Why 3D tissue imaging
See tissue biology in its full 3D context.
Traditional histology captures thin sections from complex tissue. 3D tissue imaging preserves depth, architecture, and spatial relationships for whole tissue imaging, spatial profiling, digital pathology, and quantitative analysis.
2D sections vs 3D context
Why can 2D tissue sections miss important spatial biology?
Thin sections capture isolated planes from a larger specimen. 3D tissue imaging expands the sampling volume, preserves depth, and retains connected tissue architecture.
Sampling coverage
Selected sections may miss sparse, localized, or unevenly distributed features.
More tissue volume can be examined across multiple regions and depths.
Spatial depth
Depth is reduced to a thin plane, limiting interpretation above and below the section.
Cells and structures retain their positions within the tissue volume.
Structural continuity
Branching structures appear as disconnected fragments across separate sections.
Vessels, nerves, glands, follicles, and immune structures remain connected.

What changes when tissue is examined in 3D?
More complete sampling
Whole tissue volume can reveal disease extent missed by selected sections
Whole-lymph-node OTLS imaging enabled volumetric assessment of breast cancer metastases, revealing metastatic extent that could be underestimated from selected 2D sections.

3D reveals architecture that cannot be measured from isolated cross-sections
OTLS preserved complete prostate gland networks, enabling measurement of branching, curvature, torsion, and connectivity. 3D architectural features were associated with biochemical recurrence across two cohorts.
Modern Pathology · 2026Added predictive information
Volumetric tissue context can improve downstream predictive analysis
Weakly supervised AI applied to 3D pathology data improved prognostic performance compared with corresponding 2D approaches, demonstrating the value of information captured across the tissue volume.

Which biological questions benefit from 3D tissue imaging?
3D tissue imaging is particularly valuable when interpretation depends on complex structures, cell distributions, rare features, or tissue organization across depth.
Convoluted structures
Vessels, nerves, glands, follicles, and crypts often require 3D context to evaluate shape, branching, and continuity.
Complex cell distributions
Immune cells, tumor regions, and stromal compartments can be interpreted in relation to nearby structures across tissue depth.
Sparse biological features
Rare cells, focal lesions, tertiary lymphoid structures, and localized features can be missed when sampling is limited.
Tissue-scale architecture
Whole tissue imaging helps reveal how compartments, regions, and structures are organized across the sample.
Where this matters
These capabilities support translational research, drug development, spatial biology, and digital pathology programs where intact tissue context affects interpretation.

Explore human duodenum tissue in 3D using eosin and TO-PRO-3 in an H&E-like visualization. Volumetric imaging preserves villous morphology and spatial organization across depth and can support quantitative analysis of villus dimensions, density, spacing, and regional variation.
This video presents a volumetric visualization of human duodenum tissue stained with eosin and the nuclear marker TO-PRO-3, then pseudocolored to create an H&E-like appearance.
3D tissue imaging reveals intestinal villi as continuous structures across the imaged volume, preserving information about their morphology, orientation, spacing, density, and regional organization. Viewing villi across depth also reduces the influence of sectioning angle and sampling location that can affect measurements from individual 2D sections.
With appropriate segmentation, the dataset can support quantitative analysis of villus number, height, width, volume, elongation, spacing, density, and variation across tissue regions.
These measurements are relevant to gastrointestinal research, including studies of celiac disease, where villous architecture may become shortened, flattened, fused, or otherwise disrupted. Quantifying these changes across a tissue volume could help characterize the distribution and heterogeneity of structural alterations.
