Silk fibers have been processed and used to create fabrics and threads for centuries. However, the solubilizing of silk fibers, thereby turning it into a versatile pre-polymer solution is a much newer technology. Solubilized silk can be processed in many different ways to create a biocompatible material with controllable mechanical properties. This video introduces the processing of silk from silk worm cocoons, and shows how the silk solution can be used to create a fiber mat via...

Despite the outstanding mechanical and biochemical properties of spider silks, this material cannot be harvested in large quantities by conventional means. Here we describe an efficient strategy to spin artificial spider silk fibers, which is an important process for investigators studying spider silk production and their use as next-generation biomaterials.

Blending is an efficient approach to generate biomaterials with a broad range of properties and combined features. By predicting the molecular interactions between different natural silk proteins, new silk-silk protein alloy platforms with tunable mechanical resiliency, electrical response, optical transparency, chemical processability, biodegradability, or thermal stability can be designed.

Q Suture Technique: A Suturing Technique to Reduce Gap Formation and Increase Tensile Strength in Tendon Repair

2025
In this video, we demonstrate suturing techniques — core suture and Q suture — to repair the foot flexor tendon in an ex vivo porcine model. Q sutures enhance the strength of the core suture in tendon repair and decrease gapping at the tendon repair site.
FAQs
Tightening the knot applies sustained mechanical compression to the selected vessel, duct, or tissue segment. That compression narrows or closes the structure, restricting fluid flow while helping stabilize the treated site. The resulting change in local circulation can then be examined as a controlled factor in tissue injury, inflammation, or infection studies.
Localized injury from the ligation can activate wound-healing and inflammatory responses at the treated site. In immunology research, this provides a defined setting for examining immune-cell recruitment and comparing how inflammation develops under different experimental conditions. The response is local initially, allowing investigators to relate cellular changes to a specific mechanically altered region.
Standardizing the silk material and the ligation site improves comparisons between experimental conditions. Researchers can therefore distinguish responses associated with altered circulation or tissue injury from differences caused simply by where the suture was placed or which material was used. This consistency is especially useful when examining inflammation, pathogen spread, or tissue repair across groups.
The procedure begins by identifying the biological structure or tissue segment to be controlled, followed by placing braided silk thread around the selected site. Tightening the knot creates the intended compression, occlusion, or stabilization. Keeping the target and ligation location consistent across samples supports reproducible interpretation of subsequent immune or infectious responses.
In infection models, controlled ligation can alter local circulation or create reproducible tissue injury before host responses are assessed. Investigators can use the resulting system to examine pathogen spread alongside immune-cell recruitment, inflammation, and tissue repair. Because the ligation can be standardized, experimental groups can be compared under more consistent local conditions.
Observations may include how immune cells are recruited, how inflammation develops, whether pathogen spread changes, and how the tissue repairs itself. These outcomes connect the mechanical intervention with host responses at the treated location. Comparing them across standardized ligation conditions helps reveal how altered circulation or localized injury influences immunological and infectious processes.
