Area of Science:

  • Biomaterials Science
  • Tissue Engineering
  • Nanotechnology

Background:

  • Aligned collagen nanofibers in tendon provide a natural template for cell organization.
  • Developing cost-effective and accessible methods for fabricating nanostructured substrates is crucial for tissue engineering.
  • Traditional micro/nanofabrication tools can be expensive and complex.

Purpose of the Study:

  • To present an efficient and versatile method for fabricating nanostructured substrates using tendon.
  • To demonstrate the utility of these substrates in guiding directional cell growth and creating cell sheets.
  • To enable the creation of biocompatible nanostructured materials without specialized fabrication equipment.

Main Methods:

  • Tendon slices (10-50 µm thick) were prepared using a microtome to serve as scaffolds.
  • Soft lithography was employed to transfer tendon-derived nanostructures onto polystyrene films.
  • Cell adhesion, alignment, and growth on the nanostructured polystyrene were evaluated.

Main Results:

  • Highly aligned and uniform monolayer cell sheets were successfully obtained on tendon scaffolds.
  • Nanostructures from tendon were effectively replicated onto polystyrene films.
  • Cells cultured on the nanostructured polystyrene substrates exhibited good adhesion and alignment.

Conclusions:

  • The developed technique offers an accessible approach to fabricating nanostructured substrates from natural materials like tendon.
  • The nanostructured substrates exhibit excellent biocompatibility and mechanical stability, suitable for 3D tissue construction.
  • This method bypasses the need for traditional micro/nanofabrication tools, making it broadly applicable.
