Expression stability values of candidate RGs during MCE and TD assessed by GeNorm.

<p>qPCR gene expression analysis was carried out on cDNA derived from differentiating cells. Gene expression data were converted to relative expression using the relationship (E+1)^−ΔCt and data was analyzed using GeNorm algorithm, yielding the rank order of gene expression stabilities during MCE (A) and TD (B). M, the average stability measure, was determined for each candidate RG. RGs with the lowest M are considered as most stable.
