The Rotating-Wall Vessel (RWV) was used to culture chondrocytes for 36 d to observe the influence of low-shear and quiescent culture conditions allowing three-dimensional freedom on growth, differentiation, and extracellular matrix formation. Chondrocytes were freshly isolated from bovine cartilage and placed into the RWV with Cytodex-3 microcarriers. Nonadherent petri dishes were initiated with microcarriers as representative of standard culture conditions. In the RWV, large three-dimensional aggregates (5-7 mm) were formed in suspension. In addition, a large sheet of matrix adhered to the oxygenator core and vessel endcaps. Petri dish culture resulted in the formation of sheets of chondrocytes with no matrix production. Immunocytochemical analyses on histologic sections of tissue obtained from the RWV and the petri dish controls were performed with antibodies against fibronectin, collagen II, chondroitin-4-sulfate, chondroitin-6-sulfate, and vimentin. Results demonstrated increased signal in the RWV material while the petri dishes demonstrated a slight decrease in signal. In addition, differentiated chondrocytes were observed in sections of RWV material through 36 d, while few were observed in the sections of petri dish material. These results indicate that the unique conditions provided by the RWV afford access to cellular processes that signify the initiation of differentiation as well as production of normal matrix material.
