An extensive analysis of HERVH (a primate-specific endogenous retrovirus) expression in human pluripotent stem cells is presented, identifying a sub-population of cells within cultured human embryonic stem cells and induced pluripotent stem cells that has characteristics of naive-state cells — the study provides evidence for a new primate-specific transcriptional circuitry regulating pluripotency.
