Background:

• C2C12 myoblasts are a common model for skeletal muscle research.
• 3D bioscaffolds are crucial for tissue engineering applications.
• Graphene-based materials offer unique properties for biomedical applications.

Purpose of the Study:

• To investigate the use of 3D graphene foam as a bioscaffold for C2C12 myoblast differentiation.
• To assess the biocompatibility of graphene foam for muscle cell growth.
• To determine the effect of electrical stimulation on myotube functionality.

Main Methods:

• C2C12 myoblasts were cultured on bare and laminin-coated 3D graphene foam.
• Cell differentiation was assessed by myotube heavy chain protein expression.
• Cell functionality was evaluated using Ca2+ fluorescence.
• Pulsed electrical stimuli were applied to the graphene foam scaffolds.

Main Results:

• Graphene foam supported C2C12 myoblast growth and differentiation into myotubes.
• Both bare and laminin-coated graphene foam were biocompatible.
• Electrical coupling enhanced cell activity.
• Electrical stimulation induced myotube contraction and substrate movement (>100 µm).

Conclusions:

• 3D graphene foam is a viable biocompatible platform for muscle tissue engineering.
• Electrical stimulation of graphene foam enhances myotube functionality.
• These findings support the development of graphene-based platforms for regenerative medicine.
