Well this is interesting http://www.nih.gov/news/health/may2015/nibib-18.htm" rel="nofollow - http://www.nih.gov/news/health/may2015/nibib-18.htm
From the article
Researchers have developed a microfluidic chip that can capture rare clusters of circulating tumor cells, which could yield important new insights into how cancer spreads. The work was funded by the National Institute of Biomedical Imaging and Bioengineering (NIBIB), part of the National Institutes of Health.
Circulating tumor cells (CTCs) are cells that break away from a tumor and move through a cancer patient’s bloodstream. Single CTCs are extremely rare, typically fewer than 1 in 1 billion cells. These cells can take up residence in distant organs, and researchers believe this is one mode by which cancer spread
Even less common than single CTCs are small groups of CTCs, or clusters. While the existence of CTC clusters has been known for more than 50 years, their prevalence in the blood as well as their role in metastasis has not been thoroughly investigated, mostly because they are so elusive. However, recent advances in biomedical technologies that enable researchers to capture single CTCs have renewed interest in CTC clusters, which are occasionally captured along with single CTCs.
Now, researchers led by Mehmet Toner, Ph.D., professor of surgery (biomedical engineering) at the Massachusetts General Hospital (MGH) and the Harvard-MIT Division of Health & Sciences Technology, report the development of a novel microfluidic chip that is specifically designed for the efficient capture of CTC clusters from whole, unprocessed blood.
