Before revision:  The OCT4 fluctuations in five minute intervals follow a Laplace distribution, with BMP4 addition provoking smaller changes and tighter self-regulation, particularly in the differentiated fate group.
After revision:  The OCT4 expression amongst neighbouring cells, we show that hESCs express similar OCT4 to cells within their local neighbourhood within the first two days of the experiment and before BMP4 addition provoking smaller changes and tighter self-regulation, particularly in the differentiated fate group.
