 | | Opponents of ES cell research hold that human life begins as soon as an egg is fertilized, and they consider a human embryo to be a human being. |
 | | Proponents of ES cell research, meanwhile, generally praised the president for allowing some research to go forward, but criticized the restriction to existing cell lines as too strict, questioning whether enough research will be allowed. |
 | | In September 2001, the National Academy of Sciences released a new report on stem cells which concluded that public funding should be made available for research on both embryonic and adult cells, and that in the long run, it will be necessary to derive new embyronic stem cell lines. |
