Cell attachment, collagen binding, and receptor analysis on bovine articular chondrocytes

The purpose of this study was to investigate collagen receptors on primary bovine articular chondrocytes from full-thickness and different layers of bovine articular cartilage. Cytometric studies with antibodies showed that approximately 56% of the chondrocytes from the superficial layer and 29% of the chondrocytes from the deep layer bound anti-annexin V. A similar tendency was found for alpha5 and beta1 integrin antibodies. Flow cytometric...
