The protocol describes a new method to disaggregate human tissues and to create autologous micro-grafts that, combined with collagen sponges, give rise to human bio-complexes ready to use in the treatment of skin lesions. Further, this system preserves cell viability of micro-grafts at different times after mechanical disaggregation.

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.

Culturing human Mesenchymal Stromal Cells (hMSCs) with autologous serum, reduces the risks of rejection by xenogeneic material and other negative effects. It also allows for the recovery of a subset of mesodermal progenitors, which can deliver fresh hMSCs. Embedding hMSCs in an autologous fibrin clot enables easy handling and effective surgical implantation.
FAQs
The graft supports healing through several complementary components. Living bone cells contribute directly to osteogenesis, meaning new bone formation, while the mineralized matrix provides structural support. Signaling factors promote osteoinduction, the stimulation of bone-forming activity. Together, these properties help the graft integrate with surrounding tissue rather than serving only as a passive structural filler.
These processes address different requirements of skeletal repair. Osteogenesis supplies bone-forming activity, osteoinduction encourages that activity through signaling factors, and integration connects the graft with surrounding tissue. Their combination can support a more biologically active repair while also maintaining structural stability, which is particularly relevant when surgeons are treating defects, bone loss, or reconstruction needs.
Because the transferred tissue comes from the same patient, it avoids the allogeneic immune response associated with tissue from another individual. This compatibility allows the graft’s living cells, mineralized matrix, and signaling factors to participate in repair without introducing a donor-recipient mismatch. The result is a biologically compatible option for supporting skeletal healing and reconstruction.
Clinical uses include fracture repair, spinal fusion, dental reconstruction, maxillofacial reconstruction, and treatment of bone loss. These applications differ in anatomical setting, but each may require both structural support and biological participation in healing. The technique is therefore relevant across orthopedic, spinal, dental, and maxillofacial procedures when restoration or union of bone is needed.
The procedure requires identifying a suitable harvest site in the same patient, obtaining the bone, and transferring it to the area requiring repair or reconstruction. Harvesting creates an additional surgical site, so the overall procedure includes more than management of the original defect. This tradeoff must be considered alongside the graft’s structural and biological advantages.
Its continuing importance reflects the combination of reliable structural support, living bone cells, mineralized matrix, signaling factors, and compatibility with the recipient. These features can promote osteogenesis, osteoinduction, and integration with surrounding tissue. Although harvesting adds a second surgical site, the potential for dependable union keeps this approach central to fracture repair and skeletal reconstruction.
