Encapsulation of heterologous cells allows the production of therapeutic substances selectively in the required tissues of the patient. Thus high local concentrations help to minimise side effects in other parts of the body. Nevertheless, most substances show small therapeutic windows also at their site of action. Furthermore, the timing of the release has to be adjusted to the requirements of the patient and the treatment. Regulation from the outside is therefore necessary to adjust the expression in the transplanted cells.
