Patient-derived xenograft (PDX) models and transplantable genetically engineered mouse models faithfully recapitulate human disease and are preferred models for basic and translational breast cancer research. Here, a method is described to orthotopically transplant breast tumor fragments into the mammary fat pad to study tumor biology and evaluate drug response.

Activation of latent mutations with adenovirus-Cre into the mammary ductal system results in a clinically relevant metastatic breast cancer. Incorporation of a YFP promoter allows tracking of distal metastatic tumor cells. This model is useful to study latent metastasis, anti-tumor immunity, and for designing novel immunotherapies to treat breast cancer.

FAQs
Their tissue architecture keeps cancer cells together with stromal components and cell-matrix relationships. This arrangement preserves heterogeneity, meaning the different cell populations and characteristics present within the tumor, while maintaining a three-dimensional setting. As a result, researchers can examine tumor behavior in a context that more closely reflects the original tissue than isolated cell cultures.
Stromal components and the surrounding matrix provide biological context for studying communication within the tumor microenvironment. Their continued presence allows investigators to evaluate tumor behavior alongside interactions between cancer cells and nearby tissue elements. This is particularly relevant when examining growth, treatment response, or resistance mechanisms that may depend on relationships preserved inside the fragment.
Controlled experimental conditions are central to maintaining the properties that make the fragments informative. Researchers standardize fragment size and maintain the tissue under defined conditions so that its cellular and three-dimensional features remain available for analysis. Variation in preparation or maintenance could affect how consistently researchers assess tumor growth, treatment response, or microenvironmental communication.
The workflow begins with breast cancer tissue obtained from a surgical specimen. Researchers then divide the specimen into standardized pieces and maintain those pieces under controlled experimental conditions. The prepared fragments can subsequently be examined for tumor biology, growth, treatment response, resistance mechanisms, or interactions among cancer cells, stromal components, and the surrounding matrix.
Researchers may choose this approach when preserving tumor heterogeneity and three-dimensional organization is important to the question being asked. The fragments retain cancer cells together with stromal components and cell-matrix interactions, allowing studies of treatment response, resistance, and tumor-microenvironment communication. They therefore provide complementary information that isolated cell cultures can lose.
Because the starting material comes from a surgical tumor specimen and retains features of that tissue, findings from the fragments can be interpreted in a patient-linked biological context. Researchers can investigate how the preserved tumor organization relates to growth or treatment response, helping connect controlled laboratory experiments with characteristics of the individual disease rather than relying only on simplified culture systems.
