EXV

Exv is a term used as an abbreviation or code across different domains. There is no single, universally accepted definition, and its meaning depends on the context.

In science, exv most commonly stands for ex vivo, a Latin phrase meaning "out of the living body." In biology and medicine, ex vivo describes experiments, analyses, or culture systems that use tissues, cells, or organs removed from an organism but studied outside the body. This usage contrasts with in vivo experiments conducted inside a living organism and in vitro experiments performed outside a biological context, often in artificial environments such as petri dishes or culture vessels. Ex vivo methods are valued for enabling controlled study while maintaining some native tissue characteristics, allowing functional analyses or drug testing on real tissues without whole-organism involvement.

Beyond scientific contexts, exv can appear as an acronym, code, or model designation in various organizations or datasets. These uses are nonstandard and highly context-dependent; to determine the intended meaning, one should consult the relevant source or documentation. In practice, when encountering exv, the surrounding material should guide interpretation, with ex vivo as the most common and widely recognized sense in scientific writing.
