What role does c-Myc primarily serve during the *maintenance* phase of pluripotency?
Answer
It enhances the efficiency and speed of somatic cell transition
Historical evidence indicates that c-Myc, while used in initial reprogramming cocktails, is dispensable for maintaining pluripotency itself; its main contribution is speeding up the reprogramming process by promoting chromatin accessibility.
