Whats the difference between ex vivo and in vivo gene therapy

Ex vivo gene therapy - this is carried out by removing the intended cell from the patient's body before administration of the gene therapy, after which the cell is returned.

In vivo gene therapy - this is carried out directly on the cell while its still on the patient's body.

Explanation:

Ex vivo, Latin for "out of the living" is a process that takes place outside an organism. Scientifically, ex vivo involves experiments that are conducted outside of a living body; the tissues or organs are taken out of the body, experimented on and returned.

In vivo which is Latin for "within the living" on the other hand is a process that take place outside an organism. Unlike ex vivo, it involves experiments that are conducted with or within a living body.

Gene therapy refers to a process that is carried out to alter the genetic make up of an individual with the intent of treating a disease.

In ex vivo gene therapy, the intended cells are removed from the patient's body and the gene therapy is applied to the cells before they are put back in the patient's body. But with in vivo gene therapy, the gene therapy is applied directly on the intended cells while its on the patient's body.
