Summary: Found that mitotic chromatin (which has most transcription factors temporarily displaced) is reprogrammed 100 times faster than interphase nuclei in post-nuclear transfer to amphibian oocytes. Genes pass through a transient phase of high responsiveness to reprogramming factors during mitosis which alters cell fates and is an opportunity for reprogramming to pluripotency. This may be a result of histone H2A deubiquitination.
