WiCell - an private not-for-profit - is working to fill the gaps in American medical research that exist as a result of restrictive Bush-administration policies.  In a move which WSCN executive director Ed Fallone called “wise and necessary” WiCell is offering stem-cell lines that the federal government won’t.  These include newly discovered reprogrammed skin cells, and, perhaps, embryonic stem cells beyond the twenty-one lines authorized to receive federal funding.
