| Title |
4-cell embryo#1 -Cell#4 |
| Sample type |
SRA |
| |
|
| Source name |
4-cell embryo#1
|
| 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 19
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]
