Figure 1From: Selection and reliability of internal reference genes for quantitative PCR verification of transcriptomics during the differentiation process of porcine adult mesenchymal stem cellsPotential internal-control genes network. Evaluation of potential co-regulation (that is, common upstream regulator(s), including endogenous chemical molecules) among the 27 genes with expression ratio between samples and reference close to 1 in a large microarray analysis.Back to article page
