  1. Ex vivo

    Ex vivo means that which takes place outside an organism. In science, ex vivo refers to experimentation or measurements done in or on tissue in an artificial environment outside the organism with the minimum alteration of natural conditions. Ex vivo conditions allow experimentation under more controlled conditions than is possible in in vivo experiments, at the expense of altering the "natural" environment. A primary advantage of using ex vivo tissues is the ability to perform tests or measurements that would otherwise not be possible or ethical in living subjects. Tissues may be removed in many ways, including in part, as whole organs, or as larger organ systems. Examples of ex vivo specimen use include: ⁕assays; ⁕measurements of physical, thermal, electrical, mechanical, optical and other tissue properties, especially in various environments that may not be life-sustaining; ⁕realistic models for surgical procedure development; ⁕investigations into the interaction of different energy types with tissues; ⁕or as phantoms in imaging technique development. The term ex vivo is often differentiated from the term in vitro in that the tissue or cells need not be in culture; these two terms are not synonymous.
