Cell-matrix's Response to Mechanical Forces01:13

Cell-matrix's Response to Mechanical Forces

2.7K
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...

Overview of Cell-Matrix Interactions

8.0K
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...

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...

Area of Science:

  • Biomaterials Science
  • Tissue Engineering
  • Regenerative Medicine

Background:

  • Acellular matrix (ACM) scaffolds are crucial for tissue regeneration.
  • Modifying ACM properties enhances their performance in regenerative medicine applications.

Purpose of the Study:

  • To review current crosslinking strategies for ACM scaffolds.
  • To provide a foundation for future experimental research in scaffold modification.

Main Methods:

  • Literature review of recent publications from PubMed and Web of Science.
  • Keywords used included 'crosslinking' and related terms.

Main Results:

  • Chemical crosslinking uses synthetic or natural agents, requiring removal due to potential biotoxicity, though less toxic options exist.
  • Physical crosslinking is safe, additive-free, and controllable for surface functionalization without radioactivity concerns.
  • Biological crosslinking is gaining interest for collagen-based scaffolds, offering non-toxic, physiological condition preparations.

Conclusions:

  • Multiple crosslinking methods effectively modify ACM, showing promising performance for tissue and organ substitutes.
  • Further preclinical and clinical evaluations are necessary to confirm the safety and efficacy of modified ACM in regenerative medicine.
