Evaluation of adenoviral vascular endothelial growth factor-activated chitosan/hydroxyapatite scaffold for engineering vascularized bone tissue using human osteoblasts: In vitro and in vivo studies.

Abstract excerpt

Bone tissue is dependent on an efficient blood supply to ensure delivery of nutrients and oxygen. One method to acquire a vascular-engineered bone tissue could be the use of an angiogenic gene-activated scaffold. In the current study, porous chitosan/hydroxyapatite (C/HA) scaffolds were fabricated via freeze-drying with desired pore size, and then combined with the adenoviral vector encoding vascular endothelial...
