|

| Characteristics |
tissue: embryo
developmental stage: E06
sequencer: Nextseq550, High, 75 cycle

total RNA |
| Extraction protocol |
For single cell isolation from cy pre-implantation embryos, a whole embryo was incubated with 0.25% trypsin/PBS for around 10 min at 37℃, then dissociated into single cells by repeated pipetting, and dispersed in 0.1 mg/ml of PVA/PBS for preparation of single-cell cDNAs.
For single cell isolation from cy post-implantation embryos, the implantation site was dissected out from the uterus and the embryonic fragment containing the epiblast (EPI), amnion, hypoblast, and yolk sac endoderm was isolated manually. The fragment was incubated with 0.25% trypsin/PBS for around 10 min at 37℃, then dissociated into single cells by repeated pipetting, and dispersed in 0.1 mg/ml of PVA/PBS.
For SC3-seq analysis, cDNA synthesis / amplification from single cells and library construction from the cDNAs were performed as described previously [Nakamura et al. 2015, NAR, 43, e60; Ishikura et al. 2016, Cell Reports, 17, 2789].

| Description |
Single cell transcriptome of amplified cDNA from cynomolgus monkey embryo at E06
|
| Data processing |
All the reads were surveyed and the adaptor or the poly-A sequences were trimmed by cutadapt-1.3 with options "-e 0.1 -q 20 -n 2 -O 1 -m 30 -a CTCGAGGGCGCGCCGGATCC -g CTCGAGGGCGCGCCGGATCC -a AAAAAAAAAAAAAAAAAAAA -a TTTTTTTTTTTTTTTTTTTT". The trimmed reads with less than 30 bp were discarded.
Untrimmed and trimmed reads of 30 bp or longer were mapped onto the Cynomolgus monkey genome Macfac5.0 and the ERCC spike-in RNA sequences with tophat-1.4.1/bowtie1.0.1 with the “—no-coverage-search” option.
Mapped reads on the genome and the ERCC were separated, and the reads on the genome were converted into the expression levels (RPM) by cufflinks-2.2.0 using the “—compatible-hits-norm”, “—max-mle-iterations 50000", “—no-length-correction” and “—library-type fr-secondstrand” options and macfas5.0 reference gene annotations with extended TTSs.
Mapped reads were also processed with HTSeq v0.11.0 to calculate number of read counts per gene.
For the reference gene annotations used in cufflinks and HTSeq, we extended the TTSs of the reference genes up to 10 kb downstream to correctly estimate the expression levels of genes whose transcripts are longer than the reference toward the 3 prime.
