Summary
Echinoderm collagen offers a novel source for tissue engineering. Echinoderm-derived collagen membranes (EDCMs) show promise for Guided Tissue Regeneration (GTR), particularly from sea urchins, offering eco-sustainability benefits.
Area of Science:
- Biomaterials Science
- Tissue Engineering
- Marine Biotechnology
Background:
- Marine collagens are gaining attention in tissue engineering.
- Mutable Collagenous Tissues (MCTs) from echinoderms are a unique collagen source.
- Collagen membranes are crucial for Guided Tissue Regeneration (GTR).
Purpose of the Study:
- To investigate echinoderms as a source for collagen barrier-membranes for GTR.
- To produce and characterize echinoderm-derived collagen membranes (EDCMs).
- To evaluate EDCMs' performance compared to commercial membranes and bovine collagen.
Main Methods:
- MCTs from sea urchin, starfish, and sea cucumber were used to create EDCMs.
- EDCMs were structurally and mechanically characterized.
- Fibroblast cell adhesion and morphology on EDCMs were assessed.
- Commercial GTR membranes and bovine collagen substrates served as controls.
Main Results:
- Three types of EDCMs exhibited similar structures and mechanical properties.
- EDCMs were thinner and mechanically stronger than commercial GTR membranes.
- Fibroblast cell seeding on sea urchin membranes was comparable to bovine collagen.
- Cell morphology on EDCMs resembled that on reassembled bovine collagen.
Conclusions:
- Echinoderms, especially sea urchins, are viable alternative collagen sources for GTR membranes.
- EDCMs demonstrate potential for effective Guided Tissue Regeneration.
- Utilizing sea urchin waste tissues offers an eco-sustainable approach to biomaterial production.

01:13Collagens are the Major Structural Proteins of ECM
6.2K
Three main types of fibers are secreted by fibroblasts: collagen fibers, elastic fibers, and reticular fibers. Collagen fiber is made from fibrous protein subunits linked together to form a long, straight fiber. Collagen fibers, while flexible, have great tensile strength, resist stretching, and give ligaments and tendons their characteristic resilience and strength. These fibers hold connective tissues together, even during the body's movement.

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...

37.7K
One of the significant functions of connective tissue is connecting tissues and organs. Unlike epithelial tissue that is composed of cells closely packed with little or no extracellular space in between, connective tissue cells are dispersed in a matrix. The matrix usually includes a large amount of extracellular material produced by the connective tissue cells that are embedded within it. It plays a significant role in the functioning of this tissue. The major component of the matrix is a...

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...

3.5K
Fibril-associated collagens are a type of collagens present in the extracellular matrix with interrupted triple helices or FACIT (Fibril-associated collagens interrupted triple-helices). FACIT help connect and attach the collagen fibrils with each other as well as with other proteins of the extracellular matrix.
For example, the type II collagen fibrils in cartilage have covalently bound type IX fibril-associated collagens at regular intervals. Other types of fibril-associated collagens are...
