ATLAS-1: 3D Drug-Treated Cancer Cells
ATLAS-1 is a research dataset of single-cell 3D morphologies captured under different drug treatments.
It contains 1,500 WM266-4 human melanoma cells embedded in collagen and imaged using oblique-plane light-sheet microscopy. Each cell is released as a 1024-point point cloud sampled from a reconstructed surface mesh.
- Total cells: 1,500
- Classes / conditions:
nocodazole(500) — microtubule inhibitor; rounded morphologyblebbistatin(500) — myosin II inhibitor; elongated/spindle morphologycontrol(500) — untreated baseline variability
- Representations: point clouds (1024 pts/cell) and watertight meshes
- Intended use: benchmarking point-cloud models on real biological shapes; studying drug-induced 3D morphology
This dataset accompanies the PointMIL project (inherently interpretable point-cloud classification via MIL).
Dataset Summary
Cells were segmented, meshed with marching cubes (+ Laplacian smoothing), then uniformly sampled to 1024 points per cell from the surface mesh. Files are organized by condition with a metadata CSV that holds labels and basic experiment info.
Why ATLAS-1?
- Real, noisy, heterogeneous 3D cell shapes (not synthetic CAD)
- Clear treatment effects (rounded vs elongated) for interpretable benchmarks
- Comes with both mesh and point-cloud views for flexible pipelines
