Sample GSM1395931 Query DataSets for GSM1395931
Status Public on Jun 12, 2014
Title Single cell mRNA-seq_MGH31_E05
Sample type SRA
Source name Single cell mRNA-seq_MGH31
Organism Homo sapiens
Characteristics patient id: MGH31
cell type: Glioblastoma
subtype: Mes
Treatment protocol Differentiated glioma cells were generated by transitioning gliomasphere cultured cells to DMEM + 10% FCS for 7 days.
Growth protocol Gliomasphere cell lines were cultured in Neurobasal Medium supplemented with 1x B27, 0.5x N2, and 10 ng/ml EGF/FGF.
Extracted molecule total RNA
Extraction protocol Single cells were sorted into TCL buffer (Qiagen, 1031576) + 1% beta-mercaptoethanol and RNA-seq libraries generated using SMART-seq (modified from Shalek, et. al, Nature 2013) .
Nextera XT DNA Sample Preparation Kit (Illumina, FC-131-1096) used for barcoding according to manufacturer's protocol
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina HiSeq 2500
Description processed data file: GBM_data_matrix.txt
Data processing Basecalls performed using Bcl2fastq 1.8 (Illumina)
Paired-end 25bp reads were mapped to the UCSC human transcriptome (hg19) by Bowtie (version 1.4.1, with parameters -n 0 -e 99999999 -l 25 -I 1 -X 2000 -a -m 15 –S)
Expression levels of all genes were estimated by RSEM (version 1.2.3, using the option estimate-rspd and default parameters) using only reads with exact matches
TPM values as defined by RSEM were added a value of 1 (to avoid zeros) and then log2-transformed. 5,948 genes with the highest composite expression either across all cells combined (average log2(TPM)>4.5) or within a single tumor (average log2(TPM)>6 in at least one tumor) were included. Cells expressing less than 2,000 of these 5,948 genes were excluded. Data was centered by subtracting the mean.
Genome_build: hg19
Supplementary_files_format_and_content: Tab delimited file containing normalized, centered transcripts per million (TPM) values for 5,948 genes in each single cell and population controls
