NSG™ and NSG™-SGM3 Mice engrafted with human hematopoetic stem cells represent powerful tools for studying oncology, infectious disease, and hematopoiesis and are helping accelerate the development of novel therapies.
JAX works with you to design studies that
yield clinically relevant results.
Humanized-PBMC-NSG™ mice are widely used as models of human-to-mouse xenogeneic GvHD, as well as studying immune function in vivo. Peripheral blood mononuclear cells (PBMCs) engraft with high efficiency into NSG™ mice due to the lack of mature murine lymphocytes and natural killer cells. The high degree of immunodeficiency allows engraftment of larger cohorts from a single donor, creating a robust and reproducible study platform.
Standard study includes:
Shown in the figure below are sample control and vehicle arms of a standard five arm study. Survival (A) and body weight (B) data demonstrate efficacy of the immunosuppressive drug Enbrel® (etanercept) in this platform. Standard studies run for thirty-five days and include dosing up to three times weekly for five weeks. Assessments are performed three times per week. A quality control group is engrafted in parallel with study arms to confirm PBMC engraftment.
Sample data from preclinical GvHD study. A. Survival curve of saline-treated control (group 1) vs treatment with Enbrel® (etanercept, group 2). B. Mean body weight of untreated control group declines significantly more rapidly than treatment group (n = 20 or 12 per group).
