A Paradigm Shift in Stem Cell Research?
Ricki Lewis | Mar 5, 2000 | 9 min read
Photo: E.D. Laywell, UT MemphisMultipotent clones of cells derived from the adult human brain With the promises and challenges of stem cell research in the headlines, visions of artificial livers dance in the public's eye. Bioethicists, politicians, and citizens alike continue to debate whether public funds should be used to obtain cells from human embryos and fetuses. On the scientific front, however, the implications of stem cell research are even more profound than offering replacement parts.
