In jurisdictions crossing the spectrum of restrictive to liberal stem cell policies, banks and registries are emerging as an essential resource for transnational access to quality-controlled and ethically sourced stem cell lines.
The rationale for restrictive transfusion strategy stems from the recognition that exposure to allogeneic blood is associated with many potential complications, including infection, mis-transfusion, ABO-incompatibility, transfusion reaction, transfusion-related acute lung injury (TRALI), transfusion-associated circulatory overload (TACO), elevated risk of cancer, and more [36].

Some European Union member states have a restrictive approach on embryonic stem cell research because of religious, cultural and historical reasons [ 37].
Others established country-specific rules ranging from permissive, albeit highly regulated regimes, to restrictive laws forbidding the isolation of stem cells from human embryos under any circumstances[26].
Better than merely stemming the tide of restrictive laws, voters and election officials are now enjoying a positive wave of their own as more and more states move to expand voting access.
Other experts said Mr. Bush might also consider a more restrictive option: paying for research only on stem cell lines that have already been derived from human embryos.
This set the stage for a relatively restrictive environment for embryonic (although not adult) stem cell research in the United States relative to some other countries―the National Institutes of Health currently funds between about $600 miilion to $700 million a year in stem cell research.
Even Germany, with its restrictive policies toward hES cell work, devotes national funding to stem cell research; its priority, however, is work on adult stem cells.
