Primed to Naive-Like Conversion of the Common Marmoset Embryonic Stem Cells.

Mammalian pluripotent stem cells are thought to exist in two states: naive and primed. Generally, unlike those in rodents, pluripotent stem cells in primates, including humans, are regarded as being in the primed pluripotent state. Recently, several groups reported the existence of naive pluripotent stem cells in humans.
