Characteristics of the implants. a Confirmation of hollow cavity of the cage. The hollow cavity of the cage was confirmed by the injection of blue ink mixed Biogel. The maximum loading capacity of the PLA cage was 35 μL. b SEM images of the scaffold. The surface and inner cavity of the cage were well covered with porous structured Biogel. c FT-IR spectroscopy result of scaffold. The spectroscopy indicated the Biogel was composed of alginate and gelatin. d The unconfined compression test result. The cage and cage+Biogel groups showed significantly higher compressive modulus than the Biogel group. No significant difference was found between cage and cage+Biogel groups
