The survey results provide empirical data to support previously anecdotal concerns that delays in acquiring or an inability to acquire certain human embryonic stem cell lines may be hindering stem cell science in the United States," said Aaron Levine, an assistant professor in the School of Public Policy in the Ivan Allen College of Liberal Arts at the Georgia Institute of Technology.
19 August 2011 - US-based biotechnology company BioTime Inc (AMEX:BTX) announced today that four human embryonic stem (hES) cell lines: ESI-035, ESI-049, ESI-051 and ESI-053, developed by a BioTime subsidiary have been approved by the National Institutes of Health (NIH) for inclusion in the NIH Human Embryonic Stem Cell Registry.
Lamberth agreed and deemed human embryonic stem cell research illegal under the Dickey-Wicker Amendment, an annual feature in NIH's appropriations bill that prohibits the use of federal funds for research that destroys an embryo.
We believe the NIH's human embryonic stem cell research policies are sound, ethical, and responsible," said Elizabeth Blackburn, PhD, Nobel laureate and president of the AACR.
In fact, the NAS guidelines preclude only three research activities involving either human embryos or human embryonic stem cells: (1) the research use of human embryos beyond fourteen days (or the appearance of the primitive streak, if that comes first); (2) the creation of embryonic chimeras involving the transfer of human embryonic stem cells into nonhuman primate blastocysts or the transfer of any embryonic stem cells into human blastocysts; and (3) the breeding of any chimeras into which human embryonic stem cells have been transferred at any stage of development.
Before human therapy can be attempted, scientists need to learn how to entice human embryonic stem cells to become dopamine neurons.
Blackburn has written: "At council meetings, I consistently sensed resistance to presenting human embryonic stem cell research in a way that would acknowledge the scientific, experimentally verified realities.
The lack of sustained explorations of alternatives might be explained by the volume's focus on human embryonic stem cell research.
Geron and WARF have further agreed to grant research rights to existing human embryonic stem cell patents and patent filings to academic and governmental researchers without royalties or fees.
He claims that human embryonic stem cell research is "illegal, immoral and unnecessary.
After Geron scientists announced in November 1998 that they'd isolated human embryonic stem cells from donated embryos and aborted fetuses, President Clinton asked the National Bioethics Advisory Commission to look into any ethical issues associated with stem cells.
