Sample GSM3854982 Query DataSets for GSM3854982
Status Public on Sep 17, 2019
Title WT_TE_RNA seq_3
Sample type SRA
Source name Trophectoderm
Organism Mus musculus
Characteristics tissue: TE cells
strain: C57BL/6 X F1
development stage: E3.5
genotype: wild type
Extracted molecule total RNA
Extraction protocol For blastocyst, to separate ICM and TE from E3.5 embryos(Liu et al., 2016), blastocysts were broken using micromanipulator and washed three times in HCZB. The zona pellucidae of blastocysts were digested with 0.5% pronase E (Sigma) for 10-15 mins and washed three times again in HCZB. The embryos were then incubated in Ca2+-free CZB for 30 mins in 37 ℃, and the ICM and TE were separated into single cells by gently pipetting using a pipette with a diameter of 40–60 μm. Each sample was obtained about 10 cells from one embryo for amplification according the cell shape. For placenta, total RNA was isolated from mouse placentae using Dynabeads™ mRNA DIRECT™ Purification Kit (Thermo Scientific™).
For blastocyst, the cDNA library were prepared by SPAPK DNA Sample Pre Kit (Enzymatics) for sequencing using an Illumina HiSeq X Ten sequenator. For placenta, RNA-seq library were prepared by VAHTS mRNA-seq V3 Library Prep Kit for Illumina® (Vazyme), and then applied for deep sequencing on Illumina NovaSeq6000 platform.
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model HiSeq X Ten
Description TE obtained by Intracytoplasmic wt androgenetic haploid ESC injection
Data processing RNA-seq reads were mapped to the mm9 reference genome using Tophat (version 2.1.1). The gene expression levels were calculated by Cufflinks (version 2.1.1). The expression levels for each transcript were quantified as Fragments Per Kilobase of transcript per Million mapped reads (FPKM).
