"in vitro" (Latin)

What does the Latin term in vitro mean?

"In vitro" is a Latin term used in scientific and medical contexts. It translates to "in glass" and refers to experiments, tests, or processes that are conducted outside of a living organism, typically in a controlled laboratory environment, such as a test tube or petri dish. When research or testing is performed "in vitro," it means that it is being carried out using isolated cells, tissues, or biological components outside of their natural biological system. This approach allows scientists to study specific biological processes, interactions, or responses under controlled conditions.
