Spatial transcriptomics of fixed tissue micro-regions using Pick-Seq [melanoma]

ABSTRACT: Spatial transcriptomics and multiplexed imaging are complementary methods for studying tissue biology. Here we describe a simple method for transcriptional profiling of formalin fixed histology specimens based on mechanical isolation of tissue micro-regions containing 5-20 cells. Sequencing micro-regions from an archival melanoma specimen having multiple distinct histologies reveals significant differences in transcriptional programs associated with tumor invasion, proliferation, and immunoediting and parallel imaging confirms changes in immuno-phenotypes and cancer cell states.

SnFFPE-Seq: towards scalable single nucleus RNA-seq of formalin-fixed paraffin-embedded (FFPE) tissues

Project description:Profiling cellular heterogeneity in formalin-fixed paraffin-embedded (FFPE) tissues is key to characterizing clinical specimens for biomarkers, therapeutic targets, and drug responses. Here, we optimize methods for isolating intact nuclei and single nucleus RNA-seq from FFPE tissues in the mouse brain, and demonstrate a pilot application to a human clinical specimen of lung adenocarcinoma. Our method opens the way to broad applications of snRNA-Seq to archival tissues, including clinical samples.

C42B Micro-C

Project description:We performed Hi-C, Micro-C, and capture Micro-C in human prostate cancer cells and compared chromatin interactions called using different methods. By integrating Micro-C with NOMe-seq, ChIP-seq, and RNA-seq, we investigated the relationships among nucleosome positioning of regulatory elements, chromatin interactions, and transcription. This work provides a framework for understanding the chromatin interactions among regulatory elements, nucleosome-depleted regions, and transcription.
