Genetic manipulation can take place ex vivo or in vivo. In
ex vivo experiments and trials, cells are removed and cultured
before being manipulated and replaced. This approach is
feasible for therapies involving cells such as haemopoetic cells
and skin cells that can be easily cultured and transplanted. In
in vivo methods, the modifying agents are introduced directly
into the individual.
