Characterization of tumor initiating cells from human glioblastoma multiforms by scRNA seq

ABSTRACT: Radial Glia (RG) cells are the first neural stem cells to appear during embryonic development. Human embryonic RG cells demonstrates a specific set of gene expression compared to other type of progenitor cells. The goal of this study is to characterize the potential origine of tumor initiating cells of human glioblastoma multiforms by single cell RNASeq analyses of freshly sorted glioblastoma cells. The objectives are: 1)idetify RG-like cells in adult brain tumor; 2) reveal transcriptionally dynamic clusters of RG-like cells, that share the profiles of normal human fetal radial glia and that reside in quiescent and cycling states; 3) signaling pathways that mediate the transition among the different stages of RG-like cells; 4)genomic aberation analyses to reveal the potential hierarchical tree of RG-like cells.

Project description:We sought to characterize cellular heterogeneity in the human cerebral cortex at a molecular level during cortical neurogenesis. We captured single cells and generated sequencing libraries using the C1TM Single-Cell Auto Prep System (Fluidigm), the SMARTer Ultra Low RNA Kit (Clontech), and the Nextera XT DNA Sample Preparation Kit (Illumina). We performed unbiased clustering of the single cells and further examined transcriptional variation among cell groups interpreted as radial glia. Within this population, the major sources of variation related to cell cycle progression and the stem cell niche from which radial glia were captured. We found that outer subventricular zone radial glia (oRG cells) preferentially express genes related to extracellular matrix formation, migration, and stemness, including TNC, PTPRZ1, FAM107A, HOPX, and LIFR and related this transcriptional state to the position, morphology, and cell behaviors previously used to classify the cell type. Our results suggest that oRG cells maintain the subventricular niche through local production of growth factors, potentiation of growth factor signals by extracellular matrix proteins, and activation of self-renewal pathways, thereby contributing to the developmental and evolutionary expansion of the human neocortex. For study version 2, we have updated this data set to include additional primary cells that we infer to represent microglia, endothelial cells, and immature astrocytes, as well as additional cells from the developing neural retina, and from iPS-cell derived cerebral organoids. The genes distinguishing these cell populations may reveal biological processes supporting the diverse functions of these cell types as well as vulnerabilities of specific cell types in human genetic diseases and in viral infections. For study version 3, we have updated the data set to include additional primary cells, including those published in Nowakowski, et al., Science 2017: "Spatiotemporal Gene Expression Trajectories Reveal Developmental Hierarchies of the Human Cortex" (in press)
