Figure 4From: Selection and reliability of internal reference genes for quantitative PCR verification of transcriptomics during the differentiation process of porcine adult mesenchymal stem cellsRelative mRNA abundance of COL1A1 and DBI nonnormalized and normalized with three or five internal control genes. Pattern of COL1A1 and DBI expression before and after normalization by using a NF calculated with three or five most-stable internal control genes from geNorm analysis (see Figure 3). * P < 0.05 for Tissue × Day interaction; #P < 0.05 for Differentiation × Day interaction at each time point. See Table S3 for overall statistical results.Back to article page
