Integrating cytological images and spatial transcriptomics for cell segmentation with DISSECT.

New imaging approach reveals how immune cells rearrange around tumors after immunotherapy, deepening understanding of treatment response.

DISSECT addresses a key bottleneck in spatial transcriptomics—accurate cell segmentation—by combining cytological image features with transcriptomic profiles in a deep generative model that outperforms existing algorithms across heterogeneous tissues. Applied to gastric cancer samples before and after anti-PD-1 immunotherapy, it demonstrated utility for characterising spatial immune microenvironment changes relevant to treatment response.
