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.

A novel technique to create a reproducible in vivo model of cervical spinal cord laceration injury in the mouse is described. This technique is based on spine stabilization by fixation of the cervical facets and laceration of the spinal cord using an oscillating blade with an accuracy of ±0.01 mm.

Sutures of the Skull

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...

Ischemia-reperfusion Model of Acute Kidney Injury and Post Injury Fibrosis in Mice

We describe models of moderate and severe ischemia-reperfusion-induced kidney injury in which the mice undergo unilateral renal pedicle clamping followed by simultaneous or delayed contralateral nephrectomy, respectively. These models consistently give rise to renal dysfunction and post-injury fibrosis, but injury severity and survival are dependent on mouse background, age and surgical equipment.
FAQs
Repair unfolds through coordinated stages rather than a single response. Inflammation is followed by cell proliferation, extracellular-matrix remodeling, and osteogenic signaling, which promotes bone-forming activity. The sequence allows researchers to examine how damaged cranial tissues reorganize and whether repair preserves the suture’s growth-related function or shifts the region toward replacement by bone.
The balance determines whether the injured region continues to accommodate skull growth or becomes progressively replaced by bone. Stronger osteogenic activity can encourage tissue mineralization, whereas coordinated repair that preserves the suture supports continued separation between developing skull bones. This distinction makes injury sites useful for studying how normal development and abnormal fusion can diverge.
These processes provide complementary parts of the repair response. Inflammation initiates the reaction to damage, cell proliferation supplies new cellular activity, and extracellular-matrix remodeling changes the tissue environment in which repair occurs. Examining their coordination helps developmental biologists determine how cranial tissues respond to disruption before osteogenic signaling influences the longer-term structural outcome.
The model links a defined disruption to observable changes in repair and cranial growth. Mechanical or cellular disturbance may alter inflammation, proliferation, matrix remodeling, or osteogenic signaling, allowing investigators to study how those pathways interact. This provides a developmental context for analyzing why some injuries support organized regeneration while others may contribute to premature bony replacement.
Researchers should follow the major repair processes identified in the model: inflammation, cell proliferation, extracellular-matrix remodeling, and osteogenic signaling. They can then relate these responses to the tissue’s structural outcome, especially whether the suture remains open or becomes replaced by bone. This approach connects cellular activity with the broader pattern of postnatal cranial development.
The model shows how cranial tissues regenerate and coordinate bone growth after disruption, making it relevant to developmental mechanisms rather than repair alone. It also provides a way to investigate abnormal suture fusion, including processes relevant to craniosynostosis. Findings may guide research into strategies intended to restore more typical patterns of skull development.
