What does NSG stand for in mice?
NOD scid gamma mouse
The NSG mouse (NOD scid gamma mouse) is a brand of immunodeficient laboratory mice, developed and marketed by Jackson Laboratory, which carries the strain NOD.
Are NSG mice humanized?
Humanized NSG™ (hu-NSG™) mouse models are powerful tools for studying cancer, inflammatory and infectious disease, and hematopoiesis. We maintain large on-the-shelf inventories of two versatile humanized models.
Why NSG mice are irradiated?
Why do NSG™ mice require irradiation before hematopoietic stem cell engraftment? Treatment with radiation (usually from an X-irradiator or a cesium source) is a prerequisite for efficient colonization of mouse bone marrow by human hematopoietic stem cells.
What is the difference between Nog and NSG mice?
Thus, there is a difference in the Il2rg mutation between NOG and NSG mice. In NOG mice the Il2rg mutation produces a protein that is expressed and will bind cytokines but cannot signal, while the mutation in NSG mice is a complete null so that no Il2rg is expressed and cytokines cannot bind [16].
Do NSG mice have complement?
NSG mice lack hemolytic complement due to a 2-bp deletion in the coding region of. The absence of a functional membrane attack complex prevents monoclonal antibody-mediated complement-dependent cytotoxicity, which is important for mediating antitumor activity.

Do SCID mice have microglia?
Despite absence of neuropathology and lack of microglial activation, microglial numerical density was significantly increased in SCID mice.
Are NSG mice CD45 1 or CD45 2?
Because leukocytes derived from NSG and donor mice differ in their CD45 allele (recipients express CD45. 1, donors express CD45. 2), cell origins can be readily distinguished by cell-surface staining.
Do NSG mice have lymph nodes?
The NSG mice have only small, residual lymph nodes, but the tumor cells still metastasized to these residual lymph nodes and formed large, palpable tumors in the axillary and brachial lymph nodes. Remarkably, even metastases to the brain and bones formed following injection at the orthotopic site.
Do NSG mice have spleens?
In this study, we characterized the immunophenotype of spontaneous lymphoma/leukemia in 12 NSG mice (20 to 38 weeks old). The mice had a combination of grossly enlarged thymus, spleen, or lymph nodes and variable histologic involvement of the bone marrow and other tissues.
Are NOD mice immunodeficient?
It turns out that NOD inbred mice have inherent deficiencies in key humoral and cellular immune cell activities that enhances the overall immune deficiency of NOD-scid mice in comparison to C.B-17-scid or C57BL/6-scid (B6. CB17-Prkdcscid/SzJ) –mice.
