Title: Spatial and Single Cell Analysis: Colorectal Cancer and Human Diversity

We used single cell RNA-seq data from 63 patients across three countries (Singapore, S Korea, Belgium) to update the Consensus Molecular Subtype (CMS) classification of colorectal cancer (CRC). We identified a pervasive transcriptomic and genetic dichotomy among malignant cells, based on which we defined two major CRC subtypes: iCMS2 and iCMS3. These two subtypes showed substantially different pathway activation, mutational profiles and anatomical location, based on re-analysis of bulk tumour transcriptomes from 3,614 patients. Notably, microsatellite-stable and -unstable malignant cells within the iCMS3 class were highly similar, and both populations showed hundreds of differentially expressed genes relative to iCMS2 cells. The previously defined CMS4 (mesenchymal) CRC subtype included both iCMS2 and iCMS3 tumours, with the latter showing lower relapse-free survival.

 

Human diversity is a frontier of omics research – little is known about the effects of age, sex and ancestry on cell proportions and cell states. Within the Human Cell Atlas consortium, the Asian Immune Diversity Atlas (AIDA) team is mapping the landscape of immune cell variation within and across 19 Asian populations. Initial results are based on Phase 1 single cell RNA-seq data from >500 healthy individuals from 5 ancestry groups across three countries (Japan, Singapore, South Korea). AIDA data reveal systematic differences between demographic groups, suggesting that tailored diagnostic and therapeutic tests and strategies may be needed to fulfil the promise of Precision Medicine across the globe.

 

Moving into spatial omics, we developed BANKSY, an algorithm that unifies cell type clustering and tissue domain segmentation by constructing a product space of cell and neighbourhood transcriptomes, representing cell state and microenvironment, respectively. BANKSY’s spatial kernel-based feature augmentation strategy improves performance and scalability on both tasks when tested on FISH-based and sequencing-based spatial omics data. Uniquely, BANKSY identified hitherto undetected niche-dependent cell states in two mouse brain regions. Importantly, BANKSY is over an order of magnitude more scalable than most existing spatial clustering algorithms, and thus well equipped to handle modern spatial omics datasets at the million-cell scale and beyond.
