Imaging tumor cell movement in vivo.

Area of Science:

• Oncology
• Metastasis Research
• Animal Models

Background:

• Rodent models are crucial for studying human cancer metastasis.
• Transgenic rodent lines and xenografts in immunocompromised mice are common models.
• Understanding tumor cell motility is key to metastasis research.

Purpose of the Study:

• To describe methods for analyzing tumor cell motility in mouse and rat models of breast cancer metastasis.
• To provide protocols for generating and imaging mammary tumors.
• To include methods for analyzing associated biological processes like macrophage and blood vessel dynamics.

Main Methods:

• Generation of mammary tumors in rodent models (mice and rats).
• In vivo imaging of tumor development and metastasis.
• Protocols for labeling macrophages and imaging blood vessels.
• Image analysis techniques for quantitative assessment.

Main Results:

• Established protocols for analyzing tumor cell motility in preclinical breast cancer models.
• Demonstrated the utility of rodent models for studying metastasis.
• Provided a comprehensive set of methods for comprehensive tumor analysis.

Conclusions:

• The described methods facilitate the study of breast cancer metastasis in well-established animal models.
• These techniques aid in understanding the complex processes of tumor cell motility and dissemination.
• The protocols support research into therapeutic strategies targeting metastasis.
