self‐renewal maintenance of embryonic stem cells. Recently, misexpression of OCT4 has
been also reported in some adult stem as well as cancer cells; a finding which is still
controversial. In addition to the previously described spliced variants of the gene (eg,
OCT4A and OCT4B), we have recently identified a novel variant of the gene, designated as
OCT4‐B1. In this study, we investigated a potential expression and function of OCT4B1 in a …
