain proper tissue architecture.
