FIG. 6.
Fold change in gene expression of selected chondrogenic markers in 3D cultures. Results are normalized (except for Col II/I ratio) in relation to the p0 seeding stock and presented as mean±SD with n=4. #, ¤, and * denote statistically significant difference to the corresponding monoculture and growth medium (same passage) and to the previous AC expansion level (same cell population and culture medium), respectively (p<0.05). Note the different scales on primary and secondary Y-axes. Color images available online at www.liebertpub.com/tec
