Bone metastasis models do not develop metastasis uniformly or with a 100% incidence. Direct intra-osseous tumor cell injection can result in embolization of the lung. We present our technique modeling primary bone tumors and bone metastasis using solid tumor graft implantation into bone, leading to reproducible engraftment and growth.

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.

In this video, we describe a method for the detection of osteoblast-secreted calcium deposits using an anionic dye, Alizarin Red S. The cultured osteoblasts are first stained and then the dye is recovered for colorimetric quantification of calcium deposits or the degree of osteoblast mineralization.

To improve our knowledge of cellular and molecular neotissue formation, a murine model of the TEVG was recently developed. The grafts were implanted as infrarenal vena cava interposition grafts in C57BL/6 mice. This model achieves similar results to those achieved in our clinical investigation, but over a far shortened time-course.

Animal models are frequently utilized to study cancer metastasis to bone. In this protocol we will describe two common methods of tumor inoculation for bone metastasis studies and briefly describe some of the analyses utilized to monitor and quantify these models.
FAQs
These properties shape how effectively cells and tissue interact with the material. Composition affects the substrate environment, porosity provides space for cell attachment, migration, vascular ingrowth, and mineral deposition, while degradation rate influences how long the supporting architecture remains available. Researchers therefore consider these variables together when designing substrates for integration and new bone formation.
A three-dimensional structure does more than provide physical support. It creates an osteoconductive surface where regenerative cells can attach and move, while also allowing vascular ingrowth and mineral deposition. Examining these interactions helps researchers determine whether a substrate can support organized tissue development and whether its architecture is appropriate for a particular regeneration strategy.
Osteoblast interactions provide a biological measure of how cells respond to the material. Researchers can examine whether these regenerative cells attach to the substrate and participate in processes associated with mineral deposition. Such observations help connect material design with tissue-forming behavior, guiding improvements in graft architecture, composition, and expected healing performance.
A typical investigation begins by selecting or engineering a substrate with defined architectural and compositional features. Researchers then examine how osteoblasts or other regenerative cells interact with it, including attachment, migration, and mineral deposition. Comparing these responses across substrate designs helps identify characteristics that may improve integration, bone regeneration, or implant fixation.
The choice depends on the research goal and the properties being investigated. Natural substrates can serve as biological materials for studying regeneration, whereas engineered substrates allow researchers to examine how designed composition, porosity, and degradation behavior affect cell interactions. Both approaches can support evaluation of graft performance, implant fixation, or delivery strategies at defect sites.
These studies can reveal how material features influence cellular behavior and tissue integration. Measurements or observations related to cell attachment, migration, vascular ingrowth, and mineral deposition help researchers judge whether a design supports new bone formation. The resulting information can guide graft optimization, therapeutic-factor or cell delivery strategies, and future approaches to restoring structural continuity.
