This study introduces novel 3D scaffolds with microchannels and porous layers for enhanced cell culture. Dynamic perfusion significantly boosts cell proliferation and viability across all scaffold layers.

Area of Science:

  • Biomaterials Engineering
  • Tissue Engineering
  • Cell Biology

Background:

  • Traditional 3D cell culture models face challenges in nutrient distribution and data acquisition.
  • Developing advanced scaffolds is crucial for mimicking in vivo environments and improving cell growth.

Purpose of the Study:

  • To propose and investigate a novel 3D scaffold design with stacked porous layers and integrated microchannels.
  • To evaluate the efficacy of these scaffolds for cell culture under static and dynamic conditions.
  • To demonstrate the potential for localized data retrieval from within the scaffold structure.

Main Methods:

  • Fabrication of 3D scaffolds from Poly(l-lactic acid) (PLLA) sheets with microchannels and inner porosity.
  • Cell culturing of C2C12 pre-myoblasts and A4-4 cells on stacked scaffold layers.

  • Comparison of cell proliferation, viability, and nutrient diffusion under static and dynamic (perfusion) conditions.

    • Main Results:

    • Static culture showed limited cell proliferation due to nutrient diffusion constraints but confirmed inter-layer cell viability and interaction.
    • Dynamic culture with medium perfusion through microchannels significantly enhanced nutrient availability.
    • Perfusion drastically increased cell proliferation across all layers of the 3D scaffold.

    Conclusions:

    • The proposed 3D scaffold design effectively supports cell viability and inter-layer communication through diffusion.
    • Microchannel-mediated perfusion is a critical factor for overcoming nutrient limitations and promoting robust cell proliferation in multi-layered scaffolds.
    • These scaffolds offer a promising platform for advanced tissue engineering applications and in situ monitoring.
