Highly Synchronized Expression of Lineage-Specific Genes during In Vitro Hepatic Differentiation of Human Pluripotent Stem Cell Lines

Figure 4

(a) Bar graph showing the RNA expression levels of the primitive streak marker . The -axis indicates the day of differentiation and the -axis indicates RQ, where the calibrator’s RQ = 1. All six cell lines express the gene essentially only at day 2; therefore, the correlation between cell lines for the interval of day 0 to day 3 is very strong as indicated in (b).
