Area of Science:

  • Biomedical Engineering
  • Cancer Research
  • Microfluidics

Background:

  • Microfluidic devices (MDs) offer novel methods for detecting circulating tumor cells (CTCs).
  • Current CTC detection methods often result in heterogeneous populations, requiring complex, costly, and time-consuming downstream processing for phenotype identification.
  • There is a need for efficient and cost-effective approaches for CTC classification.

Purpose of the Study:

  • To investigate the potential of a hyperuniform micropost microfluidic device (MD) for cost-effective and efficient circulating tumor cell (CTC) classification.
  • To develop and validate a computational framework combining mathematical modeling and machine learning for CTC phenotype analysis.
  • To assess the capability of the proposed approach in distinguishing between different CTC phenotypes based on cell trajectory.

Main Methods:

  • Developed a cell-based modeling framework to simulate CTC dynamics within erythrocyte-laden plasma flow in a microfluidic channel.
  • Utilized mathematical modeling of fluid-structure interactions to generate a comprehensive dataset of CTC trajectories.
  • Employed machine learning techniques, specifically Convolutional Neural Networks (CNN) and Recurrent Neural Networks (RNN), for CTC phenotype classification based on trajectory data.

Main Results:

  • Generated a large dataset of simulated CTC trajectories representing two distinct CTC phenotypes.
  • Demonstrated the effectiveness of CNN and RNN models in accurately classifying CTC phenotypes using trajectory data.
  • Validated the potential of the hyperuniform micropost MD design for distinguishing between CTC phenotypes.

Conclusions:

  • The hyperuniform micropost microfluidic device combined with machine learning analysis presents a promising, cost-effective strategy for CTC classification.
  • This approach offers a potential avenue for improved early cancer detection through accurate identification of circulating tumor cell phenotypes.
  • The study highlights the synergy between computational modeling and machine learning in advancing microfluidic-based diagnostics.
