Mouse models of multiple myeloma (MM) are basic tools for translational research and play a fundamental role
in the development of new therapeutics against plasma cell malignancies. All available models, including transplantable
murine tumors in syngenic mice, xenografts of established human cell lines in immunocompromised mice and transgenic
models that mirror specific steps of MM pathogenesis, have demonstrated some weaknesses in predicting clinical results,
particularly for new drugs targeting the human bone marrow microenvironment (huBMM). The recent interest to models
recapitulating the in vivo growth of primary MM cells in a human (SCID-hu) or humanized (SCID-synth-hu) host
recipient has provided powerful platforms for the investigation of new compounds targeting MM and/or its huBMM.
Here, we review and discuss strengths and weaknesses of the key in vivo models that are currently utilized in the MM
