Figure 6

The chondrogenic genes and MMP-1 expression profiles in Avas, Vas and Chondrocytes after 14 days in monolayer culture (a–e). Data shown are the means ± the standard deviation of triplicate technical replicates and 10 donors for each cell population. Gene expression is shown relative to the reference genes, glyceraldehyde-3-phosphate dehydrogenase (GAPDH).
