Cholestasis is a clinical condition commonly encountered by both surgeons and gastroenterologists. Creation of a reversible cholestatic rat model can be challenging in view of the smaller size and unique hepatopancreatobiliary anatomy in rats. This video article demonstrates the creation of a reversible cholestatic model.

We have developed a minimally invasive technique to create a rabbit ischemic ear wound model by dividing the central artery and nerve and the cranial neurovascular bundle. A subcutaneous tunnel then cuts all subcutaneous tissues. This procedure causes minimal skin disruption and can be safely used in diabetic animals.

Adipose-derived stem cells (ASCs) are easily isolated and harvested from the fat of normal rats. ASC sheets can be created using cell-sheet engineering and can be transplanted into Zucker diabetic fatty rats exhibiting full-thickness skin defects with exposed bone and then covered with a bilayer of artificial skin.
FAQs
Standardizing the wound’s round geometry and defined tissue area reduces variation caused by differences in size or shape. This allows investigators to compare healing rates more reliably across untreated controls, wound dressings, biomaterials, drugs, and regenerative therapies. Consistent starting conditions strengthen interpretation by making observed differences more likely to reflect the intervention or biological response.
Sequential observation can separate several features of repair, including wound contraction, re-epithelialization, granulation tissue formation, and remodeling. These processes represent different aspects of recovery, so monitoring them over time provides more information than a single endpoint. The resulting profile helps researchers determine whether an intervention affects closure, tissue formation, or later repair stages.
A circular template or biopsy punch guides removal of a defined tissue area and establishes a consistent starting geometry. This component is important because the initial wound dimensions directly affect later measurements of healing. Using a defined guide supports reproducible experimental groups and makes changes in wound appearance or closure easier to compare over time.
The workflow begins by using a circular guide to remove a defined area of tissue. Investigators then monitor the resulting defect over time, assessing changes associated with contraction, re-epithelialization, granulation tissue formation, and remodeling. This sequence produces measurements that can be used to compare healing behavior between experimental conditions or treatment groups.
This approach is useful when a study needs controlled comparisons of wound-healing responses. It can support evaluations of wound dressings, biomaterials, drugs, and regenerative therapies in experimental models. Because the wound geometry is standardized, investigators can examine whether a treatment changes the rate or pattern of repair under comparable starting conditions.
The method can provide time-dependent information about how quickly and in what manner a skin defect repairs. Researchers may follow contraction, re-epithelialization, granulation tissue formation, and remodeling while comparing experimental groups. In medicine, these outcomes help connect a candidate therapy with specific aspects of tissue injury and repair rather than relying only on a general healing impression.
