The Extracellular Matrix

Overview
In order to maintain tissue organization, many animal cells are surrounded by structural molecules that make up the extracellular matrix (ECM). Together, the molecules in the ECM maintain the structural integrity of tissue as well as the remarkable specific properties of certain tissues.
Composition of the Extracellular Matrix
The extracellular matrix (ECM) is commonly composed of ground substance, a gel-like fluid, fibrous components, and many structurally and functionally diverse...

Extracellular Matrix

Unlike epithelial tissue, which is composed of cells closely packed with little or no extracellular space in between, connective tissue cells are dispersed in a matrix. This extracellular matrix (ECM) is composed of fibrous proteins like collagen, elastin, and fibronectin in a ground substance consisting of interstitial fluid, cell adhesion proteins, and proteoglycans. The proteoglycans form a gel-like material in the spaces between cells and provide hydration, buffering, binding, and force...

Introduction to Fibroblasts

Rudolph Virchow discovered spindle-shaped cells called fibroblasts in 1858. Inactive fibroblasts, called fibrocytes, become activated by various stimuli, such as growth factors and inflammatory cytokines. Activated fibroblasts play a crucial role in wound healing, inflammation, formation of new blood vessels, and cancer progression. Uncontrolled activation of fibroblasts results in fibrosis, the excess deposition of fibrous tissue, which can lead to scarring and affect normal organs. This...

Overview of Cell-Matrix Interactions

10.0K
The extracellular matrix or ECM holds cells together to form a tissue and allows the cells within the tissue to communicate. ECM comprises proteins such as fibronectin, collagen, laminin, etc. The most abundant protein in this space is collagen. Collagen fibers are interwoven with carbohydrate-containing protein molecules called proteoglycans. ECM allows cell migration and provides a structural scaffold at cell adhesion that anchors the cell when the extracellular matrix proteins interact with...

Cell-matrix's Response to Mechanical Forces01:13

Cell-matrix's Response to Mechanical Forces

3.8K
In animal cells, the extracellular matrix allows cells within tissues to withstand external stresses and transmits signals from the outside of the cell to the inside. The extracellular matrix is extensive, and its composition varies between different types of tissues. For example, the reticular fibers and ground substance make up the ECM in loose connective tissue, while collagen and bone minerals make up the ECM of bone tissue. 
Anchoring junctions mechanically attach a cell to the...

Area of Science:

  • Biomedical Engineering
  • Cell Biology
  • Pulmonary Medicine

Background:

  • The extracellular matrix (ECM) is crucial for tissue structure and organ function.
  • Lung ECM provides physical support and contextual cues influencing cell behavior in health and disease.
  • ECM properties like stiffness and composition are vital for normal lung function.

Purpose of the Study:

  • To investigate the role of lung extracellular matrix (ECM) in tissue repair and disease progression.
  • To explore how alterations in ECM stiffness and composition affect fibroblast behavior.
  • To assess the implications of ECM properties for mesenchymal stromal cell-based therapies in lung disorders.

Main Methods:

  • Analysis of ECM composition and stiffness in healthy, injured, and diseased lung microenvironments.
  • Investigating fibroblast responses to varying ECM properties.
  • Evaluating the impact of pathological ECM on progenitor cell therapeutic potential.

Main Results:

  • Altered ECM composition and stiffness in injured or diseased lungs influence fibroblast reparative processes.
  • Pathological ECM stiffening or softening can precede and result from cell behavior changes.
  • Dysfunctional ECM can subvert the therapeutic intent of mesenchymal stromal cells.

Conclusions:

  • Lung ECM actively contributes to both normal physiology and pathological conditions.
  • Mediators of cell-ECM signaling and factors affecting ECM stiffness are potential therapeutic targets for lung diseases.
  • Understanding ECM's role is critical for developing effective lung disorder treatments.
