Sample GSM3398389 Query DataSets for GSM3398389
Status Public on Feb 15, 2019
Title RNA-Organoid-D45_53BP1KO1 replicate 2
Sample type SRA
Source name Cell Line
Organism Homo sapiens
Characteristics cell type: Human Organoid D45
cell line: derived from H9 (day 45)
genotype/variation: 53BP1 KO
Treatment protocol The EB formation medium (DMEM/F12 with 20% knockout serum replacement, 3% ESC-quality FBS, 2 mM GlutaMAX, 0.1 mM nonessential amino acides,) was supplemented with Dorsomorphin (2 µM), WNT inhibitor (IWR1, 3 µM), TGF-ß inhibitor (SB431542, 5 µM) and Rho Kinase inhibitor (Y-27623, 20 µM). Starting form Day4, EBs were fed with cortical differentiation medium (Glasgow-MEM, 20% KSR, 0.1 mM NEAA, 1 mM sodium pyruvate, 0.1 mM ß-ME, 1% anti-anti), supplement with WNT inhibitor (IWR1, 3 µM), TGF-ß inhibitor (SB431542, 5 µM), Cyclopamine (2.5 µM) and Rho Kinase inhibitor (Y-27623, 20 µM). On Day17, EBs were embedded in matri-gel droplets and transferred onto low-attachemnt 6-wells and cultured in suspension using DMEM/F-12 supplemented with 1% N2 supplement, 1% Lipid concentrate, 2% B27suppmenent without Vitamin A, and 1% anti-anti under 40% O2/5% CO2 conditions on shaker. Starting from Day30, medium was changed to 50% DMED/F-12, 50% Neurobasal media, 0.5% N2 supplement, 1% GlutaMax, 0.05 mM NEAA, 0.025% human insulin, 0.1 mM ß-ME and 1% anti-anti, supplemented with 2% B27.
Growth protocol Cerebral organoids were generated based on previously published methods with minor modifications20,21. In brief, hESCs were dissociated to single cell suspension using Accutase and seeded onto low-attachment 96-well plates (Costar, 7007) at a density of 9,000 cells per well to aggregate into embryoid bodies (EBs).
Extracted molecule total RNA
Extraction protocol RNA was purified with the GeneJET RNA purification kit (ThermoFisher Scientific, K0732). The cDNA was reverse transcribed from 300 ng of RNA, using SuperScript IV reverse transcriptase (ThermoFisher Scientific, #18090050) with random hexamers. RT reactions were performed in triplicate to minimize variability.
total RNA with the TruSeq Stranded Total RNA Library Prep Kit according to the manufacturer’s directions (Illumina, San Diego, Ca.) Paired end 100 cycle sequencing was performed on HiSeq 2000 or HiSeq 4000 sequencers according to the manufacturer’s directions (Illumina.)
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina NovaSeq 6000
Description RNA-Organoid-D45.all.counts.txt.gz
Data processing Basecalls performed using CASAVA
Paired-end 100-cycle sequencing was performed on NovaSeq 6000 sequencers (Illumina). RNA-sequencing was mapped as described previously (Downing et al., 2012), and HTSeq (version 0.6.1p1) (Anders et al., 2015) was used to obtain gene-level counts and estimated CPM based on GENCODE (v24) (Harrow et al., 2012).
