Bone Regeneration

The current research focuses on developing novel cell based vascularized bone grafts to promote bone regeneration for critical sized bone defect injury.

Tissue engineering approaches combined with recent advances in stem cell biology may enable the growth of bone grafts for the treatment and repair of critical-sized orthopedic defects which may arise due to trauma, infection, tumor resections or congenital abnormalities. This project aims to develop potential cell based therapies for critical sized bone defect injury to enhance bone regeneration and functional recovery in a translational model.
