| Who could argue that the money and brain power devoted to cloning stem cells could not be better used on something else? |
| The purified stem cells normally give rise to cells that mature into red blood cells and white blood cells. |
| They found two genes switched on in the amniotic epithelial cells that heretofore were believed to only be expressed in embryonic stem cells. |
| The independent and simultaneous malignant transformation of 4 different stem cells is difficult to imagine in such a small tumor. |
| Scientists have long known that bone marrow stem cells regenerate blood cells. |
| Scientists were harvesting these stem cells from embryos left over from IVF treatments or using aborted embryos. |
