The Coalition for the Advancement of Medical Research (CAMR) notes that 200 members of Congress have signed an open letter requesting that President Bush undo restrictive, anti-research stem cell legislation. Hundreds or thousands of distinct, viable stem cell lines will be needed for vigorous research into regenerative medicine. Thanks to this US administration (and despite generous privately funded efforts), there are currently fewer than fifty viable lines, most of which cannot be used. You can help remedy this situation by writing to your representatives - CAMR provides a web page to make this easy. Please take a few minutes today to make your voice heard.
