Fig. 4From: Dual functional construct containing kartogenin releasing microtissues and curcumin for cartilage regenerationGene expression in the mesenchymal stem cell (MSC) aggregate cultures. The relative expressions of ACAN, COL1A1, COL2A1, and SOX9 by real-time RT-PCR on days 14 and 21 after aggregation. mRNA levels were normalized to glyceraldehyde 3-phosphate dehydrogenase (GAPDH) levels and are presented as fold changes compared to MSC aggregates alone. Data are shown as mean ± SD (n = 3). *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001Back to article page
