Patient-derived tumor xenograft mouse models have become the preferred animal model for translational cancer research and preclinical studies. Given the unmet need for improved predictive models in immuno-oncology, humanized mouse models which are co-engrafted with both human tumors and immune system components have been used to investigate ...

Patient-derived tumor xenograft (PDX) models in immune-deficient mice have been most frequently used for non-IO preclinical studies 11 to investigate drug efficacy, predictive biomarkers, and drug-resistant mechanisms.12 This review summarizes the state of science in humanized PDX models with a focus on their utility in lung cancer IO research.

Since immunodeficient murine hosts lack functional adaptive immunity, tumor–immune interactions cannot be faithfully studied. Humanized xenograft models overcome this limitation by engrafting mice with components of the human immune system, thereby creating a chimeric platform that supports both human tumor growth and immune response evaluation.

Explore GemPharmatech's extensive collection of immunodeficient mice models, including NCG and next-generation NCG strains. Our models are ideal for cancer immunotherapy research, cell-derived xenografts (CDX), patient-derived xenografts (PDX), and immune system reconstitution studies.

Humanized mice, encompassing human tumors and human immune cells engrafted on immunodeficient mice, have been widely used for many years in immuno-oncology, with developments to improve both the humanization and the translational value central to the next generation of models.

Immunodeficient mice and rats are used as hosts for xenografts and for immune system humanization. Taconic offers numerous strains from nudes to super immunodeficients using human cell lines, patient-derived xenografts, and humanized immune system models for immuno-oncology studies.

Immunodeficient mouse models are invaluable tools for preclinical research, particularly for cancer therapies and studies of the human immune system. Notably, strains with combined Prkdc (scid) and Il2rg (null) mutations—such as NOG and NSG mice— are widely used due to their profound immunodeficiency, allowing efficient engraftment of various human cells. However, these models were ...

In this review, we provide an overview of next-generation humanized mouse models suitable for the establishment and study of patient-derived tumors. Furthermore, we discuss the opportunities and challenges of modeling the tumor immune microenvironment and testing a variety of immunotherapeutic approaches using human immune system mouse models.

The patient-derived xenograft (PDX) model, which is the transplantation of human cancer tissues into humanized mice, is a popular system to reconstruct the environment of cancer patients (

Patient-derived xenograft (PDX) models, in which tumor tissues from patients are implanted into immunocompromised or humanized mice, have shown superiority in recapitulating the characteristics of ...
