Gene expression analysis during chondrogenesis of ADSCs. ADSCs were cultured for up to 21 days. RNA extracts at day 0, 3, 6, 9, 12, 15, 18, and 21 were analyzed for gene expression of SOX9, COL II, COL I, and Aggrecan normalized to NC, respectively. Asterisk indicates P < 0.05 (vs. NC) as determined by one-way analysis of variance.
