!
Spatially resolved transcriptomics enables analysis
of molecular organization of the human DLPFC
!
Unbiased spatial domains, identified with 10x
Visium data and un-supervised clustering, look
beyond classic histological layers
!
Integration with single nucleus RNA-sequencing
data revealed distinct cell type compositions and
cell-cell interactions within spatial domains
!
Enrichment analysis link genes associated with
neuropsychiatric disorders to discrete spatial
domains.

Identification of Data-Driven Spatial Domains
BayesSpace: spatially-aware unsupervised clustering Spk
Ds
• K = 2: white matter vs. grey matter
• K = 9: classic histological layers
• K = 16: laminar with 2+ domains per histological layer
k = number of domains
s = domain number

Spot Deconvolution
Spatially Map Disease Ligand Receptor Interactions
Spatial Registration of Neuropsychiatric Data Sets
• Benchmarked 3 spot deconvolution methods with Visium-SPG
• Predicted cell type composition of spatial domains with
Cell2Location & Tangram – produced different results
• Identified Schizophrenia associated LR pairs in cell-cell
communication analysis
• Found co-localization of EFNA5 & EPHA5 in Sp9
D7
~L6
• Demonstrate reproducibility of snRNA-seq cell type population
spatial registration
• Gene set enrichment analysis of DE genes from ASD and PTSD
data show enrichment with specific spatial domians
Annotate 12 layer specific populations
