Immunocompetent mouse models of multiple myeloma.

Abstract

Immunocompetent murine models of multiple myeloma are critical for understanding the pathogenesis of multiple myeloma and for the development of novel immunotherapeutics. Different models are available in Balb/c and C57Bl strains, each with different advantages and disadvantages. The availability of many transplantable cell lines allows for the conduct of experiments with large cohorts of mice bearing identical tumors, while cell lines that grow in vitro can be used for genetic manipulations. The introduction of human CRBN into these models allows for the study of IMiDs and cereblon based PROTACs in mice. New genetically engineered models based on germinal center cell activation of Nsd2 or Ccnd1 together with constitutive NFkB are being developed to model some of the important genetic subtypes of human multiple myeloma.
