National Academies Guidelines for Human Embryonic Stem Cell Research
In 2005, the United States National Academies established the Guidelines for Human Embryonic Stem Cell Research. These standards were designed to ensure the integrity of research involving human embryonic stem cells (hESCs) and to promote responsible scientific practices. To ensure these standards remain current, the National Academies appointed the Human Embryonic Stem Cell Research Advisory Committee to provide ongoing updates.
The framework is built upon two foundational principles: the belief that hESC research can significantly advance our understanding of human health and lead to new medical treatments, and the requirement that embryos be donated freely through voluntary and informed consent. These guidelines implement executive order 13505 and specifically apply to research receiving funding from the National Institutes of Health (NIH).

Key Facts
- Purpose: To enhance the integrity and public perception of hESC research through responsible conduct.
- Funding Scope: Applies specifically to hESC research funded by the NIH.
- Core Requirement: Donors must provide voluntary, written, and informed consent.
- Source Limitation: Eligible embryos must have been created for reproductive purposes via in vitro fertilization (IVF) and no longer be needed for that purpose.
- Prohibitions: NIH funding is prohibited for the derivation of stem cells from human embryos and for research introducing hESCs into non-human primate blastocysts.
Eligibility for NIH Funding
To receive NIH funding, researchers must adhere to a strict set of regulations. Applicants may utilize stem cell lines already listed on the NIH registry or submit a formal assurance of compliance with the guidelines' specific requirements for cells derived from human embryos.
Requirements for Embryo Derivation
For a stem cell line to be eligible under the guidelines, the following criteria must be met:
- The hESCs must originate from embryos created through in vitro fertilization (IVF) for reproductive purposes that are no longer required for that intent.
- Donors must provide written consent for the embryos to be used in research.
- Complete documentation of the consent process must be provided.
Protections for Donors
The guidelines mandate strict safeguards to protect the identity and autonomy of donors. Healthcare facilities must explain all available options regarding the embryos to the patient. Crucially, no payments may be offered for donated embryos, and the decision to donate (or refuse to donate) must not affect the quality of medical care the patient receives.
To prevent conflicts of interest, a clear distinction is maintained between the decision to create embryos for reproduction and the decision to donate them for research. The decision to create embryos must be made without influence from researchers. Furthermore, donors retain the right to withdraw their consent at any time until the stem cells are derived or until the donor's identity can no longer be linked to the embryo.
The Informed Consent Process
Transparency is central to the donation process. Donors must be explicitly informed of several key points before consenting:
- The embryos will be used to derive stem cells for research purposes.
- The specific procedures involved in the derivation process.
- The possibility that derived stem cell lines may be maintained for many years.
- The donation is not directed toward a specific use, and the research is not intended to provide direct medical benefit to the donor.
- There may be commercial potential resulting from the research, but the donor will not benefit financially from such developments.
- Whether any information that could disclose their identity will be available to researchers.
Handling Pre-existing Stem Cell Lines
Researchers wishing to use stem cell lines established before the guidelines took effect have three paths to eligibility: using lines on the NIH registry, proving compliance with current requirements, or submitting materials to a working group of the Advisory Committee to the Director.
The working group reviews the submitted materials to verify that the cells were derived from embryos created for reproductive purposes that were no longer needed and that voluntary written consent was obtained. The working group then makes recommendations to the Advisory Committee, which advises the NIH director, who makes the final funding decision.
Funding Restrictions and Prohibitions
Certain types of research are strictly ineligible for NIH funding. This includes research where hESCs are introduced into non-human primate blastocysts (early-stage embryos) or the breeding of animals where hESCs might contribute to the germ line (reproductive cells). Additionally, due to annual appropriations bans, the NIH is prohibited from funding the actual derivation of stem cells from human embryos.
| Category | Eligible | Ineligible |
|---|---|---|
| Embryo Source | IVF embryos no longer needed for reproduction | Embryos created specifically for research |
| Consent | Voluntary, written, informed consent | Paid donations or coerced consent |
| Research Type | Standard hESC research (via registry/compliance) | Introduction into non-human primate blastocysts |
| Funding Activity | Research using existing eligible lines | The actual derivation of cells from embryos |
Frequently Asked Questions
Can donors be paid for donating embryos for stem cell research?
No. The guidelines explicitly state that no payments of any kind may be offered to individuals for the donation of embryos.
What happens if a donor changes their mind after donating?
Donors have the right to withdraw their consent at any time, provided the stem cells have not yet been derived from the embryo or the donor's identity can no longer be linked to the embryo.
Does the NIH fund the creation of stem cells from embryos?
No. The derivation of stem cells from human embryos is prohibited by the annual appropriations ban on funding human embryo research.
Are researchers allowed to use stem cell lines created before 2005?
Yes, provided the lines are on the NIH registry, the researcher can prove they meet current compliance standards, or the NIH director approves them following a review by the Advisory Committee's working group.
Will donors benefit financially if the research leads to a commercial product?
No. Donors must be informed that they will not benefit from any commercial development resulting from the research performed with their donation.
