Metastatic cancer cells implode on protein contact

By attaching a cancer-killer protein to white blood cells, Cornell biomedical engineers have demonstrated the annihilation of metastasizing cancer cells traveling throughout the bloodstream.

The study, “TRAIL-Coated Leukocytes that Kill Cancer Cells in the Circulation,” was published online the week of Jan. 6 in the journal Proceedings of the National Academy of Sciences.

“These circulating cancer cells are doomed,” said Michael King, Cornell professor of biomedical engineering and the study’s senior author. “About 90 percent of cancer deaths are related to metastases, but now we’ve found a way to dispatch an army of killer white blood cells that cause apoptosis – the cancer cell’s own death – obliterating them from the bloodstream. When surrounded by these guys, it becomes nearly impossible for the cancer cell to escape.”

That is from the Cornell press release. I sure hope these results can be replicated. How difficult is the technique?
