Summary: The development of highly porous cell supportive polymeric scaffolds with sufficient mechanical strength has always been a challenging task in tissue engineering. Air-jet spinning is an upcoming alternative approach for generating loosely arranged nanofibrous scaffolds within short time. In this study, polycaprolactone (PCL) tissue engineering scaffolds loaded with diamond nanosheets (DNS) were fabricated by air-jet spinning, and the inclusion of DNS improved the mechanical strength of the scaffolds. In vitro and in vivo studies demonstrated the high biocompatibility of PCL-DNS scaffolds, making them suitable for tissue engineering applications.

Summary: In this study, highly innovative nanoscale beta-tricalcium phosphate (β-TCP)-laden gelatin methacryloyl/polycaprolactone (GelMA/PCL-TCP) photocrosslinkable composite fibrous membranes were fabricated via electrospinning for guided bone regeneration (GBR). The composite microfibers showed a uniform porous network and successful integration of β-TCP particles. The GelMA/PCL-TCP membranes exhibited enhanced cell attachment, proliferation, mineralization, and osteogenic gene expression in alveolar bone-derived mesenchymal stem cells (aBMSCs) compared to pure PCL and GelMA/PCL. Furthermore, the GelMA/PCL-TCP membrane promoted robust bone regeneration in rat calvarial critical-size defects, demonstrating remarkable osteogenesis compared to PCL and GelMA/PCL groups. Overall, the electrospun GelMA/PCL-TCP composite showed great potential as a promising membrane for guided bone regeneration.
