Silk fiber reinforcement modulates in vitro chondrogenesis in 3D composite scaffolds.

The limited self-regenerative capacity of adult cartilage has steered the upsurge in tissue engineered replacements to combat the problem of osteoarthritis. In the present study, the potential of fiber-reinforced silk composites from mulberry (Bombyx mori) and non-mulberry (Antheraea assamensis) silk has been investigated for cartilage tissue engineering. The fabricated composites were physico-chemically characterized and analyzed for cellular viability, proliferation, extracellular matrix formation and immunocompatibility.

Biomimetic, Osteoconductive Non-mulberry Silk Fiber Reinforced Tricomposite Scaffolds for Bone Tissue Engineering.

Composite biomaterials as artificial bone graft materials are pushing the present frontiers of bioengineering. In this study, a biomimetic, osteoconductive tricomposite scaffold made of hydroxyapatite (HA) embedded in non-mulberry Antheraea assama (A. assama) silk fibroin fibers and its fibroin solution is explored for its osteogenic potential.
