# A platform for multi-modal single nucleus spatial genomics for molecular tumor analysis

## Abstract

Project Summary
Tumors reside within a complex multicellular ecosystem comprised of malignant and non-
malignant cells, where interacting cells and molecules are organized in space and time. The
diversity of these cells and their interactions affect cancer progression and drug response and
resistance, and present opportunities for more precise diagnostics and therapeutics. In this
proposal, we build upon our recent invention of Slide-tags, a single-cell spatial genomics
technology, to enable facile, spatial profiling of human tumors. We will apply Slide-tags across
a broad range of tumor specimens to enable future adoption with minimal training and equipment.
We will extend Slide-tags to measure not only transcription, but also epigenetic states and
genome variation within individual cells in the tumor microenvironment. Our novel computational
pipelines will allow the seamless integration of molecular, cellular and histological
understanding in tumors: they will enable the spatial localization of cell types within complex
tumor environments, the identification of spatially varying gene expression patterns driven by
pathology, as well as the organization of cellular niches. The innovations from this project will
yield a robust, multiomic spatial platform for the routine profiling of human tumors at scale.
Applying this platform will revolutionize our ability to discover changes in tumor spatial and
molecular organization during disease progression and treatment, provide new biomarkers for
diagnostics and prognostics, and highlight new therapeutic avenues.
