This protocol provides a method to establish humanized mice (hu-NSG) via intrahepatic injection of human hematopoietic stem cells into radiation-conditioned neonatal NSG mice. The hu-NSG mouse is susceptible to HIV infection and combinatorial antiretroviral therapy (cART) and serves as a suitable pathophysiological model for HIV replication and latency investigations.

This video demonstrates an imaging-based method to visualize transplanted luciferase-expressing beta cells into a non-obese diabetic immunodeficient mouse. The introduction of splenocytes from a diabetic mouse leads to progressive beta cell destruction, visually confirmed by declining luminescence after substrate introduction.

This video demonstrates an assay to generate a humanized xenograft mouse model. An immunocompromised mouse is injected with cyclophosphamide to cause immune cell depletion. Patient-derived tumor cells mixed with human peripheral blood mononuclear cells (PBMCs) in a hydrogel are subcutaneously injected into the mouse, forming a tumor with infiltrating T cells.

A procedure for making en face preparations of the mouse carotid artery and aorta is described. Such preparations, when immunofluorescently stained with specific antibodies, enable us to study localization of proteins and identification of cell types within the entire vascular wall by confocal microscopy.
FAQs
The model combines loss of functional T and B lymphocytes with reduced innate immune activity associated with the NOD background. This limits several host defenses that could otherwise recognize or eliminate implanted human tumor cells. Consequently, preparation must preserve the animals’ health and maintain consistent environmental conditions, because successful engraftment depends on both immune compatibility and reliable experimental handling.
Because these mice have impaired immune protection, environmental exposure and routine handling can affect health, tumor establishment, and study consistency. Specialized housing, aseptic technique, and controlled procedures help limit avoidable variation during preparation. Standardizing these conditions makes differences in tumor growth or treatment response more likely to reflect the experimental intervention rather than uncontrolled effects of animal care.
Important preparation variables include animal selection, housing conditions, handling practices, conditioning procedures, and health monitoring. Keeping these factors consistent helps reduce variation in engraftment and subsequent tumor development. In cancer research, this standardization is especially important when comparing tumor growth or therapeutic responses across experimental groups, since preparation-related differences can influence outcomes before treatment begins.
Preparation begins with selecting appropriate animals, followed by placement in suitable specialized housing and use of careful handling practices. Researchers then apply the planned conditioning procedures while maintaining aseptic technique and monitoring animal health. Once preparation is complete, the animals can support tumor xenograft experiments designed to assess engraftment, tumor growth, or responses to therapy.
Aseptic technique helps protect animals whose impaired immune function reduces their ability to control environmental challenges. It is therefore an essential part of handling and housing rather than an optional refinement. Consistent aseptic practice supports animal welfare and helps prevent preparation-related complications from confounding measurements of tumor establishment, growth, or treatment response.
Researchers should monitor animal health and the outcomes relevant to the planned cancer experiment, including tumor engraftment and subsequent tumor growth. Careful observation helps identify whether variation arises from the preparation process or from the tumor or treatment being studied. Monitoring also supports animal welfare and strengthens the reproducibility of in vivo measurements.
Prepared animals can support in vivo studies of human tumor biology by allowing investigators to examine whether tumor cells establish, how tumors grow, and how they respond to therapeutic interventions. These observations connect cellular or molecular cancer questions with whole-animal outcomes. Consistent preparation is necessary for interpreting drug efficacy and distinguishing treatment effects from differences in engraftment or care.
