NSG Mouse

The NSG mouse is a type of laboratory mouse that is commonly used in biomedical research. This mouse strain is characterized by its severe combined immunodeficiency, which makes it an ideal model for studying human diseases and testing potential treatments.

History

The NSG mouse was first developed in the late 20th century as a tool for studying the human immune system. The strain was created by crossing two existing strains of mice, the NOD/ShiLtJ mouse and the SCID mouse, to produce a mouse with a severely compromised immune system.

Characteristics

The NSG mouse is characterized by its lack of a functional immune system. This is due to a mutation in the Prkdc gene, which is responsible for DNA repair in immune cells. As a result, these mice are unable to produce functional B and T cells, which are crucial components of the immune system.

In addition to their immunodeficiency, NSG mice also have a number of other characteristics that make them useful for research. For example, they are highly susceptible to human cell engraftment, which allows researchers to introduce human cells into the mice and study their behavior in a living organism.

Uses in Research

Due to their unique characteristics, NSG mice are used in a wide range of research areas. These include cancer research, where they are used to study the growth and spread of human tumors, and immunology research, where they are used to study the human immune system.

In addition, NSG mice are also used in stem cell research, where they are used to study the behavior of human stem cells in a living organism. This has led to important advances in our understanding of stem cell biology and the development of new treatments for a range of diseases.
