Federal authority strictly regulates stem cell research:

• Federal Policy on Stem Cell Research
• Guidance for Investigators and IRBs Regarding Research Involving Human Embryonic Stem Cells, Germ Cells and Stem Cell-Derived Test Articles

The National Institutes of Health (NIH) have established sites to guide researchers who conduct stem cell research:

• Novel Approaches to Enhance Animal Stem Cell Research
• NIH Human Embryonic Stem Cell Registry
• NIH Stem Cell Information
• NIH Research Ethics and Stem Cells
