Figure 1From: Attributes of Oct4 in stem cell biology: perspectives on cancer stem cells of the ovary A schematic diagram representing the human Oct4 isoforms. Both Oct4A and Oct4B share identical exons 2–5. The differences between the two isoforms lie in exon 1. The self-renewal and pluripotent properties of Oct4 encoded in exon 1 (Adapted from [97] and [96]).Back to article page
