Gross view of tissue engineered cartilage and cell proliferation for each group.

<p>The DNA content of the cells retrieved from the different scaffolds at different time points during in vitro culture was determined. The DNA content of the PHBV/BG group was significantly higher than that of the PHBV group. The results of the MTT assay showed that the incorporation of BG enhanced chondrocyte proliferation. The chondrocyte-scaffold constructs were harvested after 3 weeks of culture <i>in vitro</i>, and it was observed that the chondrocyte-scaffold constructs formed cartilage-like tissue.
