3D cell culture scaffolds designed as hard polymer fibre constructs:
Such design provides a favourable environment for cell attachment and proliferation. The round fibre and pore morphology follows a random structure of natural extracellular matrix (as compared to straight/aligned fibre and filament structures). Large pores allow for an efficient cell distribution throughout the entire scaffold height.
