Cell Adhesion and Extracellular Matrix
Cell adhesion molecules and the extracellular matrix provide structural support, mediate cell-cell communication, and regulate tissue organization, migration, and signaling.
Cell Membrane Structure and Transport
The cell membrane is a selective permeability barrier composed of a phospholipid bilayer with embedded proteins, controlling the passage of molecules via passive and active transport mechanisms.
Cell Signaling and Signal Transduction
Cell signaling is the process by which cells communicate with each other through signaling molecules, receptors, and intracellular transduction cascades.
