Mouse models for cancer research

Tumor bearing Mouse DEN model PDX model CDX model

Shanghai Model Organisms Center provides multiple types of tumor-bearing mouse models for cancer research and drug efficacy testing, including cell line-derived xenograft model (CDX) and patient-derived xenograft model (PDX). While PDX models better reflect the heterogeneity and diversity of human cancers, CDX models allow researchers to advance their pre-clinical drug development in a cost- and time-efficient manner.

Liver Cancer PDX Model

PDX PDX models Patient-derived Xenografts

Patient-derived Xenografts (PDX) are advanced preclinical oncology models for drug development. It offers a far better alternative for preclinical drug evaluation as compared to the conventional cell line-derived xenograft model.

Inflammation Models

inflammation diseases inflammation research inflammatory factors

Inflammation is a common yet important pathological process. Any factor that may cause tissue damage can lead to inflammation. Anomal inflammatory response may result in chronic inflammation, autoimmune diseases and even cancer. The regulation of inflammation-related genes is an important topic in the study of the development of inflammation.

Evaluating the Efficacy of Tumor-targeted Antibody in vivo

immunotherapy immune checkpoint immune checkpoint genes

As the most frequently used animal model, mice have been widely applied in the evaluation of drug efficacy. However, the human immune checkpoint genes only share ~60% identity with their murine counterparts. Thus antibodies that recognize human proteins do not necessarily interact with murine proteins, making it inappropriate to use wild type mice for evaluating the in vivo efficacy of human-specific antibody. The humanized immune checkpoint mouse models (Immune-Hu models), which were independently developed by Shanghai Model Organisms Center, are ideal models to evaluate the efficacy of anti-tumor antibody therapy.

Why We Need Humanized Mice?

Osteoporosis

Tnfrsf11b (Opg) knockout mice were generated through homologous recombination and supplied by Shanghai Research Center for Model Organisms. This mouse model, which is referred to as the "osteoporotic mouse", shows a typical phenotype of osteoporosis and arterial calcification, and Therefore, this animal model is ideal for drug screening and evaluation for the treatment of "human osteoporosis", in gene therapy of osteoporosis, as well as in the research on the mechanisms of interaction between osteoclasts and osteoblasts.

Popular Model Organisms

genetically modified organisms transgenic organisms genetically modified organisms examples

Model organisms are instrumental to the study of gene functions. Gene editing technology has always played a crucial role in the research on gene functions, diseases and drug discovery, through its application in genetic engineering of model organisms, mimicking of human diseases, as well as observation of physiological or pathological changes. In particular, the CRISPR/Cas9 technology has achieved remarkable breakthroughs in recent years, significantly improving the efficiency of genetic engineering in model organisms, and facilitating more extensive and in-depth applications of animal models in various research fields.

Disease Mouse Models (Non-genetically-engineered)

Shanghai Model Organisms has established a library of typical mouse models of human diseases through surgery or drug induction, thereby providing useful animal models for the research on pathogenesis of related diseases, functional studies of genes or proteins in diseases, screening of disease drugs and evaluation of therapeutic effects, etc.
