Morphometric and biochemical analyses in rAAV-transduced chondrocytes in vitro . Cells were transduced with rAAV-lacZ or rAAV-hTGF-β as described in Figure 1 and maintained in culture for up to 21 days. The samples were then fixed and histologically processed at the denoted time points to monitor the % of BrdU labeling (A) and the contents of DNA (B), proteoglycans (C), type-II (D) and type-X collagen (E).
