Termini in questo insieme (15)

  • Basal Lamina
    Thin extracellular matrix beneath cells, mainly epithelial, providing foundational support and composed of specific glycoproteins.
  • Epithelial Cells
    Polarized cells forming protective layers on surfaces and internal organs, relying on a specialized foundation for support.
  • Extracellular Matrix
    Network of proteins and molecules outside cells, offering structural and biochemical support to surrounding cells.
  • Laminin
    Trident-shaped glycoprotein crucial for binding cellular membranes to structural fibers in supportive tissue layers.
  • Type 4 Collagen
    Specialized collagen forming rope-like fibers, providing tensile strength within foundational cellular support layers.
  • Basement Membrane
    Composite structure beneath cells, containing multiple layers, with one key layer providing direct support to cell bases.
  • Plasma Membrane
    Cellular boundary interacting with external support structures, facilitating attachment via specific binding proteins.
  • Integrin
    Transmembrane protein connecting cellular membranes to external support matrices, mediating adhesion and signaling.
  • Schwann Cells
    Supportive cells in the nervous system, surrounded by specialized extracellular layers for structural reinforcement.
  • Polarization
    Characteristic of certain cells having distinct structural and functional sides, separated by unique protein compositions.
  • Apical Side
    Surface of a polarized cell facing away from the foundational support, often exposed to external environments.
  • Basal Side
    Surface of a polarized cell in direct contact with foundational support structures, anchoring the cell.
  • Glycoprotein
    Protein with attached carbohydrate groups, playing key roles in cell adhesion and structural organization.
  • Rope-like Matrix
    Structural arrangement formed by intertwined protein fibers, enhancing strength and stability in support layers.
  • Tight Junction
    Specialized connection between adjacent cells, maintaining separation of cellular sides and regulating passage.
