Area of Science:

  • Biomaterials Science
  • Cell Biology
  • Microfluidics

Background:

  • Microfluidic devices are crucial for cell-based research.
  • Traditional microfluidic materials may not accurately mimic in vivo cellular environments.
  • Gelatin offers biocompatibility but requires crosslinking for structural integrity.

Purpose of the Study:

  • To develop a novel microfluidic device fabrication method using naturally crosslinked gelatin.
  • To assess the suitability of gelatin microfluidic devices for adherent cell culture and analysis.
  • To investigate the impact of flexible gelatin microchannels on cell morphology compared to rigid substrates.

Main Methods:

  • Fabrication of microfluidic devices from gelatin using transglutaminase crosslinking.

  • Culture of normal murine mammary epithelial cells within the microchannels.
  • Comparative analysis of cell morphology on flexible gelatin versus rigid tissue culture plastic.

    • Main Results:

    • Successfully fabricated microfluidic devices from crosslinked gelatin.
    • Demonstrated minimal autofluorescence, ensuring compatibility with fluorescent imaging.
    • Achieved successful culture of adherent murine mammary epithelial cells.
    • Observed significant differences in cell morphology in flexible gelatin microchannels compared to rigid substrates.

    Conclusions:

    • Naturally crosslinked gelatin is a viable material for fabricating microfluidic devices for cell culture.
    • Flexible gelatin microchannels provide a microenvironment that influences cell morphology differently than rigid materials.
    • These devices offer a promising platform for studying cellular behavior and differentiation in more physiologically relevant conditions.
