Quake TI - Single-Cell RNAseq analysis of infiltrating neoplastic cells at the migrating front of human glioblastoma AID - 10.1101/165811 DP - 2017 Jan 01 TA - bioRxiv PG - 165811 4099 - http://biorxiv.org/content/early/2017/07/19/165811.short 4100 - http://biorxiv.org/content/early/2017/07/19/165811.full AB - Glioblastoma is the most common primary brain cancer in adults and is notoriously difficult to treat due to its diffuse nature. We performed single-cell RNAseq on 3589 cells in a cohort of four patients. We obtained cells from the tumor core as well as surrounding peripheral tissue. Our analysis revealed cellular variation in the tumor’s genome and transcriptome, We were able to identify infiltrating neoplastic cells in regions peripheral to the core lesions. Despite the existence of significant heterogeneity among neoplastic cells, we found that infiltrating GBM cells share a consistent gene signature between patients, suggesting a common mechanism of infiltration. Additionally, in investigating the immunological response to the tumors, we found transcriptionally distinct myeloid cell populations residing in the tumor core and the surrounding peritumoral space. Our data provide a detailed dissection of GBM cell types, revealing an abundance of novel information about tumor formation and migration.
