Identifying cell types and states remains a time-consuming, error-prone challenge for spatial biology. While deep learning increasingly plays role, it is difficult to generalize due variability at the level of cells, neighborhoods, niches in health disease. To address this, we develop TACIT, an unsupervised algorithm annotation using predefined signatures that operates without training data. TACIT uses unbiased thresholding distinguish positive cells from background, focusing on relevant markers identify ambiguous multiomic assays. Using five datasets (5,000,000 cells; 51 types) three (brain, intestine, gland), outperforms existing methods accuracy scalability. Integrating TACIT-identified reveals new phenotypes two inflammatory gland diseases. Finally, combined transcriptomics proteomics, discover under- overrepresented immune regions interest, suggesting multimodality essential translating biology clinical applications.

Abstract The intestine is a complex organ that promotes digestion, extracts nutrients, participates in immune surveillance, maintains critical symbiotic relationships with microbiota and affects overall health 1 . intesting has length of over nine metres, along which there are differences structure function 2 localization individual cell types, type development trajectories detailed transcriptional programs probably drive these function. Here, to better understand differences, we evaluated the organization single cells using multiplexed imaging single-nucleus RNA open chromatin assays across eight different intestinal sites from donors. Through systematic analyses, find compositions differ substantially regions demonstrate complexity epithelial subtypes, same types organized into distinct neighbourhoods communities, highlighting immunological niches present intestine. We also map gene regulatory suggestive differentiation cascade, associate disease heritability specific types. These results describe composition, regulation for this organ, serve as an important reference understanding human biology disease.

Abstract Spatial omics technologies enable a deeper understanding of cellular organizations and interactions within tissue interest. These assays can identify specific compartments or regions in with differential transcript protein abundance, delineate their interactions, complement other methods defining phenotypes. A variety spatial methodologies are being developed commercialized; however, these techniques differ resolution, multiplexing capability, scale/throughput, coverage. Here, we review the current prospective landscape single cell to subcellular resolution analysis tools provide comprehensive picture for both research clinical applications.

Abstract While technologies for multiplexed imaging have provided an unprecedented understanding of tissue composition in health and disease, interpreting this data remains a significant computational challenge. To understand the spatial organization how it relates to disease processes, studies typically focus on cell-level phenotypes. However, images can capture biologically important objects that are outside cells, such as extracellular matrix. Here, we describe pipeline, Pixie, achieves robust quantitative annotation pixel-level features using unsupervised clustering show its application across variety biological contexts platforms. Furthermore, current cell phenotyping strategies rely be labor intensive require large amounts manual cluster adjustments. We demonstrate pixel clusters lie within cells used improve annotations. comprehensively evaluate pre-processing steps parameter choices optimize performance quantify reproducibility our method. Importantly, Pixie is open source easily customizable through user-friendly interface.

Highly multiplexed protein imaging is emerging as a potent technique for analyzing distribution within cells and tissues in their native context. However, existing cell annotation methods utilizing high-plex spatial proteomics data are resource intensive necessitate iterative expert input, thereby constraining scalability practicality extensive datasets. We introduce MAPS (Machine learning Analysis of Proteomics Spatial biology), machine approach facilitating rapid precise type identification with human-level accuracy from data. Validated on multiple in-house publicly available MIBI CODEX datasets, outperforms current techniques terms speed accuracy, achieving pathologist-level precision even typically challenging types, including tumor immune origin. By democratizing rapidly deployable scalable annotation, holds significant potential to expedite advances tissue biology disease comprehension.
