This is a really cool finding, congrats! It also reminds me of a recent paper from John Lis's lab showing that LTR promoter transcription in the NMU enhancer attenuates its activity: pubmed.ncbi.nlm.nih.gov/42468524/. So it appears to be a broader mechanism?

Not everything was done in cancer cell lines. Our original observation: www.nature.com/articles/nat... (note that we did not call them SEs back then, but the TF clusters are very similar) was in mESCs. Observations in GAM from the Pombo group were also on mESCs.

The pluripotent genome in three dimensions is shaped around pluripotency factors - Nature
Using 4C technology, higher-order topological features of the pluripotent genome are identified; in pluripotent stem cells, Nanog clusters specifically with other pluripotency genes and this clustering is centred around Nanog-binding sites, suggesting that Nanog helps to shape the three-dimensional structure of the pluripotent genome and thereby contributes to the robustness of the pluripotent state.

I agree it's quite a reversal of the original conclusion. In the discussion, they note that cells in pathological states (cancer) might be more prone to forming SE hubs, which is indirectly supported by their cohesin depletion experiments. So SE hubs might be a pathological state.
