Stem cells found in amniotic fluid, which Bush suggested “seem to do what embryonic cells can,” are simply not as versatile as the embryonic stem cells they supposedly mimic. The same problem is even more true of adult stem cells, which have successfully been used for some treatments but which will never be usable for others. Although the Bush Administration has argued that there have been more successful treatments with adult stem cells than with embryonic ones...
...only dozens of cells large. Most of these migrating cells die during the journey. Others are more menacing--pioneers programmed to seed new growth in distant tissues. Either way, as epithelial cells--closely packed, multilayered cells of which most solid tumors are made--they are oddballs in their new fluid environment. "It's like splitting a deck of cards into red and black suits," says Dr. Daniel Hayes, director of the breast-cancer program at the University of Michigan, about separating these epithelial tumor cells from the blood. "Blood is made up of different tissues, so we look for epithelial...
...what a wholesale move to a perennially backlogged system could bring.
