(A) Venn diagram depicting the total number of genes upregulated in MEFs (1504) or mHEPs (532) undergoing reprogramming and the 454 common genes upregulated in both MEFs and mHeps at day 6 of reprogramming. Of these, 30 genes, listed in the adjacent table, encode for Transcriptional Regulators (TRs). The top diagram indicates the experimental outline of the DNA Microarrays expression studies performed in MEFs and mHEPs undergoing reprogramming.
