Abstract

Repair of substantial cranial defects in adults and children may be compromised due to limitations in donor bone stocks for autologous grafts. We evaluated the capability of autologous adipose-derived mesenchymal cells (ADCs) in combination with polylactic acid (PLA) scaffolds to regenerate bone in a critical-sized skull defect. Thirty adult New Zealand White rabbits were divided into six groups of five animals each: (1) PLA alone (control), (2) fibronectin-coated PLA, (3) PLA with ADCs, (4) fibronectin-coated PLA with ADCs, (5) PLA with osteogenically induced ADCs (osADCs), and (6) fibronectin-coated PLA with osADCs. All the animals were humanely killed after 6 weeks. X-ray, histology, and ..
