Spatially resolved chromatin architectures in mammalian brain tissues.

Spatial Hi-C reveals high-fidelity 3D chromatin structures in mammalian brain tissues at near-single-cell resolution.

• Why it matters: Understanding the spatial organization of chromatin is essential for decoding gene regulation during development and disease, but existing methods lack tissue context.
• What they did: The study developed spatial Hi-C, a high-throughput chromosome conformation capture technique, applied to mouse embryos and brains, achieving detailed 3D genome maps aligned with anatomical features.
• The result: This approach uncovered distinct chromatin topologies linked to brain microdomains, tracked neuronal maturity via chromatin interaction gradients, and enables spatially resolved regulatory studies within complex tissues.
