GENE-21. A COMMON FETAL DEVELOPMENTAL ORIGIN FOR PFA EPENDYMOMA, PFB EPENDYMOMA, AND CEREBELLAR PILOCYTIC ASTROCYTOMAS?

Abstract Single cell RNA-sequencing (scRNAseq) of murine cerebellum at nine fetal and immediate post-natal (E10-P14) times points on >60,000 individual cells to identified >30 transcriptionally distinct cell clusters. Based on marker gene expression, many clusters resemble known cerebellar stem, progenitor, and differentiated cell types, while other clusters are more novel. Pseudo-time trajectory assisted in the reconstruction of known and …
