Abstract
In vitro studies are defined as studies of biologic processes made to occur outside the body in an artificial environment. This may involve cultivating cells, metabolic and/or kinetic studies, or recording electrical and mechanical activity. The clear advantage of having a piece of isolated tissue is that a series of naturally occurring humoral factors can be ruled out and a controlled situation obtained. However, the natural activity of the tissue may only be assumed to be present, as acute denervation and sudden disappearance of normal circulation are difficult factors to evaluate. It is well known that tissue which has been removed and placed in an artificial medium needs a certain time to recover or equilibrate to the new situation. Often, one medium is used for transportation and a second for the actual study of the functions.
