Oct4A is expressed by a subpopulation of prostate neuroendocrine cells

Cancer stem cells are defined by their self‐renewal and multi‐potential capabilities and are hypothesized to be the source of primary and recurrent cancers. The stem cell properties of self‐renewal and pluripotency in embryonic stem cells and germ cells are regulated by Oct4A, a splice variant of the POU5F1 (Oct3/4) gene, while the function of the alternative splice variant, Oct4B, is unknown. Rare cells that express Oct4 were identified in several somatic cancers, however, the differential contributions of the Oct4A and Oct4B variants were not determined.
