Scientists are reporting today that they have overcome a major obstacle to using a promising alternative to embryonic stem cells, bolstering the prospects for bypassing the political and ethical tempest that has embroiled hopes for a new generation of medical treatments. The researchers said they found a safe way to coax adult cells to regress into an embryonic state, alleviating what had been the most worrisome uncertainty about developing the cells into potential cures.
