Modification of Decellularized Goat-Lung Scaffold with ChitosanNanohydroxyapatite Composite for Bone Tissue Engineering Applications

الملخص EN

Decellularized goat-lung scaffold was fabricated by removing cells from cadaver goat-lung tissue, and the scaffold was modified with chitosan/nanohydroxyapatite composite for the purpose of bone tissue engineering applications.

MTT assay with osteoblasts, seeded over the chitosan/nanohydroxyapatite-modified decellularized scaffold, demonstrated significantly higher cell growth as compared to the decellularized scaffold without modification.

SEM analysis of cell-seeded scaffold, after incubation for 7 days, represented a good cell adhesion, and the cells spread over the chitosan/nanohydroxyapatite-modified decellularized scaffold.

Expression of bone-tissue-specific osteocalcin gene in the osteoblast cells grown over the chitosan/nanohydroxyapatite-modified decellularized scaffold clearly signifies that the cells maintained their osteoblastic phenotype with the chitosan/nanohydroxyapatite-modified decellularized scaffold.

Therefore, it can be concluded that the decellularized goat-lung scaffold-modified with chitosan/nanohydroxyapatite composite, may provide enhanced osteogenic potential when used as a scaffold for bone tissue engineering.
