Epigenomic Diversity of Cortical Projection Neurons in the Mouse Brain
Ontology highlight
ABSTRACT: Neuronal cell types are classically defined by their molecular properties, anatomy, and functions. While recent advances in single-cell genomics have led to high-resolution molecular characterization of cell type diversity in the brain, neuronal cell types are often studied out of the context of their anatomical properties. To better understand the relationship between molecular and anatomical features defining cortical neurons, we developed Epi-Retro-Seq, a method that combined retrograde labeling with single-nucleus DNA methylation sequencing to link epigenomic properties of cell types to neuronal projections. We profiled 16,971 single neocortical neurons from 63 cortico-cortical and cortico-subcortical long-distance projections. Our results revealed unique epigenetic signatures of projection neurons that correspond to their laminar and regional location and projection patterns. The methylomes of 16,971 mouse neocortical neurons from 63 cortico-cortical (CC) and cortico-subcortical long-distance projections were analyzed using Epi-Retro-Seq, a method that combined retrograde tracing and single nucleus methylome sequencing.
