JAX™ NSG® Mouse Variant Portfolio

NSG® mouse model variants are the most highly immunodeficient mice and the models of choice for cancer xenograft modelling, stem cell biology, humanised mice, and infectious disease research. Charles River is the exclusive distributor of JAX™ Mice in Europe.

Lymphoma Incidence Low Low Low
Benefits • Engrafts the widest range of solid and hematological cancers, including ALL and AML

• Most sensitive host for cancer stem cells when compared to NOD SCID or nude mice

• Longer lifespan than NOD SCID; supports long-term engraftment studies and capabilities; >89 weeks median
•  Increased CD4+ FoxP3+ regulatory T cell population after CD34+ humanization

• Enhances human myelopoiesis and terminal differentiation after CD34+ humanization

• Increased efficiency of engrafting human acute myeloid leukemia (AML)
•  Long-term multilineage hematopoeitic stem cell repopulation similar to NSG mice

• Engrafts human PBMC without irradiation similar to NSG

• Engrafts a wide range if solid and hematological cancers
Considerations •  No thymic lymphomas, can be used for long & short-term experiments

•  Sensitive to irradiation
•  Compromised human stem cell regeneration

•  Suppression of human erythropoiesis

•  Reduction of human B-lymphopoiesis
• No thymic lymphomas, can be used for long & short-term experiments

•  Requires higher dose of irradiation to obtain human HSC engraftment

Benefits •  High engraftment of HLA-A2-restricted immune cells after CD34+ humanization

•  Enable functional CD4+ T cell responses to viral infection after CD34+ humanization (014570)
•  Useful for transplantation studies in the absence of xeno-GVHD

•  Develop allo-GVHD post-engraftmentof DR4-negative CD4+ T cells (017637)
•  Resistant to xeno-GVHD (010636)

•  Attenuated xeno-GVHD development post-hPBMC transplantation (023848)

•  High hCD45+ cell engraftment (023848)

•  Useful for studying mechanisms for xeno-GVHD
Considerations •  No thymic lymphomas - can be used for long-term experiments

•  Sensitive to irradiation
•  Reduced CD45+ cell engraftment compared to NSG

•  Higher proportion of mice with no CD45+ cell engraftment as compared to NSG (017637)
•  Reduced survival post hCD34+ cell transplantation compared to NSG mice (023848)
