Why We Should Use Transgenic Mice for Scientific Research


For decades, transgenic mice have been used in scientific research to study human genetic diseases. Today, with the development of new techniques and technologies, transgenic mice are more popular than ever.

Introduction to transgenic mice

Transgenic mice are used in scientific research when it is necessary to remove or add a certain gene. Transgenic mice have a foreign gene inserted into their DNA that is not found in the natural mouse genome. This type of mouse is created by combining embryonic cells from an embryo with foreign DNA, which may come from other animals. The cells are then injected into the embryo, which will develop into an animal with the new DNA. Scientists use transgenic mice to study many things such as cancer, diabetes or arthritis.

Why they are used

Scientists use transgenic mice for scientific research because they are inexpensive, easy to maintain and well characterized. The first advantage is that they are inexpensive. Scientists can buy a mouse commercially or order a custom one from a breeder for a few hundred dollars. They don’t have to pay expenses like cages and food that would cost thousands of dollars. The second advantage is that they are easy to care for. The mice are small and take up little space in the lab, which makes it easier to keep them indoors and move them around if necessary.

Benefits of using them in scientific research

Mice are used in scientific research to study certain diseases. Transgenic mice have the advantage of being cheaper and more accessible than other animals commonly used to study diseases. Mice also reproduce more quickly.

Researchers can use the information they gather about transgenic mice to draw conclusions about human diseases. For example, one study found that a specific gene in mice is linked to obesity in humans. This link is important because it may help scientists identify new treatments for obesity and metabolic diseases.
