(noun)

All the connective tissues and fibers that are not part of a cell, but rather provide support.

Examples of extracellular matrix in the following topics:

  • Biofilms

    • These cells are frequently embedded within a self-produced matrix of extracellular polymeric substance (EPS).
    • Biofilm EPS, also referred to as slime, is a polymeric conglomeration composed of extracellular DNA, proteins, and polysaccharides.
    • Enzymes that degrade the biofilm extracellular matrix, such as dispersin B and deoxyribonuclease, may play a role in biofilm dispersal.
    • Biofilm matrix-degrading enzymes may be useful as anti-biofilm agents.
    • One benefit of this environment is increased resistance to detergents and antibiotics, as the dense extracellular matrix and the outer layer of cells protect the interior of the community.
  • Biofilms, Persisters, and Antibiotic Tolerance

    • They are characterized by structural heterogeneity, genetic diversity, complex community interactions, and an extracellular matrix of polymeric substances.
    • They live on solid surfaces (e.g., catheters, ) and the extracellular material they produce protects them from external threats, such as attacks by the body's immune cells.
  • Injuring the Plasma Membrane

    • It serves as the attachment surface for several extracellular structures, including the cell wall, glycocalyx, and intracellular cytoskeleton.
    • The plasma membrane also plays a role in anchoring the cytoskeleton to provide shape to the cell and in attaching to the extracellular matrix and other cells to help group cells together to form tissues .
  • Pili and Pilus Assembly

    • Other fimbriae bind to components of the extracellular matrix.
  • Extracellular Immune Avoidance

    • These adherent cells are frequently embedded within a self-produced matrix of extracellular polymeric substance (EPS).
    • Biofilm EPS, which is also referred to as slime, is a polymeric conglomeration generally composed of extracellular DNA, proteins, and polysaccharides.
  • Biofilms and Infections

    • These adherent cells are frequently embedded within a self-produced matrix of extracellular polymeric substance (EPS).
    • Dental plaque is a biofilm that adheres to teeth surfaces and consists of bacterial cells, salivary polymers, and bacterial extracellular products.
  • Starvation-Induced Fruiting Bodies

    • Individuals benefit from aggregation as it allows accumulation of extracellular enzymes which are used to digest food that increases feeding efficiency.
    • This behavior facilitates predatory feeding, as the concentration of extracellular digestive enzymes secreted by the bacteria increases.
  • The Deltaproteobacteria

    • Individuals benefit from aggregation as it allows accumulation of extracellular enzymes which are used to digest food.
  • Macrophages

    • Where a pathogen is involved, they are commonly preceded by neutrophils, which release a range of toxic agents designed to kill extracellular pathogens.
  • Alteration of Membrane Permeability

    • The periplasm contains the peptidoglycan layer and also many proteins responsible for substrate binding or hydrolysis and the reception of extracellular signals.
    • Na+) to travel through unrestricted and thereby destroy the ion gradient between the cytoplasm and the extracellular environment.
