Summary
Researchers developed a collagen multifilament wet-spinning process to create yarns for tissue engineering scaffolds. These collagen yarns mimic natural structures and can be processed using textile techniques like knitting.
Area of Science:
- Biomaterials Engineering
- Tissue Engineering
- Textile Science
Background:
- Collagen scaffolds offer tunable structures for tissue engineering.
- Current collagen spinning methods produce monofilaments, limiting textile applications.
- Multifilament yarns are crucial for advanced scaffold fabrication.
Purpose of the Study:
- To develop a reproducible collagen multifilament wet-spinning process.
- To characterize the properties of non-crosslinked and crosslinked collagen multifilament yarns.
- To demonstrate the textile processability of the developed collagen yarns.
Main Methods:
- Wet-spinning of collagen to produce multifilament yarns (6 filaments, 5 tex each, 80 μm diameter).
- Characterization of yarn properties, including tensile strength and Young's modulus (dry and wet states).
- Assessment of filament morphology using microscopy and demonstration of knitting technology.
Main Results:
- Successfully developed a reproducible collagen multifilament wet-spinning process.
- Glutaraldehyde crosslinked yarns exhibited tensile strength of 169 MPa (dry) and 40 MPa (wet).
- Collagen filaments displayed a fibrillar structure similar to natural collagen fibers, suitable for textile processing.
Conclusions:
- The developed wet-spinning process enables the production of collagen multifilament yarns for tissue engineering.
- Crosslinked collagen yarns possess mechanical properties suitable for scaffold applications.
- The fibrillar structure and textile processability open new avenues for collagen-based biomaterials.

01:11Fibril-associated Collagen
3.2K
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...

00:55Fibrous Proteins
4.0K
Fibrous proteins are either long and narrow proteins or assemble to form long and thin structures. They contain repetitive units and usually consist of either alpha helices or beta sheets and, in rare cases, a mix of both. The amino acids in the primary structure often consist of repeating amino acid sequences. The role of fibrous proteins is primarily structural. Many are located in the extracellular matrix and are present in connective tissues to impart strength and joint mobility. They are...

01:05Type IV Collagen of Basal Lamina
2.9K
Type IV collagen is a 400 nm long, network-forming collagen that acts as a barrier between the epithelial and endothelial cells. Type IV collagen forms the backbone of the basement membrane by scaffolding with laminin, entactin, proteoglycans, and fibronectin. Apart from rendering structural support to the basement membrane, it also helps entail signaling potentials necessary for both pathological and physiological functions.

01:13Collagens are the Major Structural Proteins of ECM
5.5K
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.

Structural proteins are a category of proteins responsible for functions ranging from cell shape and movement to providing support to major structures such as bones, cartilage, hair, and muscles. This group includes proteins such as collagen, actin, myosin, and keratin.
Collagen, the most abundant protein in mammals, is found throughout the body. In connective tissue, such as skin, ligaments, and tendons, it provides tensile strength and elasticity. In bones and teeth, it mineralizes to...

01:18Assembly of Cytoskeletal Filaments
27.0K
Cytoskeletal filaments are polymeric forms of smaller protein subunits. However, individual cytoskeletal filaments may easily disassemble or associate with other similar filaments to form rigid structures. Microfilaments, made of actin monomers, rely on actin-binding proteins to form bundles and create networks of individual actin filaments. Microtubules rely on microtubule-associated proteins (MAPs) to form sturdy cylindrical structures. However, the proteins involved in forming complex...
