NCI workshop highlights tools and models to map how space shapes early cancer
Summary
National Cancer Institute convened researchers in systems and synthetic biology to examine how spatial organization, microenvironments and dynamics influence tumor initiation and progression and to chart priorities for perturbable 3D and computational models.
The National Cancer Institute hosted a virtual workshop bringing systems biologists, synthetic biologists and tissue engineers together to discuss how spatial and temporal information drives cancer initiation and progression. Organizers said the three‑day series will focus on transformation, tumor microenvironment and therapeutic resistance, and asked participants to use a shared Miro board to collaborate in real time.
Speakers described converging approaches: large‑scale single‑cell and spatial genomics to map premalignant cell states, dynamical systems models that reframe progression as population‑level attractor transitions, and engineering platforms that can place defined genetic or biophysical perturbations in millimeter‑scale regions of 3D tissue constructs. "Spatial biology is everywhere," Shannon Hughes, deputy director in the NCI Division of Cancer Biology, told the workshop, noting that advances in spatial transcriptomics and multiplex tissue imaging are rapidly enabling human‑tissue hypotheses.
Why it matters: participants argued that static snapshots of tumor tissue are valuable but insufficient; to link cell identity to function and risk requires perturbable systems that reproduce in‑tissue geometry and permit temporal control. Several presenters demonstrated such bridges: lineage tracing and evolutionary phylodynamics in mice, optogenetic control of signaling, programmable adhesion receptors to reshape multicellular neighborhood, and ultrasound‑triggered local gene delivery into printed tissues.
The workshop also highlighted practical barriers. Presenters repeatedly urged care in interpreting organoid and explant data — culture media, passage number and scaffold chemistry can drift transcriptional identity — and called for coordinated community standards and prioritized experimental targets so multi‑lab efforts can scale. Moderators closed by proposing a focused, collaboratively chosen set of tractable problems to build shared resources that would accelerate testing of spatial‑dynamics hypotheses.
