in Vitro ? in Vivo Development

In vitro and in vivo development are two terms used to distinguish between studies that take place in a laboratory setting (in vitro) and in living organisms (in vivo). In vitro development studies focus on the effects of individual cells or molecules in test tubes, Petri dishes, or other artificial environments. In contrast, in vivo studies examine the effects of whole organisms in their natural environments, such as the effects of a drug in a living organism. Both approaches are important for understanding the mechanisms of biological processes and diseases. In vitro and in vivo studies are used in biomedical research to better understand the development and function of cells, organs, and organisms. Inventions such as vaccines, gene therapy, and the manipulation of the microbiome have emerged from research in these two domains.
