Morphology of human chondrocytes at passage 0–2 on G5 and PS surfaces on day 7 (a). Scale bars show 100 μm. Cell numbers after cultivation of human chondrocytes on G5 and PS surfaces on day 7 (b). Data represent average values with the standard deviation determined from triplicate independent experiments. Differences among the data sets were considered significant at **p < 0.01
