Main Results:

  • PolyHIPE matrices were successfully prepared and coated with bioactive molecules.
  • Human neurons adhered to poly-d-lysine coated surfaces and extended processes.
  • Neurite outgrowth was significantly enhanced on matrices coated with both poly-d-lysine and laminin.

Conclusions:

  • Solid polystyrene scaffolds provide a promising 3D environment for neural cell growth and differentiation.
  • The developed matrices are robust, stable, and suitable for routine use in studying 3D cell behavior.
  • These findings support the potential of these scaffolds for advancing neural tissue engineering and in vitro neuroscience research.
