Area of Science:

• Biomaterials Science
• Tissue Engineering
• Neuroscience

Background:

• Traditional 2D scaffolds for nerve cell culture do not mimic the native extracellular matrix.
• Tissue engineering scaffolds offer a promising approach for neuronal repair in nerve injuries.
• Developing advanced scaffolds is crucial for improving nerve regeneration outcomes.

Purpose of the Study:

• To fabricate highly ordered 3D scaffolds using melt electrospinning writing for nerve cell culture.
• To investigate the effects of various surface modifications on nerve cell growth.
• To determine the optimal surface modification strategy for promoting nerve cell proliferation and extension.

Main Methods:

• Fabrication of 3D scaffolds with controlled microstructures and geometries via melt electrospinning writing.
• Surface modification of scaffolds using plasma treatment, poly-D-lysine (PDL) coating, and laminin (LM) coating.
• Evaluation of PC12 cell growth on scaffolds with different surface modifications (plasma, PDL, LM, PDL+LM).

Main Results:

• Scaffolds with double poly-D-lysine (PDL) and laminin (LM) coatings after plasma treatment significantly enhanced PC12 cell growth.
• The synergistic effect of PDL and LM coatings was observed to be most effective in promoting nerve cell proliferation.
• This study provides quantitative data on the impact of different surface modifications on nerve cell behavior.

Conclusions:

• The developed 3D scaffolds with optimized surface modification serve as a versatile platform for nerve cell culture.
• The synergistic combination of PDL and LM coatings shows significant potential for enhancing neuronal repair and recovery from peripheral nerve injury.
• This research contributes to advancing nerve tissue engineering strategies for regenerative medicine.
