The aim of this study was to investigate the effects of alginate and agarose on the response of bone marrow stromal cells (BMSCs) to chondrogenic stimuli. Rat BMSCs were expanded in monolayer culture with or without FGF-2 supplementation. Cells were then seeded in 2% alginate and agarose gels and cultured in media with or without TGF-beta1 or dexamethasone(More)
OBJECTIVE To compare matrix composition and glycosaminoglycan (GAG) fine structure among five scaffolds commonly used for in vitro chondrocyte culture and cartilage tissue engineering. DESIGN Bovine articular chondrocytes were seeded into agarose, alginate, collagen I, fibrin and polyglycolic acid (PGA) constructs and cultured for 20 or 40 days. In(More)
Interactions between bone and cartilage formation are critical during growth and fracture healing and may influence the functional integration of osteochondral repair constructs. In this study, the ability of tissue-engineered cartilage constructs to support bone formation under controlled mechanical loading conditions was evaluated using a lapine hydraulic(More)
Cryogels are advantageous scaffolds for bone regeneration applications due to their high mechanical stability and macroporous structure. Anatomically, bone is composed of collagen and hydroxyapatite and during remodeling, these structural components are replaced. However, early forms of mineralization include calcium salts which take up to months to be(More)
