In vitro studies

Definition

In vitro studies refer to experiments conducted outside of a living organism, typically in controlled environments such as test tubes or petri dishes. This method allows researchers to examine biological processes, responses, and interactions at the cellular or molecular level without the complexities of whole organisms.
