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

An Introduction to Aging and Regeneration
0 Views •
2023
Tissues are maintained through a balance of cellular aging and regeneration. Aging refers to the gradual loss of cellular function, and regeneration is the repair of damaged tissue generally mediated by preexisting adult or somatic stem cells. Scientists are interested in understanding the biological mechanisms behind these two complex processes. By doing so, researchers may be able to use somatic stem cells to treat degenerative diseases and develop therapies that could delay the effects of...

In newt, the lens regenerates always from the dorsal iris by transdifferentiation of the iris pigmented epithelial cells (IPEs). Here we describe a procedure to culture dorsal and ventral newt IPE cells and their implantation to the newt eye. The implanted cells are then studied by tissue sectioning and immunohistochemistry.

Sutures of the Skull

2025
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures. Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
FAQs
Successful restoration depends on a coordinated sequence rather than a single event. Hemostasis first helps control the wound, followed by inflammation, fibroblast proliferation, collagen deposition, and tissue remodeling. Because these stages contribute different biological functions, disruption or poor coordination can affect how well structural continuity and normal tissue function return after repair.
Fibroblast proliferation supplies cells involved in rebuilding the injured region, while collagen deposition contributes to the developing tissue framework. Remodeling then changes and organizes that repair over time. Together, these processes help convert an initially stabilized wound into tissue with greater structural integrity, making them important targets when healing strength and quality are evaluated.
Sutures and other closure materials provide mechanical stabilization while new tissue forms. This support helps maintain wound stability during the biological phases of repair, but successful healing also depends on integration with surrounding tissue. For biomaterial design, the relevant goals therefore include supporting stronger healing, improving tissue integration, and limiting excessive scarring.
At a basic level, repair must first use sutures or another closure material to stabilize the wound, then allow the healing sequence to proceed through inflammation, fibroblast proliferation, collagen deposition, and remodeling. The desired endpoint is not closure alone: researchers and clinicians also consider restored tissue function, structural integrity, integration with nearby tissue, and reduced complications.
It becomes especially relevant when the goal extends beyond wound closure. Studies may examine healing after trauma, surgery, or procedures involving specialized anatomical sutures, with attention to how well tissue regains strength and function. The topic also guides regenerative-medicine research seeking improved integration and less scarring after repair.
Evaluation centers on whether the repaired region regains structural integrity and function while avoiding complications. Research may also focus on the strength of healing, the degree of integration with surrounding tissue, and the amount of scarring. These outcomes connect healing processes such as collagen deposition and remodeling with meaningful recovery after injury or surgery.
