New Microfluidic Platform Maps 3D Genome Structure and Accessibility in Native Tissue

Researchers have developed Spatial-ATAC-Hi-C, a microfluidic technology that simultaneously profiles 3D genome organization and chromatin accessibility in intact tissue sections. Applied to mouse and human brains, the method reveals distinct regulatory programs in neuronal and non-neuronal cells. In glioblastoma and astrocytoma samples, it identifies spatially resolved copy number variations and structural variants, offering a new tool for studying tumor heterogeneity and gene regulation in native contexts.

3D lamprey brain atlas maps ancient vertebrate brain evolution

Chinese researchers have built the first 3D spatial single-cell atlas of the lamprey brain, enabling reconstruction of ancestral vertebrate brain features and revealing conserved gene expression and neurogenesis patterns with mammals; published as a Science cover article on June 19, 2026, the work suggests early vertebrate brains were already well-partitioned and provides a new resource for brain-evolution studies.

Single-cell proteomics maps human liver zonation and its fragility in diseased tissue

Researchers used advanced scDVP to profile hundreds of hepatocytes from 18 people, building a high-resolution map of protein gradients along the liver's porto–central axis. They quantified ~2,500 proteins per cell, showed roughly half are zonated, and introduced gradient-based analysis to quantify zonation without binning. Cross-species comparison with mice revealed shared and human-specific zonation features; in tissues with disrupted architecture, zonation is broadly lost. The study delivers an open-access liver proteome resource and a framework applicable to spatial proteomics.
