Animal Models of Multiple Myeloma

Area of Science:

• Oncology
• Hematology
• Preclinical Research

Background:

• Multiple myeloma (MM) is a plasma cell neoplasm characterized by interactions with the bone marrow microenvironment.
• Understanding these interactions requires in vivo models that mimic MM growth conditions.
• Selecting the appropriate model system is critical for accurate MM research.

Purpose of the Study:

• To describe available murine models for multiple myeloma research.
• To detail methods for MM cell inoculation in mice (intravenous, intratibial, subcutaneous).
• To outline disease monitoring and organ processing techniques.

Main Methods:

• Inoculation of mice with multiple myeloma cells via intravenous, intratibial, or subcutaneous routes.
• Monitoring of disease progression and associated symptoms.
• Organ processing for subsequent analysis, including techniques for calcified tissue research.

Main Results:

• Established protocols for establishing and monitoring murine models of multiple myeloma.
• Demonstrated methods for assessing MM cell engraftment and dissemination.
• Highlighted the utility of microCT, histomorphometry, and biomechanical testing for evaluating MM-induced bone pathology.

Conclusions:

• Murine models are indispensable for recapitulating the complex in vivo environment of multiple myeloma.
• Standardized methods for inoculation, monitoring, and analysis enhance the reliability of MM research.
• Advanced imaging and testing techniques are crucial for studying MM's impact on bone.
