In vivo refers to experiments or studies that are conducted inside a living organism or cell, usually in a laboratory animal or human subject. The term “in vivo” is Latin for “in the living.”
In vivo studies can be conducted on a wide range of biological and medical systems, such as diseases, drug development, or physiological functions. In vivo studies can be used to investigate the mechanisms and effects of drugs, treatments, or environmental factors on living organisms, and to explore the molecular and physiological processes that underlie various biological functions.
In vivo studies are important because they can provide insights into the complex interactions between different biological systems and the effects of various factors on living organisms. In vivo studies can also be used to test the safety and efficacy of new drugs or treatments before they are used in humans.
However, in vivo studies also have limitations. Conducting in vivo studies can be more expensive and time-consuming than in vitro studies, and they can also be more difficult to control due to the complex biological and environmental factors involved. In vivo studies may also raise ethical concerns related to the use of animals or humans in research.
Overall, in vivo studies are an essential tool in biological and medical research, as they provide a more comprehensive understanding of the biological systems and processes that underlie human health and disease.
