Fig. 6From: A comparative study of endoderm differentiation in humans and chimpanzeesGlobal reduction of variation in gene expression from the iPSCs to primitive streak state. Box plot of the log2 variance of expression levels for each gene. Variation in gene expression levels are significantly reduced from iPSCs to primitive streak (P < 10−15 in both species) but not in subsequent time points (P > 0.5 in both species)Back to article page
