As the global population grows and ages, the occurrence of critical-size bone injuries is expected to rise, increasing demand for alternatives to traditional treatments such as metal implants and bone grafts, which are associated with complications like donor site pain, infection risk and poor tissue integration. This study aimed to develop biodegradable textile scaffolds with enhanced bioactivity by coating them with bioceramics for potential use in bone tissue engineering (BTE). Hydroxyapatite (HA) and carbonated hydroxyapatite (CHA) were synthesised using eggshells as a sustainable calcium source and characterised by Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscopy (SEM). Polyhydroxyalkanoate (PHA) monofilaments were braided into textile scaffolds and coated with HA, CHA or a 50/50 mix and efficiency of coatings was evaluated by FTIR and SEM. Scaffold biocompatibility was tested in vitro using human mesenchymal stem cells. Early cell attachment on uncoated and coated scaffolds (HA, CHA and HA+CHA) was evaluated at 3 hours and 4 days using nuclei and actin staining, while long-term biocompatibility and osteogenic differentiation were assessed at 2 and 3 weeks were assessed for uncoated, HA and CHA-coated scaffolds using cell viability assays, fluorescence imaging of live cells and cytoskeleton, SEM and alkaline phosphatase (ALP) staining. HA and CHA synthesis yielded of45% and 49%, respectively. All coated scaffolds improved early cell attachment and spreading over uncoated control scaffolds. Between week 2 and 3, cell viability increased in all groups with live cells observed on all scaffolds at both time points, confirming biocompatibility. HA-coated scaffolds showed the highest ALP activity and osteoblast-like morphology, indicating enhanced osteogenic differentiation. These findings highlight the potential of eggshell-derived ceramic coatings on biodegradable textile scaffolds as an effective and sustainable approach for bone regeneration.
