Querying Counterfactuals on Tissue Graphs with Supervised Disentanglement
Researchers have introduced Cellina, a new framework designed to predict how a cell's expression would change under different spatial neighbor contexts. This method formalizes 'tissue graph counterfactuals' as spatial interventions, either by rewiring cell connections or modifying neighbor expressions. Cellina decomposes a cell's intrinsic state from its spatial context, outperforming existing methods on benchmarks involving millions of cells from colorectal cancer and mouse brain tissues. AI
