Sample GSM8632174 Query DataSets for GSM8632174
Status Public on Nov 21, 2024
Title LMNSC01 human cell line, replicate 2,scRNAseq
Sample type SRA
 
Source name brain
Organism Homo sapiens
Characteristics tissue: brain
cell line: LMNSC01
cell type: neural stem cells
genotype: wild type
treatment: no treatment
Treatment protocol no treatment
Growth protocol LMNSC01 and LMNSC02 cells were grown in T-75 flasks in NeuroCultTM NS-A Basal Medium (Human) (Stem Cell Technologies, Cat# 05750), supplemented either with NeuroCultTM NS-A Proliferation Supplement (Human) (Stem Cell Technologies, Cat# 05751) or NeuroCultTM NS-A Differentiation Supplement (Human) (Stem Cell Technologies, Cat# 05752), basic Fibroblast Growth Factor (bFGF) at concentration 10ng/mL (Stem Cell Technologies, Cat# 78003), Epidermal Growth Factor (EGF) at concentration 10 ng/mL (Stem Cell Technologies, Cat# 78006), and heparin at 0.2x104% concentration (Stem Cell Technologies, Cat# 07980#) under physiological hypoxia conditions at at 4% O2 and 37C.
Extracted molecule total RNA
Extraction protocol LMNSC01 and LMNSC02 cells were dissociated from T75 cell culture flasks and counted, and a targeted recovery of 15,000 cells was calculated for each sample by loading a concentration of approximately 15,000 cells.
The library constructed following the manufacturer’s protocol. Library quality control was based on Agilent Tapestation 4200 HS D1000 screentapes (Agilent Technologies, Waldbronn, Germany). Multiplexed library pool was based on Agilent Tapestation 4200 HS D1000 and Kapa Library Quantification Kit for Illumina platforms (Kapa BioSystems, Boston, MA)
Cells were immediately processed with the 10× Genomics Chromium Next GEM Single Cell 3’ v3.1 (Dual Index) kit (10× Genomics, Pleasanton, CA). Samples were loaded, cDNA amplified, and library constructed following the manufacturer’s protocol. Library quality control was based on Agilent Tapestation 4200 HS D1000 screentapes (Agilent Technologies, Waldbronn, Germany). Multiplexed library pool was based on Agilent Tapestation 4200 HS D1000 and Kapa Library Quantification Kit for Illumina platforms (Kapa BioSystems, Boston, MA) and sequenced at shallow depths on Illumina’s iSeq 100 v2 flowcell for 28×10×10×90 cycles for estimated reads per cell. After demultiplexing, libraries were normalized based on their reads per cell. Rebalanced pool QC was based on Agilent Tapestation 4200 HS D1000 and Kapa Library Quantification Kit for Illumina platforms and high depth sequenced on Illumina’s NovaSeq 6000 S4 v1.5 flow cell for 101×11×11×101 cycles.

Description 10x Genomics
Data processing The demultiplexing, libraries were normalized based on their reads per cell. Rebalanced pool QC was based on Agilent Tapestation 4200 HS D1000 and Kapa Library Quantification Kit for Illumina platforms and high depth sequenced on Illumina’s NovaSeq 6000 S4 v1.5 flow cell for 101×11×11×101 cycles.
scRNAseq data was analyzed by Illumina Partek™ Flow™ v12.1.0 bioinformatics software (https://www.partek.com/partek-flow/). Using two replicates for each of LMNSC01 and LMNSC02 cell lines, data were imported into Partek Flow, data were processed based on Illumina Single Cell 3' v3 protocol with estimated 13,705 cells, followed by pre-alignment QA/QC to assess the overall quality of the cells then further filtered by three quality control filters: Mitochondrial reads (>5%), the count of read between 500 - 10,000. Features where the value was <=1.0 in at least 99.9% of the cells, were excluded. PCA was made with 100 principal components, and the variance was set as the features contribute. For the UMAP the local neighborhood size was set at 30, a minimal distance of 0.3, distance metric was set as Cosine, 0 iterations, random generator seed 42, the initialize output values Random, and the number of principal components was set as 20. Normalization with the setting of log2(cpm+1) followed by differential gene expression (DGE) analysis using ANOVA to generate the statistical significant differential genes filtered by |FC|>2 and FDR < 0.001 by comparing between LMNSC01 and LNDSC02 cell lines for downstream analysis of Hierarchical clustering heatmap, gene set enrichment and Pathway analysis. Additionally, an Qiagen Ingenuity Pathway Analysis was done to explore the interactions between the DEGs based on enrichment score calculated relative to a set of background genes relevant for this experiment.
