Interlinked stem cell research procedures

The following research procedures are only permissible in association with other procedures, which is referred to here as "linkage".

The following section explains the concept of interlinked research procedures in stem cell research.

Derivation of human embryonic stem cells

Derivation of human embryonic stem cells from surplus embryos is only permissible with a view to conducting a specific stem cell research project. This means that the derivation of new stem cell lines is only possible in association with a subsequent project. The rationale for the legislative requirement of linkage is that human embryonic stem cells are to be derived, not for stockpiling, but only in cases where they are to be used for specific research projects.

Derivation is linked to a research project involving human embryonic stem cells. The linkage requirement does not apply to new stem cell lines derived in the course of a research project which is aimed at improving derivation methods (RP-DM). These projects are primarily designed to improve inefficient methods of derivation. In a project of this type, the derivation of stable new cell lines is not an essential aim. Research projects aimed at improving derivation methods are not linked to research projects involving human embryonic stem cells.

Import of human embryonic stem cells

The import of human embryonic stem cells is permissible exclusively with a view to conducting a specific stem cell research project. The import of human embryonic stem cells for stockpiling is prohibited. Imports are linked to research projects involving human embryonic stem cells.

Export of human embryonic stem cells

The export of human embryonic stem cells is only permitted if the cells are to be used for a specific stem cell research project abroad. Exports are linked to research projects involving human embryonic stem cells abroad.
