Animal models of multiple myeloma and their utility in drug discovery

Area of Science:

• Oncology
• Preclinical Research
• Animal Models

Background:

• Developing effective multiple myeloma (MM) therapies necessitates reproducible and biologically relevant in vivo models.
• Current preclinical models are crucial for evaluating novel treatments and optimizing their clinical application.

Purpose of the Study:

• To present protocols for establishing and maintaining human extramedullary multiple myeloma (MM) tumors in mice.
• To demonstrate the utility of these models for evaluating novel anti-MM agents and therapeutic strategies.

Main Methods:

• Protocols for generating and maintaining human extramedullary MM tumors in mice.
• Techniques for excising tumors, creating single-cell suspensions, and injecting MM cells via subcutaneous, intravenous, or intratibial routes.
• Utilizing established tumors for preclinical drug evaluation.

Main Results:

• Successfully generated and maintained human extramedullary MM tumors in mice.
• Demonstrated the feasibility of using these xenograft models to assess therapeutic efficacy.
• Established a versatile platform for preclinical evaluation of anti-MM agents.

Conclusions:

• The developed in vivo models provide a reproducible and biologically relevant platform for multiple myeloma research.
• These models facilitate the evaluation of novel therapies, including drug combinations and optimized dosing, for accelerated clinical translation.
• This methodology supports the advancement of new treatments for multiple myeloma patients.
