Researchers developed a cost-effective method to create micro-grooved microfluidic chips that align cells in 3D cultures. This technique enhances skeletal muscle differentiation, offering improved models for tissue engineering and drug screening.

Area of Science:

  • Biomaterials Engineering
  • Cellular Engineering
  • Microfluidics

Background:

  • Conventional 2D microfluidic cultures have limitations in mimicking native cellular environments.
  • 3D microfluidic systems offer enhanced cellular function but often lack topographical features.
  • Micro/nano-grooves are known to benefit cardiac, skeletal, and neuronal cell development.

Purpose of the Study:

  • To develop a scalable and cost-effective method for incorporating micro-topographical cues into microfluidic chips.
  • To investigate the alignment of 2D cell monolayers and 3D cellular constructs using micro-grooved substrates.
  • To evaluate the impact of aligned 3D cellular constructs on skeletal muscle differentiation.

Main Methods:

  • Utilized commercially available optical media for replica molding to create polydimethylsiloxane (PDMS) micro-grooved substrates.

  • Plasma-bonded PDMS micro-grooved substrates to microfluidic chips for large-scale production.
  • Cultured C2C12 mouse myoblasts in 3D within microfluidic chips featuring aligned micro-grooves.

    • Main Results:

    • Successfully produced large surface areas of PDMS micro-grooved substrates and integrated them into microfluidic chips.
    • Demonstrated alignment of both 2D cell monolayers and 3D cellular constructs within the microfluidic chips.
    • Observed preferential orientation of actin cytoskeleton and nuclei along micro-grooves in aligned 3D constructs.
    • Showed enhanced skeletal muscle differentiation in aligned C2C12 3D cellular constructs compared to randomly aligned ones.
    • Confirmed cell alignment in 3D constructs without direct contact with micro-grooves, due to topography and fluid shear stress synergism.

    Conclusions:

    • The novel method enables routine inclusion of micro-topographical cues in 2D and 3D microfluidic cultures.
    • This approach facilitates the generation of physiologically relevant models for tissue morphogenesis and drug screening.
    • Micro-grooved 3D microfluidic systems show promise for advancing regenerative medicine and pharmaceutical research.
