Blue to red scale: heatmap representing the log2fold changes in nucleotide pool levels relative to E10.5 fetal tissues (placenta, heart, and brain) or E12.5 for fetal livers from wild-type (WT) dams. White to red scale: heatmap representing the total13C-enrichment (1-unlabeled) of nucleotides in fetal tissues from WT dams.
