No transcriptional memory in MEF-iPSCs. (A) 10-MEF-iPSC-37 was indistinguishable from 10-MEF-iPSC-42 at the level of global gene expression. Cor Pearson correlation coefficient, P P value, X, Y log expression value. (B) No clustering of gene expression was observed in 10-MEF-iPSC-37 and 10-MEF-iPSC-42. (C) No functional GO term enrichment was observed between 10-MEF-iPSC-37 and 10-MEF-iPSC-42.
