In vitro vs in vivo vs in silico models

Welcome to this lecture on in vitro versus in vivo versus in silico models, providing an overview of the three main models in preclinical and translational research, in vitro, in vivo, and in silico approaches, including their definitions and typical applications. We will discuss the strengths and limitations of each, such as efficiency and control in vitro, physiological relevance in Vivo, and the predictive power of in silico methods. The importance of choosing the right model for specific research questions and the challenges of translating findings to humans will also be examined. Finally, we'll emphasize how integrating these methods can drive more effective and reliable advances in medical science. We will explore the three main approaches to preclinical and translational research in vitro, in vivo, and in silico models. In vitro means in glass, referring to experiments done outside living organisms using cells, tissues, or biomolecules. In Vivo involves studies within living organisms, often animals, sometimes humans. In silico uses computational methods. These modalities represent different tiers of complexity, each addressing distinct aspects of research. In vitro models provide a control system for studying molecular interactions, enzyme kinetics, drug metabolism, and cell signaling. They are crucial for drug screening, mechanistic studies, and toxicity assessment. In Vivo models such as rodents
