Sus scrofa |
| Characteristics |
developmental stage: Pig pre-implantation embryos (E0-E14)
tissue: Embryos
|
| Extracted molecule |
polyA RNA |
| Extraction protocol |
A modified Smart-seq2 protocol (Gao et al., 2018; Wang et al., 2018)
Single cell was transferred into prepared lysis buffer contained an 8bp barcode. Then, the first-strand cDNA was reversed-synthesized and amplified in a reverse transcription (RT) mixture containing 4U RNase inhibitor, 100U SuperScript II reverse transcriptase (Invitrogen, Cat. 18064071), 1 mM dNTPs (TAKARA, Cat. 4019), 60 mM MgCl2, 3 µM RT primer with 10 µM TSO primer. After PCR incubation, the product was purified by 0.8×AMPure XP beads (Beckman, Cat. A63882). Biotin PCR was carried out and enriched. The single cell RNA-seq library was constructed according to the KAPA Hyper Prep Kits with PCR Library Amplication/Illumina series (KAPA, KK8054).

| Data processing |
Raw reads from scRNA-seq were split by 8 bp cell barcodes located on the Read 2 allowed 2 mismatches, besides, the 8pb unique molecular identifiers(UMIs) located on the Read 2 were switched to the identifier line of paired Read 1.
Then the Read 1 were processed to remove the template switch oligo (TSO) primer, low quality bases and polyA sequence. The trimmed reads were aligned against Ensembl Sus scrofa reference genome (Sscrofa11.1, GCA_000003025.6) using STAR software (version 2.7.1a) with default parameters.
The aligned reads were further assigned to the ensemble gene annotations (Sus_scrofa.Sscrofa11.1.98) using featureCounts (version 1.6.4). Gene expression levels were estimated by counting the UMIs located the genes after deduplication by UMI-tools, next yielded an expression matrix consisting of UMI counts for each cell and gene.
