Main Methods:

  • Developed an on-chip microflow control system combining the siphon effect for passive flow initiation.
  • Utilized a yarn flow resistor to regulate and adjust medium flow rates within microchannels.
  • Evaluated cell alignment and cytoskeletal arrangement of endothelial cells in microwell arrays under controlled flow conditions.

Main Results:

  • Achieved adjustable medium flow rates in the range of a few hundred microliters per hour.
  • Demonstrated the feasibility of the system for microfluidic cell culture.
  • Observed effects of controlled flow on endothelial cell alignment and cytoskeletal arrangement.

Conclusions:

  • The developed on-chip technology offers a simple and efficient solution for controllable, long-term media delivery in microfluidic cell culture.
  • This method overcomes limitations of existing technologies, paving the way for advanced microfluidic cell-based applications.
  • The system's ability to influence cell behavior highlights its potential for studying cellular responses to flow dynamics.
