Stem cell therapy triggers tumor
Tia Ghose | Feb 17, 2009 | 3 min read
A neural stem cell transplant from fetal cells performed in Russia led to a brain tumor in a teenage boy, researchers in this week's PLoS Medicine report, raising concerns about the safety of neural stem cells treatments. MRI of brain lesion, courtesy of PLoS MedicineThe researchers confirmed that the cancer originated from the donor tissue, not the boy's own cells. This is the first report of cancer following fetal neural stem cell transplant. However, outside experts raised concerns about th

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.
