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.

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.

In Vitro Mineralization Assay: A Colorimetric Method to Quantify Osteoblast Calcium Deposits on Bone Graft Substitute by Alizarin Red S Staining and Extraction
0 Views •
2025
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.

FAQs
Porous scaffolds support bone repair by creating an osteoconductive framework, meaning a surface and structure that can support cell attachment and tissue ingrowth. Their architecture helps new tissue occupy the defect, while the scaffold’s material properties influence how effectively this process occurs. This makes porosity a functional design feature rather than merely a physical characteristic.
Some biologic materials may contribute signals that promote osteogenic activity, supporting bone-forming processes at the repair site. This differs from a scaffold’s primarily structural contribution: one supplies signaling potential, while the other provides an environment for attachment and ingrowth. Considering both functions helps explain why alternatives can be designed around different mechanisms.
Gradual resorption can allow a temporary material to be replaced by new bone, rather than leaving the scaffold as the final structure. The desired balance depends on material properties and the defect environment: resorption must support the repair process while new tissue develops. This relationship links scaffold persistence with the timing of regeneration.
Bone graft alternatives become particularly relevant when an autograft or donor bone is unavailable, insufficient, or undesirable. They may expand treatment options while reducing donor-site complications associated with obtaining tissue from the patient. However, their suitability still depends on the defect, vascularization, material behavior, and the patient’s capacity for bone regeneration.
Performance depends on several interacting conditions, including the material’s properties, the size and characteristics of the defect, the availability of vascularization, and the patient’s capacity for bone regeneration. These factors affect cell attachment, tissue ingrowth, signaling, and replacement by new bone, so the same alternative may not perform identically in every clinical setting.
Bone graft alternatives are applied across several areas of medicine, including fracture healing, spinal fusion, dental reconstruction, and orthopedic implant procedures. These settings may require structural support, biologic stimulation, or gradual replacement by new bone. Their broad use reflects the need for options when conventional autograft or donor bone cannot meet clinical requirements.
Evaluation can focus on whether the material supports cell attachment, tissue ingrowth, osteogenic activity, and eventual replacement by new bone. Clinicians must also consider the condition of the defect, vascularization, and the patient’s regenerative capacity. Together, these outcomes indicate whether the alternative is providing appropriate support for the intended repair or reconstruction.
