Ex vivo

Ex vivo ( Latin for 'outside of the living') refers to processes or processes in which living biological material, in particular cells , tissue or organs , is removed from a living organism and usually cultivated outside of it for a limited period of time. This enables the material to be treated and examined under controlled conditions. Examples of ex vivo methods are ex vivo gene therapy , examinations on the Langendorff heart and the ex vivo eye irritation test (EVEIT).

For example, in ex vivo gene therapy, genes are introduced into cells that have been taken from an individual. The cells that have been modified in this way are then returned to the individual in order to treat a hereditary disease .
