Separation and capture of circulating tumor cells from whole blood using a bypass integrated microfluidic trap array
Summary
This study introduces a microfluidic trap array for capturing circulating tumor cells (CTCs) from blood. This technology shows promise for early cancer metastasis detection and prognosis.
Area of Science:
- Biomedical Engineering
- Oncology
- Microfluidics
Background:
- Circulating tumor cells (CTCs) are crucial biomarkers for cancer metastasis.
- Effective methods for isolating CTCs from whole blood are needed for early cancer detection and prognosis.
Purpose of the Study:
- To develop and evaluate a novel microfluidic trap array for the separation and capture of CTCs from whole blood.
- To assess the potential of this device for early cancer metastasis prognosis.
Main Methods:
- A microfluidic device with a series array of microfluidic branches was designed.
- The device utilizes differential flow rates between bypass and trap channels to isolate CTCs.
- Cellular separation is based on cell size relative to trap outlet dimensions.
Main Results:
- The microfluidic trap array successfully captured CTCs from the whole blood of a mouse model with advanced metastasis.
- The device demonstrated effective separation of CTCs based on size and flow resistance principles.
Conclusions:
- The bypass-integrated microfluidic trap array is a viable tool for CTC isolation.
- Further development could establish this technology as a valuable method for early cancer metastasis prognosis.
