Single Nucleus RNAseq dissection of choroid plexus tumor cell heterogeneity


ABSTRACT: To examine the cellular and transcriptional heterogeneity of choroid plexus tumors we determined the single nucleus transcriptomes of 23,906 nuclei from normal choroid plexus and choroid plexus tumors. The resulting cellular atlas profiles cellular and transcriptional heterogeneity, copy number alterations, and cell-cell interaction networks in normal and cancerous choroid plexus. We observe changes in choroid plexus tumor epithelial cell gene transcription that correlate with genome wide methylation profiles. In addition, we characterize tumor-grade-specific tumor microenvironments that include altered macrophage and mesenchymal cell states, as well as changes in extracellular matrix components.
