Before revision:  We evaluate the internal self-regulation of OCT4  , quantify the intra-cellular fluctuations and consider the diffusive nature of OCT4 over time for individual  and pairs of related cells.
After revision:  We evaluate the internal self-regulation of OCT4 using the Hurst exponent and autocorrelation analysis , quantify the intra-cellular fluctuations and consider the diffusive nature of OCT4 over time for individual and pairs of related cells.
