Orders by weight:
- Super immunodeficient NOG mouse expressing human GM-CSF and human IL-3 cytokines to support myeloid lineage engraftment
- Higher overall engraftment levels of human hematopoietic stem cells (HSC) compared to core NOG mouse
- Higher levels of myeloid cell differentiation following human HSC engraftment compared to core NOG mouse
- Model of human allergy response
- Applications in research involving cancer, infectious disease, immunology, regenerative medicine and humanization
Taconic cannot accept orders by weight for this model. Please note that shipments may contain animals with a larger weight variation.
Origin: hGM-CSF/hIL3 NOG mice engrafted with human CD34+ hematopoietic stem cells (HSCs) stably develop extensive cell lineages as early as 6 to 8weeks post-injection. Both myeloid and lymphoid lineage cells are present in peripheral blood, bone marrow, thymus and spleen and non-lymphoid tissue including lung and liver. Longer term studies are possible in huNOG-EXL mice, with literature reports of stable engraftment and hematopoiesis for at least 20 weeks post engraftment. While, not all human immune cell types have been exhaustively characterized in these mice, extensive myeloid differentiation including granulocyte differentiation (basophil, neutrophil and mast cells) are evident in blood and tissues. Antigen presenting cells (dendritic cells and macrophages) are also increased in frequency, both in blood and spleen.
Availability: Taconic maintains an inventory of female huNOG-EXL mice engrafted as juveniles and FACS tested at 10 weeks post-engraftment; in order to ship, all mice must be ≥25% hCD45+ in peripheral blood, but in most cases huNOG-EXL mice average> 40% human cells in blood. Custom options for huNOG-EXL generation are available, such as HLA selection and time of QC and delivery post-engraftment with additional fee.
