This study dealt with developing cost?effective electroconductive scaffolds integrating carboxy functionalized graphene nanoplatelets (GNPs) into a Polycaprolactone (PCL)?collagen matrix. Utilizing electrical stimulation (ES), the study assesses the scaffolds? ability to enhance neuronal differentiation from mesenchymal stem cells (MSCs). Aligned GNP?reinforced PCL?Collagen scaffolds show notable MSC differentiation under ES.The internal electric field of the human body plays a crucial role in regulating various biological processes, such as, cellular interactions, embryonic development and the healing process. Electrical stimulation (ES) modulates cytoskeleton and calcium ion activities to restore nervous system functioning. When exposed to electrical fields, stem cells respond similarly to neurons, muscle cells, blood vessel linings, and connective tissue (fibroblasts), depending on their environment. This study develops cost?effective electroconductive scaffolds for regenerative therapy. This was achieved by incorporating carboxy functionalized graphene nanoplatelets (GNPs) into a Polycaprolactone (PCL)?collagen matrix. ES was used to assess the scaffolds? propensity to boost neuronal differentiation from MSCs. This study reported that aligned GNP?reinforced PCL?Collagen scaffolds demonstrate substantial MSC differentiation with ES. This work effectively develops scaffolds using a simple, cost?effective synthesis approach. The direct coupling approach generated a homogeneous electric field to stimulate cells cultured on GNP?reinforced scaffolds. The scaffolds exhibited improved mechanical and electrical characteristics, as a result of the reinforcement with carbon nanofillers. In vitro results suggest that electrical stimulation helps differentiation of mesenchymal stem?like cells (MSC?like) towards neuronal. This finding holds great potential for the development of effective treatments for tissue injuries related to the nervous system.
