Single-Cell Cross-Modal Transfer by Adversarial Fine-Tuning of Foundation Models

arXiv:2606.07676v1 Announce Type: cross Abstract: Spatial transcriptomics (ST) is a powerful tool for exploring biological properties dependent on structure, proximity, and interaction in tissue. The methods underpinning ST are developing rapidly but are limited in their ability to profile many thousands of genes at a subcellular scale. Although dissociated from tissue, it is known that the whole-transcriptome readouts of cells in single-cell RNA sequencing (scRNA-seq) retain information about their former in situ neighbourhoods, motivating computational methods to recover it. While paired ST

Why this matters
Why now

The rapid advancement of foundation models in AI, coupled with increasing sophistication in spatial transcriptomics and single-cell RNA sequencing, is enabling breakthroughs in linking dissociated single-cell data back to spatial contexts.

Why it’s important

This development could significantly enhance our understanding of biological processes at a cellular level, impacting drug discovery, disease mechanisms, and the development of synthetic biological systems.

What changes

Biological research gains a powerful new computational method to infer spatial organization from single-cell data, overcoming a key limitation of existing spatial transcriptomics techniques.
