A The composite fibres fabricated with a core–shell design are distinctive, and a fuzzy boundary between the core and shell implies good miscibility [148]. B mBMSCs were able to attach and spread well on the constructs [133]. C H&E staining results indicated that the PCL/gelatin composite electrospun scaffolds with crater-like structures showed a significantly higher affinity for cell infiltration [135]. D Micro-CT analysis showed that the composite scaffold group had more bone in-growth than the pure gelatin group [137]
