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.

Type of genetic engineering

genetic modified organism types of genetic engineering genetic engineering technology

Three types of genetic modification by the gene engineered technology: gene knockout. gene knock-in, gene overexpression.

Lineage tracing

lineage tracing genetic lineage tracing genetic fate mapping

Genetic lineage tracing is a commonly used and the most effective method for studying the origin and fate of specific cell types. The construction of genetically engineered mouse model is the most important step in the lineage tracing technique.

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.

Aging and Longevity Research

Humans have always been fascinated with the study of aging. Despite experiencing thousands of years of civilization, we have yet to clearly identify the mechanisms of aging. Either from the perspective of drug development or genetic research, the study of aging is undoubtedly a worthy cause.

U-GEMM Repository

The U-GEMM Repository has more than 6000 Genetically Engineered Mice & Rat Models, including KO , Flox，Cre/Dre, gene humanized knockin, Immunodeficiency, reporter Knockin , genetic disease and other models. You can Search for Mouse & Rat Models by Name, Catalog Number or Keyword.

Brca1 CKO Mouse Model

Our own-developed Brca1 conditional knockout mice (Brca1-CKO) can be used to study breast cancer.
