Area of Science:

  • Biomaterials Science
  • Tissue Engineering
  • Regenerative Medicine

Background:

  • Tissue engineering offers solutions for damaged tissue repair, particularly in skin diseases.
  • Synthetic degradable polymers like polylactic acid (PLA) are used in medical scaffolds but have poor cellular adhesion.
  • Enhancing scaffold biocompatibility is crucial for effective tissue regeneration.

Purpose of the Study:

  • To improve the biocompatibility and cellular adhesion of polylactic acid (PLA) nanofibers for tissue engineering applications.
  • To investigate the potential of gelatin modification to enhance PLA scaffolds for fibroblast attachment and proliferation.
  • To explore the efficacy of PLA/gelatin nanofiber scaffolds in promoting skin wound healing.

Main Methods:

  • Electrospinning of polylactic acid (PLA) and gelatin blends in varying compositions (3:7 and 7:3) using hexafluoroisopropanol (HFIP) solvent.
  • Characterization of nanofiber scaffold properties using Fourier transform infrared (FT-IR) spectroscopy and scanning electron microscopy (SEM).
  • Assessment of fibroblast attachment and viability on modified PLA/gelatin scaffolds compared to pure PLA or gelatin scaffolds.

Main Results:

  • The PLA/gelatin 7/3 nanofiber scaffold demonstrated superior suitability for fibroblast attachment and viability compared to pure PLA or gelatin scaffolds.
  • Fourier transform infrared (FT-IR) spectroscopy and scanning electron microscopy (SEM) confirmed the structural and chemical modifications of the blended scaffolds.
  • The modified scaffolds exhibited enhanced biocompatibility, promoting cellular interaction essential for tissue repair.

Conclusions:

  • Modification of polylactic acid (PLA) nanofibers with gelatin significantly enhances their biocompatibility and cellular adhesion properties.
  • The PLA/gelatin 7/3 nanofiber scaffold presents a promising alternative for improving skin wound healing through enhanced fibroblast support.
  • This study highlights the potential of combining synthetic polymers with natural biomaterials in tissue engineering for advanced therapeutic applications.
