Glossaryin vitro

biological processes conducted outside a living organism

"In vitro" is a Latin term meaning "in glass." It refers to biological or chemical processes that are conducted outside of a living organism, typically in a controlled laboratory environment such as a petri dish or test tube. For example, in vitro studies might involve growing hair follicles in a lab to study alopecia treatments, allowing researchers to observe cellular behaviors and test interventions without the complexity of a whole living system.
