Cell–cell interaction

Cell–cell interaction refers to the various ways in which cells communicate, interact, and influence each other's behavior within a tissue or organism. These interactions are crucial for a wide range of biological processes, including development, immune responses, tissue repair, and homeostasis. There are several key mechanisms through which cell–cell interactions occur: 1. **Direct Contact**: Cells can interact through direct physical contact, where proteins on the surface of one cell bind to receptors on another.
