Cancer Trap

A new synthetic scaffold could help with the early detection of recurrence and metastasis in cancer patients. The device – readily accessible underneath the skin – functions as a metastatic niche to attract circulating cancer cells. “Analysis of collected cells indicates unique cancer cell properties at metastatic sites relative to the primary tumor, or cells in circulation,” says Lonnie Shea, Professor of Bioengineering at the University of Michigan and senior author of the paper (1).

Biopsies of the scaffolds in mouse models revealed 635 cancer cell genes, 10 of which helped to identify whether or not the cancer had begun to spread. “Liquid biopsy has shown promise for monitoring disease, but our approach is distinct because it captures tumor cells that have left the vasculature,” explains Shea. The cancer traps are attractive when compared with invasive biopsies – and Shea sees a future in which sensors continuously monitor the implant in high-risk patients.

About the Author(s)

Luke Turner

While completing my undergraduate degree in Biology, I soon discovered that my passion and strength was for writing about science rather than working in the lab. My master’s degree in Science Communication allowed me to develop my science writing skills and I was lucky enough to come to Texere Publishing straight from University. Here I am given the opportunity to write about cutting edge research and engage with leading scientists, while also being part of a fantastic team!
