Expansion in situ genome sequencing links nuclear abnormalities to aberrant chromatin regulation
Microscopy and genomics are used to characterize cell function, but approaches to connect the two types of information are lacking, particularly at subnuclear resolution. Here, we describe expansion i...

Say what?!?
'Here, we describe expansion in situ genome sequencing (ExIGS), a technology that enables sequencing of genomic DNA and superresolution localization of nuclear proteins in single cells.'

Misshapen Cells Could Be Quietly Shutting Down Important Genes | Science Featured Series
The structure of a cell's nucleus has long served as a visible clue to whether a cell is healthy or affected by disease. While scientists have made maj ...

To show the power of this approach, we applied ExIGS to progeria cells with nuclear lamina abnormalities

By combining expansion and 3D genome sequencing in the same nucleus, we can literally see how the abnormal lamin topology changes the structure of chromosomes

Great paper which combines expansion microscopy and in situ genome sequencing to map chromatin structure and selected protein targets in cellular nuclei. ExIGS was then used to explore how lamin protein and genome organization within nuclei changes during aging. www.science.org/doi/10.1126/...
