This microscopy image provided by Dr. Carl June, shows immune
system T-cells, center, binding to beads which cause the cells
to divide. The beads, depicted in yellow, are later removed,
leaving pure T-cells which are then ready for infusion to the
cancer patients. Scientists are reporting the first clear
success with gene therapy to treat leukemia, using the patients'
own blood cells to hunt down and wipe out their cancer. They've
only done it in three patients so far, but the results were
striking: two appear cancer-free up to a year after treatment,
and the third had a partial response. Scientists are already
preparing to try the approach in other kinds of cancer. More
