This video demonstrates the induction of intestinal graft-versus-host disease, GvHD, in a lethally-irradiated recipient mouse using allogeneic hematopoietic stem cells and GvHD-inducing splenic alloreactive T lymphocytes. This protocol helps establish a severe acute intestinal GvHD model to understand the mechanism of the disease and develop innovative therapeutic options.

Microhardness is a mechanical property and an informative parameter for evaluating hard tissue pathophysiology. Here, we demonstrate a standardized protocol (sample preparation, polishing, flat surface, and indentation sites) for microhardness analysis in tooth and alveolar bone in rodent oral disease models, namely, dental fluorosis, and ligature-induced periodontal bone resorption.

This video describes the technique of surgically inducing bacterial infection in the bone marrow of a rabbit by using bone wax to avoid the leakage of bacteria. This rabbit model can be used to study bone infection treatment and bone regeneration.
FAQs
Osteoblasts model bone formation, whereas osteoclasts model bone resorption. Examining these cell types separately or in relation to one another helps researchers determine whether a disorder is associated with reduced formation, excessive resorption, or an imbalance between both processes. This distinction connects cellular behavior with broader changes in skeletal tissue.
Each type of change can reproduce a different source of abnormal bone remodeling. Genetic changes can represent disease-associated alterations, biochemical changes can modify cellular behavior, and mechanical changes can mimic environmental influences on skeletal tissue. Comparing these conditions helps link specific pathways or inputs to weakened architecture, reduced formation, or excessive resorption.
These systems represent disease features at different biological and structural levels. Cultured osteoblasts or osteoclasts emphasize cellular mechanisms, engineered tissues provide a tissue-level setting, and animals allow skeletal disorders to be examined within a broader biological system. Using more than one model can connect molecular or cellular findings with tissue architecture and overall skeletal outcomes.
A useful model should reproduce the disease feature most relevant to the research question, such as altered bone formation, excessive resorption, or weakened tissue architecture. Researchers can then select a cellular, engineered-tissue, or animal system and introduce an appropriate genetic, biochemical, or mechanical change. This alignment improves the connection between the model and the disorder being studied.
Researchers use controlled disease-like changes to connect abnormal cellular behavior with disease-associated pathways. If a pathway is linked to reduced formation, excessive resorption, or structural weakening, it may become a candidate target for further investigation. The model therefore helps move from observing a skeletal defect toward testing which biological processes might be modified.
After a model reproduces a relevant skeletal feature, researchers can evaluate how experimental treatments affect the associated cellular, molecular, or structural outcome. These systems also help examine how biological and environmental factors influence skeletal health, including factors represented through genetic, biochemical, or mechanical changes. Results can clarify both treatment effects and disease mechanisms.
