Integration of single-nucleus and spatial transcriptomics reveals the molecular landscape of the human hippocampus

Overview

Welcome to the spatial_HPC project! In this study, we generated spatially-resolved transcriptomics (SRT) and single-nucleus RNA-sequencing (snRNA-seq) data from adjacent tissue sections of the anterior human hippocampus across ten adult neurotypical donors. SRT data was generated using 10x Genomics Visium (n=36 capture areas) and 10x Genomics Visium Spatial Proteogenomics (SPG) (n=8 capture areas). snRNA-seq data was generated using 10x Genomics Chromium (n=26 total snRNA-seq libraries).

Study design

Experimental design to generate paired single-nucleus RNA-sequencing (snRNA-seq) and spatially-resolved transcriptomics (SRT) data in the human hippocampus. (A) Postmortem human tissue blocks from the anterior hippocampus were dissected from 10 adult neurotypical brain donors. Tissue blocks were scored and cryosectioned for snRNA-seq assays (red), and placement on Visium slides (Visium H&E, black; Visium Spatial Proteogenomics (SPG), yellow). (B) 10μm tissue sections from all ten donors were placed onto 2-5 capture areas to include the extent of the HPC(n=36 total capture areas), for measurement with the 10x Genomics Visium H&E platform. (C) 10μm tissue sections from two donors were placed onto 4 capture areas (n=8 total capture areas) for measurement with the 10x Genomics Visium-SPG platform. (D) Tissue sections (2-4 100μm cryosections per assay) from all ten donors were collected from the same tissue blocks for measurement with the 10x Genomics 3’ gene expression platform. For each donor, we sorted on both and PI+NeuN+ (n=26 total snRNA-seq libraries). (This figure was created with Biorender)
