Human Immune System Mice

HUMAN iMMUNE SYSTEM MICE

huPBMC-NCG

Type : PBMC Humanized Mice
Strain Number: T057056
Background Strain: NCG [T001475]

STRAIN DESCRIPTION

The huPBMC-NCG mouse model is established by transplanting Peripheral Blood Mononuclear Cells (PBMCs) from healthy donors into highly immunodeficient NCG mice to create a human immune system-reconstituted model. This model supports rapid immune cell engraftment, primarily consisting of T cells, making it suitable for preclinical evaluation of anti-tumor therapies. However, due to the fast expansion of human T cells, these cells can recognize and attack murine tissues, leading to graft-versus-host disease (GvHD) within 5–7 weeks post-injection. This feature also makes the model ideal for studying anti-GvHD therapeutics. To minimize variability caused by different PBMC donors, we have established a screened huPBMC donor library to ensure consistent immune reconstitution across experiments.

APPLICATIONS

Preclinical anti-tumor efficacy studies and safety evaluation

Short-term efficacy evaluation

Evaluation of anti-GvHD drugs

Human PBMCs were injected through the caudal vein (1×107cells) into NCG mice for huPBMC reconstitution. The proportion of human CD45+ leukocytes in the peripheral blood of huPBMC-NCG mice gradually increased over time, with the mean proportion of human leukocytes exceeding 50% by the third week, predominantly CD3+ T cells. Due for development of GvHD, huPBMC-NCG mice have a relatively short treatment period from Week-2 to week-5 post PBCM injection.

Features of HuHSC-NCG

1.Predominant with T-cells

2.Relatively short lifespan due to GvHD

  • GvHD can be avoided using NCG-MHC-dKO
