Osteoporosis

osteoporosis gene osteoporosis diseases Tnfrsf11b

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.

Gene Knock-in

gene knock in knock in mice knock in mouse

Knock-in represents the introduction of specific mutations or exogenous genes, such as point mutations (mimicking human genetic disease) at the selected location or reporter genes (e.g., EGFP, RFP, mCherry, YFP, LacZ, Luciferase etc.) or functional cDNAs (such as Cre, Dre etc.) into a specific genomic locus through homologous recombination, thereby allowing the exogenous DNA fragment to be expressed. A simultaneous occurrence of knock-in and knock-out can be achieved by replacing a murine endogenous gene with a foreign DNA fragment.

Gene overexpression

gene overexpression gene overexpression protocol gene overexpression techniques

Generate a mouse model in which an exogenous gene is introduced and overexpressed. An overexpression model can be used to investigate gene functions, promoter functions, or model the pathogenesis of human disease. Depending on the method to introduce foreign DNA, a random transgenes or targeted conditional overexpression model can be created.

GEMM-Derived Allografts

Who We are

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.

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.

Cancer Model

research on cancer cancer model mouse models of cancer

The laboratory mouse is widely considered as a valid and affordable model organism for studying human disease. Mouse models of cancer not only enable researchers to understand the genetic basis of tumor development in complicated and dynamic physiological systems, but also serve as irreplaceable tools for developing and testing new therapies.  Shanghai Model Organisms Center offers a variety of mouse models of cancer to meet the needs of both academic and industry partners.
