Spontaneously complicated requirements research Some embryonic stem cells

Despite the restrictions on federal funding for human embryonic research stem cells are up in the Obama administration, some researchers are finding new ethical requirements burdensome, Washington Post reports.

Under the administration of George W. Bush, only 21 stem cell "lines" was allowed to receive funding federal research. President Obama relaxed the restrictions, but allowed the National Institutes of Health to issue ethical guidelines. The guidelines, in part, requires that the stem cell research with federal funds meet certain ethical criteria, such as ensuring that people who donated the embryos were informed of other options.

Researchers have existing federal subsidies can continue studying the "Bush" lines, but any research involving the new concessions, not even research along the lines of age, must meet the guidelines of the NIH.

is not clear how many of the 21 lines within the guidelines of ethics. According to the Post, the NIH has approved 43 lines, only one of which is the original group of 21 lines. In addition, the NIH still has 115 lines of review, and only two of them are "Bush" lines.

Timothy Kamp, director of the center of and medicine stem cells regeneration at the University of Wisconsin, said: "Some of these lines were obtained over a decade ago," which means that the relevant records may not be available, and may not have records available, while "Some of the researchers derived lines no longer occur" or "could not be motivated to provide the records in a timely manner."

He added: "We are losing access to the lines of this approval process for a period of time - perhaps indefinitely. They are the main workhorses for many of our projects. " Kamp, said that the NIH should review its guidelines for the grandfather of the existing lines to give researchers a period of two years of grace so they can continue their research with new grants.

Lana Skirboll, director of NIH science policy, said the agency is "nice" but added, "Our responsibility is to ensure that we are conducting research lines of responsibility that comes "
