Fabrication of a Whitlockite/PLGA Scaffold with Hierarchical Porosity for Bone Repair.

Regenerating functional bone tissue in critical-sized defects remains a formidable issue. Bone-tissue engineering (BTE) scaffolds are emerging as potential alternatives to bone transplantation for the repair of bone defects. However, developing BTE scaffolds with unique bone-healing properties and natural bone porous structure is challenging.
