The National Institutes of Health (NIH) has approved 13 new stem cell lines for use in agency-funded research.
The move follows a March 2009 order by President Obama that expanded the NIH's ability to fund stem cell research. Previously, an order by President Bush in 2001 had limited federal funding of stem cell research to studies of 60 existing lines of cells.
The new lines were approved based on the NIH Guidelines for Human Stem Cell Research adopted in July 2009 (http://stemcells.nih.gov/policy/2009guidelines.htm). These guidelines require that stem cell lines used in federal research be derived from embryos donated by individuals who gave informed consent. The NIH is considering whether to approve an additional 96 cell lines.
