In Vitro Techniques refer to methods that study biological processes outside of a living organism, typically in a controlled laboratory environment. These techniques often involve the use of cells, tissues, or organs cultured in petri dishes or test tubes, allowing researchers to observe cellular behavior, drug interactions, and disease mechanisms without the complexities of a whole organism. Common applications of In Vitro Techniques include drug testing, toxicity assessments, and genetic studies. By isolating specific biological components, scientists can gain insights into cellular functions and develop new therapies, making these techniques essential in fields like pharmacology and molecular biology.
