The growth plate is a cartilaginous region in children's long bones where longitudinal growth occurs. When injured, bony tissue can form and impair growth. We describe a rat model of growth plate injury that leads to bony repair tissue, allowing the study of repair mechanisms and growth plate regeneration strategies.

Here, we present the preparation of an er-xian decoction (EXD) in four steps—soaking, decoction, filtration, and concentration—and demonstrate the administration of a prepared EXD-containing serum to rats. These methods are applicable to the in vivo and in vitro study of herbal decoctions such as traditional Chinese medicines.
FAQs
Trabecular architecture changes through coordinated remodeling: osteoblasts form bone, whereas osteoclasts resorb it. This ongoing activity allows the internal framework to adjust during growth and in response to physical stress or activity. The balance between formation and resorption influences the persistence and organization of marrow-surrounding struts, making cellular remodeling central to skeletal adaptation.
The interconnected arrangement of trabeculae helps distribute mechanical loads through spongy bone while using relatively little tissue mass. Rather than relying on a solid block of bone, this internal framework surrounds marrow spaces and contributes to structural strength through its organization. Studying that architecture therefore helps explain how bone combines support with efficient use of material.
Growth, physical activity, and mechanical stress all influence the remodeling of trabeculae. These conditions affect the balance between bone formation by osteoblasts and resorption by osteoclasts, changing the internal framework over time. Because trabecular structure responds to these influences, altered loading or disease can produce important changes in tissue organization and skeletal condition.
In spongy bone, trabeculae maintain spaces that contain marrow while forming the surrounding internal framework. Preserving these spaces supports blood-cell production, linking skeletal architecture with a major biological function. Remodeling can therefore affect more than mechanical strength: changes in the organization of the struts may also alter the marrow-containing environment that supports hematopoiesis.
Research on trabeculae provides a way to examine how skeletal tissue changes in osteoporosis and how those changes relate to fracture risk. Investigators can focus on the internal architecture and its remodeling, then consider how disease or altered loading affects the framework. This connects microscopic tissue organization with broader questions about skeletal development, weakness, and injury.
Trabecular structures also occur in the spleen and parts of the heart, where they contribute to internal tissue frameworks. Considering these locations broadens the biological context beyond bone and shows that thin, branching structural elements can organize different tissues. Comparison across these sites helps researchers study how internal architecture supports the form of varied biological structures.
