Delighted that our story on chromatin architecture inside human cells is now published — the last chapter of my PhD. It was a pleasure working with @sergiocruzleon.bsky.social, @johannesbetz.bsky.social, and everyone involved. #teamtomo www.nature.com/articles/s41...

Molecular architecture of heterochromatin at the nuclear periphery of primary human cells - Nature Communications

The 3D organisation of chromatin inside a human cell is still not fully resolved. Here the authors reveal that in situ cryo-ET resolves individual nucleosomes and predicts DNA linkers, thus showing th...
