Figure 4. The DNA methylation profile in DMR1 of the porcine H19 gene locus.

Figure 4

Sodium bisulfite sequencing revealed that the percentage of unmethylated CpGs in (A) undifferentiated skin stem cells at passage 2, (B) undifferentiated skin stem cells at passage 5 (cultured for 25 days in the absence of differentiation media), and (C) D25 PGC-like cells was 81%, 76%, and 99%, respectively. (D) Porcine oocytes served as a control for the expected maternal imprint (98% unmethylated). Open and black circles represent unmethylyated and methylated cytosines, respectively.
