The NIH Stem Cell Unit (SCU) has analyzed and compared the 21 human embryonic stem cell (hESC) lines approved under prior presidential policy, which was revoked March 9, 2009, by President Barack Obama's Executive Order 13505. As per the July 7, 2009, NIH stem cell guidelines, the eligibility of the use of these lines in NIH-supported research will be determined at a later date.
The NIH SCU has acquired the previously approved 21 available hESC lines listed from BresaGen, Inc.; ES Cell International; Technion-Israel Institute of Technology; the University of California, San Francisco; the Wisconsin Alumni Research Foundation (WiCell Research Institute); and Cellartis AB.
