Figure 1From: The roles of integrin β1 in phenotypic maintenance and dedifferentiation in chondroid cells differentiated from human adipose-derived stem cellsGene 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.Back to article page
