    Chondrocytes were isolated from articular cartilage biopsy and were cultivated in vitro. Approximately 30 million of cultured chondrocytes per ml were incorporated with autologous plasma-derived fibrin to form three-dimensional construct. Full-thickness punch hole defects were created in lateral and medial femoral condyles. The defects were implanted either with the autologous 'chondrocytes-fibrin' construct (ACFC), autologous chondrocytes (ACI) or fibrin blank (AF). Sheep were euthanized after 12 weeks. The gross morphology of all defects treated with ACFC implantation, ACI and AF exhibited median scores which correspond to a nearly normal appearance according to the International Cartilage Repair Society (ICRS) classification. ACFC significantly enhanced cartilage repair compared to ACI and AF in accordance with the modified O'Driscoll histological scoring scale. The relative sulphated glycosaminoglycans content (%) was significantly higher (p < 0.05) in ACFC when compared to control groups; ACI vs. fibrin only vs. untreated (blank). Results showed that ACFC implantation exhibited superior cartilage-like tissue regeneration compared to ACI. If the result is applicable to the human, it possibly will improve the existing treatment approaches for cartilage restoration in orthopaedic surgery.

    Avian demineralized bone matrix (ADBM) powder prepared from chicken, pigeon, and turkey sources induced bone formation via endochondral and intramembranous processes, as in mammalian studies. There were no significant differences in percentage of new bone, percentage of cartilage, surface-forming osteoblast area, or osteoclast count between gaps treated with chicken, pigeon, and turkey DBM. However, there was a significantly (p<0.05) higher percentage of inflammatory area in gaps treated with chicken DBM than in gaps treated with pigeon DBM.

    This study was performed to determine the microscopic biological response of human nasal septum chondrocytes and human knee articular chondrocytes placed on a demineralized bovine bone scaffold. Both chondrocytes were cultured and seeded onto the bovine bone scaffold with seeding density of 1 x 105 cells per 100 microl/scaffold and incubated for 1, 2, 5 and 7 days. Proliferation and viability of the cells were measured by mitochondrial dehydrogenase activity (MTT assay), adhesion study was analyzed by scanning electron microscopy and differentiation study was analyzed by immunofluorescence staining and confocal laser scanning electron microscopy. The results showed good proliferation and viability of both chondrocytes on the scaffolds from day 1 to day 7. Both chondrocytes increased in number with time and readily grew on the surface and into the open pores of the scaffold. Immunofluorescence staining demonstrated collagen type II on the scaffolds for both chondrocytes. The results showed good cells proliferation, attachment and maturity of the chondrocytes on the demineralized bovine bone scaffold. The bovine bone being easily resourced, relatively inexpensive and non toxic has good potential for use as a three dimensional construct in cartilage tissue engineering.
