What are circulating tumor cells?
Circulating tumor cells (CTCs) are cancer cells that have detached from the primary tumor and circulate in the bloodstream.
Why is it important to isolate viable CTCs?
Isolating viable CTCs allows for analysis of cancer characteristics and development of personalized treatment options.
How does the isolation technique work?
The technique uses a functionalized micro tube with E-selectin and antibodies to capture CTCs from blood samples.
What are the advantages of this method?
It is straightforward, uses common materials, and mimics natural cell capture processes.
What can isolated CTCs be used for?
Isolated CTCs can be used for drug susceptibility testing and to analyze cell marker expression.
Who demonstrated the procedure?
The procedure was demonstrated by Mike King, an associate professor, and Jeff Madison, a senior technician.
