FIG. 1.

The effect of treatments on the cellular appearance of superficial zone articular chondrocytes. Primary bovine superficial zone chondrocytes were treated and cultured for 4 days. Chondrocyte morphology was examined under a light microscope at day 4 of treatment. The control displayed a flattened, fibroblast-like appearance. Treated chondrocytes had a similar appearance to the controls. Chondrocytes were treated according to the corresponding treatment labels above the image. Scale bar=50 μm.
