The Extracellular Matrix

12.0K
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

5.2K
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...

Tumor Progression02:07

Tumor Progression

7.2K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

4.6K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

The Bone Matrix01:18

The Bone Matrix

5.5K
Bone contains a relatively small number of cells entrenched in a matrix of collagen fibers that provide an adherent surface for inorganic salt crystals. Both components of the matrix, organic and inorganic, contribute to the unusual properties of bone. Without collagen, bones would be brittle and shatter easily. Without mineral crystals, bones would flex and provide little support. This can be observed by an experiment: when the minerals of a bone are dissolved by soaking the bone in...

Summary
This summary is machine-generated.

Manufacturing hydrogels from human tissues for regenerative medicine is challenging due to tissue variability. Animal-derived extracellular matrix (ECM) hydrogels are more feasible for tissue engineering applications.

Area of Science:

  • Tissue Engineering
  • Regenerative Medicine
  • Biomaterials Science

Background:

  • Decellularized extracellular matrix (ECM) bioscaffolds are key biomaterials for synthetic tissue fabrication.
  • ECM-based hydrogels can be derived from animal or human tissues.
  • Clinical applications of human ECM hydrogels are limited due to scarce and inconclusive research.

Purpose of the Study:

  • To review current decellularization and hydrogel manufacturing strategies.
  • To highlight challenges in using human tissues for ECM hydrogel production.
  • To compare human and animal tissue sources for biomaterial development.

Main Methods:

  • Review of contemporary decellularization techniques.
  • Analysis of hydrogel manufacturing processes.
  • Comparative assessment of tissue sources (human vs. animal).

Main Results:

  • Hydrogel production from human tissues is complex and requires further development.
  • Interindividual variability (age, sex, ethnicity, health status) significantly impacts human tissue gelation.
  • Animal tissues offer more predictable characteristics for hydrogel manufacturing.

Conclusions:

  • Current methods for obtaining hydrogels from human tissues are still evolving.
  • Significant challenges exist in standardizing human ECM hydrogel production due to tissue heterogeneity.
  • Animal-derived ECM hydrogels currently present a more viable option for tissue engineering applications.
