Summary
This study developed micropatterned polycaprolactone (PCL) scaffolds using electrospinning, enhancing fibroblast cell behavior and promoting wound healing. The novel scaffolds accelerated wound closure and improved tissue regeneration compared to flat PCL nanofibers.
Area of Science:
- Biomaterials Engineering
- Tissue Engineering
- Regenerative Medicine
Background:
- Developing advanced wound healing materials is crucial for effective tissue regeneration.
- Structural scaffolds can influence cell behavior and tissue integration.
- Micropatterning offers a strategy to guide cellular responses in regenerative applications.
Purpose of the Study:
- To fabricate and evaluate a novel structural scaffold with micropatterned nanofibers for enhanced wound healing.
- To compare the in vitro and in vivo performance of micropatterned scaffolds against flat nanofibers.
- To assess the scaffold's impact on fibroblast proliferation, orientation, and wound closure rates.
Main Methods:
- Fabrication of polycaprolactone (PCL) nanofibers using electrospinning combined with a triangular prism template.
- In vitro assessment of fibroblast cell proliferation and orientation on micropatterned versus flat scaffolds.
- In vivo wound healing studies in animal models to evaluate wound closure and tissue regeneration.
- Histological analysis of healed tissue to examine cellular infiltration, collagen deposition, and inflammation.
Main Results:
- The structural scaffold exhibited significantly higher fibroblast cell proliferation and orientation (70%) with an aspect ratio of 13.48 ± 2.73 compared to flat nanofibers.
- The micropatterned scaffold accelerated wound closure to 92.17% by day 14.
- Histology revealed advanced epithelization, denser and horizontally aligned fibroblast and collagen fibers, and mild inflammation in healed wounds.
Conclusions:
- Micropatterned PCL scaffolds effectively stimulate fibroblast cell behavior, including proliferation and alignment.
- These structural scaffolds demonstrate significant potential for accelerating wound healing and improving tissue regeneration.
- The combination of electrospinning and templating offers a viable method for creating advanced biomaterials for regenerative medicine.
