GlossaryIn Vitro Models (in vitro systems)

experimental systems studying biological processes outside living organisms

These models often involve the use of cell cultures or tissue samples to investigate cellular behaviors, drug responses, or disease mechanisms, providing valuable insights without the ethical and practical complexities of in vivo (within a living organism) studies.
