The video explains a stepwise surgical method for orthotopic implantation of a tumor fragment from a cancerous donor to the pancreas of a non-cancerous recipient mice for development of pancreatic cancer. Orthotopically implanted PDAC could recapture the tissue microenvironment of human pancreatic cancers than conventional subcutaneous (SC) models more accurately.

This video demonstrates a cell-based tumor vaccination assay. A mouse, intradermally injected with B16-F10 melanoma cells for tumor formation, is vaccinated with B16-F10 cells secreting Flt3L cytokine near the developed tumor. The secreted Flt3L from the vaccine promotes the maturation and proliferation of dendritic cells that then present tumor antigens to T cells in lymph nodes, triggering a targeted anti-tumor immune response.

FAQs
The organ-specific microenvironment contributes more than location alone: local stromal, vascular, and immune interactions can shape how an implanted tumor grows, invades surrounding tissue, and metastasizes. Preserving these relationships gives researchers a biological context for interpreting treatment responses and disease behavior, helping explain why findings may be more informative than results from tumors placed at distant sites.
A distant-site model does not preserve the same anatomical context as the organ where the corresponding cancer originates. Orthotopic placement maintains local interactions within that organ, which can support tumor behavior that more closely reflects human disease. This distinction is important when investigators interpret growth, invasion, metastasis, or responses to experimental interventions.
Interpretation depends on three linked choices: the tumor source, the anatomical implantation site, and the host model. These selections determine how closely the experimental system represents the disease being studied and which local stromal, vascular, or immune interactions are retained. Careful alignment of these elements improves the biological and translational value of the results.
The model can support analysis of tumor growth together with invasion and metastasis. Examining these outcomes in the relevant organ context allows investigators to assess disease behavior within local biological relationships rather than focusing only on expansion at an arbitrary site. This broader view is useful for studying how experimental interventions affect multiple features of tumor progression.
A study begins by selecting an appropriate tumor source, identifying the anatomical site corresponding to the cancer of interest, and choosing a suitable host model. Tumor cells or tissue are then placed in that site so the relevant organ environment is retained. The resulting model can be used to evaluate tumor behavior or planned therapeutic and diagnostic approaches.
Researchers may use this approach to evaluate anticancer drugs, immunotherapies, imaging approaches, or surgical strategies. Its value is that these interventions can be examined while the tumor develops within an organ-specific environment. The resulting observations may provide more biologically and translationally meaningful information than assessments performed after placement at a distant site.
In medicine, the system connects intervention testing with clinically relevant tumor behaviors, including growth, invasion, and metastasis. Investigators can therefore examine not only whether a strategy affects the implanted tumor, but also how outcomes relate to the surrounding organ context. This supports preclinical interpretation of drugs, immunotherapies, imaging methods, and surgical approaches.
