Title |
Late blastocyst #2 -Cell#1 |
Sample type |
SRA |
|
|
Source name |
Late blastocyst #2
|
Organism |
Homo sapiens |
Characteristics |
cell type: human preimplantation blastomere developmental stage: early blastomere tissue: human preimplantation embryos
|
Growth protocol |
Donated human preplantation embryos were dissociated into individual blastmeres and were separately amplied to set up single cell cDNA libraries.
|
Extracted molecule |
total RNA |
Extraction protocol |
Amplied single cell cDNAs were further amplied for another ten cycles of PCR.Then it was sonicated into 200~500bp fragments ,then the standard TruSeq DNA library preparation kit was used following the manualfactory suggestion protocol

Description |
Sample 76 cDNAs of individual cells of preimplantation embryos
|
Data processing |
Reads mapping: We used Burrows-Wheeler Aligner (BWA, Version 0.5.9-r16) to align the clean reads to the hg19 Refseq, with the options "aln -o 1 -e 60 -i 15 -q 10 -t 8" [Li H. and Durbin R. (2009) Fast and accurate short read alignment with Burrows-Wheeler Transform. Bioinformatics, 25:1754-60] Expression level analysis : The gene expression level was calculated by using RPKM method, We used all genes with RPKM ≥ 0.1 as expressed genes in the following analysis Use BEDTools(Version-2.16.2) to transform *.bam files into *.bed files.[Ref: Aaron R. Quinlan and Ira M. Hall. (2010) BEDTools: a flexible suite of utilities for comparing genomic features,Bioinformatics (2010), 26: 841-842] Merge the *.bed files from samples in the same stage [available on Series records] Use IGVtools to transform the merged *.bed files into *.tdf files for visualization [available on Series records] Genome_build: hg19 Sample_H1.expression.txt: hg19
