Area of Science:

  • Biomaterials Science
  • Tissue Engineering
  • Regenerative Medicine

Background:

  • Electrospun fibers offer unique properties like high surface area and tunable porosity, mimicking the natural extracellular matrix.
  • These characteristics make them highly suitable for various applications, including tissue engineering.

Purpose of the Study:

  • To develop and evaluate bilayered tubular scaffolds using electrospun Poly ε-caprolactone (PCL) for vascular tissue engineering.
  • To assess the ability of these scaffolds to support endothelial cells and fibroblasts, crucial for vascular regeneration.

Main Methods:

  • Poly ε-caprolactone (PCL) was processed into bilayered tubular scaffolds via electrospinning.
  • Endothelial cells were seeded on the inner PCL/Gelatin layer, and fibroblasts on the outer PCL layer.
  • Cell phenotype, extracellular matrix production (collagen type I), and ultrastructural morphology (SEM) were analyzed.

Main Results:

  • Both endothelial cells and fibroblasts successfully colonized the respective scaffold layers.
  • Cells maintained their distinct phenotypes throughout the culture period.
  • The scaffolds demonstrated potential for supporting cell integration and function.

Conclusions:

  • The developed PCL-based electrospun scaffolds are effective in supporting distinct cell populations for vascular tissue engineering.
  • These findings support the hypothesis that PCL scaffolds are a promising candidate for vascular surgery applications.
